 Most ZDDP additives recommend a specific quantity in the oil for break-in, and then half that amount for each subsequent oil change. Yes, it is possible to get too much ZDDP in the oil and generate spalling of the cam lobes. So do your research. And when in doubt, read the directions!

 ===Installation===
 '''5.  Actual installation of the camshaft into the block.'''
-On a complete engine assembly, it is often helpful to install the camshaft BEFORE the crankshaft; in many cases the cam would be the first major part to be installed by the assembler after "final cleaning" of the block. (The cam bearings and block plugs are likely to be installed by the machine shop.)  If this is the case, it is very helpful to--if possible--set the block on the floor bellhousing-side DOWN, so the block is vertical.  The camshaft then can be lowered into the block straight down, and there's minimal effort needed to assure that the cam lobes and cam journals DO NOT nick the bearings.  If the cam MUST be installed horizontally, it is almost mandatory to use a "handle" on the front of the cam, and to take particular care that the cam doesn't bang into, or scrape across the bearings.  Whether vertical or horizontal, if the crankshaft isn't in the way, it's easy to guide the cam through the bearings with one hand while supporting the front end of the cam with the other.

-Used lifters should only be used on the very same cam, in the very same block, and in the very same positions they were removed from.

+Used lifters should only be used on the very same cam, in the very same block, and in the very same positions they were removed from. Chances that the lifter bores will be machined on the very same angles on a different block as the block the lifters came out of are about equal to you hitting the lottery. If you purchase a used flat tappet cam from a swap meet or yard sale, plan on using it for a doorstop. New lifters should not be used on an old cam, either. Given the reasonable cost of a new cam and lifter set (~$100 ca. 2012), vs. the cost of cleaning and repairing the damage done by a failed cam and lifters, the choice to use new parts is obvious.
+Used lifters and a used solid lifter camshaft can be used, it is unfortunate that the cam grinders themselves have published this false wives tale for a very long time. In the order of preference, new camshaft/new lifters, used camshaft/new lifters and then used camshaft/used lifters. It is also preferable that the lifters stay matched to the lobe but if you have mixed them up or sourced them from a different, all is not lost.
+Several things must be accomplished to make a used camshaft/used lifter deal work. Each of the lifters will require that you properly polish the bottom of the lifter using a piece of window glass and a new sheet of 600 wet/dry sandpaper. The sandpaper will need to stay lubricated with a light solvent, WD-40 or similar is a good choice. Keep the lifters flat but understand that lifters have a slight convex to them. As you polish them in a figure 8 pattern you should see the center polishing first, if not and the polishing reveals the entire bottom, the lifter is beyond saving. Coloring the bottom of the lifter with a dark color magic marker will help you to see you progress. After polishing, clean all of the lifters thoroughly, several times is best. For the used camshaft, you want to make sure that there are no nicks or injuries to the lobe surfaces. You must also change out your valve springs to the lightest tension possible, not checking springs but something with minimal pressure. Apply Cam lube (Moly) to all surfaces of the lobes and bottoms of lifters - make sure to spend time rubbing the moly into the metal. A motor oil with a high level of ZDP should be used for the initial break-in period, removed after 30-40 minutes of run time and a second dose of the same oil along with a new filter should be used until the first oil change. Also during the initial break-in period, the oil level should be raised one to two quarts to encourage splash lubrication. In some instances a slightly hotter spark plug might be required due to oil fouling.
+'''19. Failure to observe the lifters and pushrods turning with the motor running.'''
+If the lifter is not turning, the cam lobe is hitting on the same spot on the lifter every revolution and it won't be long until the lifter yields and then takes the lobe out with it. All lifters and all pushrods must be turning for successful engine operation.
 ==Lubrication==
 That pencil-point of contact between the camshaft lobe and lifter crown is under somewhere between 250,000 and 300,000 pounds per square inch of pressure, so it should come as no surprise that extreme pressure lubrication is required, especially at break in where the contact point between lobe and lifter is irregular. The break in grease applied to the bottoms of the lifters and to the cam lobes is all the lubrication there is during the initial 5 to 10 seconds of operation, until motor oil reaches the interface.
+===Comp Cams's position on break-in additive and nitriding===
+<blockquote>
+''"Due to federal legislation, motor oils no longer contain certain anti-scuffing agents that played a critical role in flat tappet camshaft break in. While incorrect valve spring pressure and not following proper break-in procedure are often the culprits, the changes in oil formulation have brought about a need for additional steps to be added to the break-in process.''
+<br><br>
+''COMP Cams has two ways to ensure proper break-in of flat tappet cams. COMP Cams Engine Break-In Additive (part #159) ensures that the camshaft will have the lubricants that it needs to seat the camshaft journals and lobe/lifter surfaces. This lubricant is poured into the engine crankcase after the camshaft and lifters have been coated with the initial break-in lubricant (molybdenum disulphide) supplied with the camshaft.''
+<br><br>
+''Another option for increasing flat tappet cam longevity is nitriding. Recently COMP Cams invested in a nitriding machine, the first of its kind owned by a major U.S. aftermarket camshaft manufacturer. Nitriding actually hardens the surface of the camshaft and tappet face by injecting nitrogen “needles” into the metal. The result is an ultra-hard surface on the face of the camshaft lobes and lifter face, which greatly improves the performance and break-in process for flat tappet cams. This process is an additional charge for COMP Cams camshafts, but for many extreme duty applications, it virtually ensures proper break-in and increased durability."''
+</blockquote>
+George "Honker" Striegel (owner of Clay Smith Cams) said the following in an article on Ford inline 6 engines (to be taken with a grain of salt): Lets talk about that special treatment Comp Cams offers, for an additional $110 dollars. It's true that nitriding a cam raises the Rockwell hardness to 55-60, however they do nothing to increase the hardness of their lifters and most everyone will agree that it's the lifters that go first, then take out the lobe. In fact, the tech at Comp Cams told me that once the cam is broke in, the nitrided surface breaks down and eventually matches the hardness of the lifter. Right.... Clay Smith, Isky, Crane, and several others, experimented with nitriding several years ago. They found that nitriding offered no advantage, simply because they couldn't offer a lifter with the same hardness, at an affordable price. Yes, lifters can be made to match the hardness, but at a considerably higher price (which is probably why Comp Cams doesn't offer them). Next they discovered that a cam, or crankshaft, that had been nitrated was more prone to cracking due to stress resulting from flex and temperature fluctuations. Once the surface is damaged in any way, it cracks and eventually disintegrates, which accelerates wear at an even faster pace. And as expected, the mismatched cam and lifter hardness accelerates wear on the weaker component (lifters), which is true on all metal parts where the hardness is mismatched, such as distributor gears. On a final note, the nitrided cam carries the same warranty as a non-treated cam. If the process is as good as they say, why don’t they offer an extended warranty on the treated cams?
+Cam manufacturers found the better solution was to produce cams cores with a higher nickel content, which raised the hardness to 42-46 on the Rockwell scale. By using lifters that match the hardness of the cam, which are affordable to produce, wear is greatly diminished. Today there are literally millions of consumers using high nickel cams, of which a very small percentage have had wear issues that are directly related to cam hardness. Cam failures, or lobe wear, can almost always be traced back to improper break-in, the use of cheaper motor oils, or the use of high volume oil pumps. As such cam manufacturers don't offer nitriding, simply because it isn't needed, especially if you use a good quality oil and follow the recommended break-in procedures, including a high quality break-in oil. On the other hand, if you insist on using a high volume oil pump and/or high pressure valve springs for boosted applications, then a treated cam might be better suited. Just be prepared to change out the lifters on a regular basis, which means pulling the cylinder head frequently, or spending several hundreds of dollars on chilled lifters.
+Comp Cams is a huge corporation with thousands of employees, which finds itself in the same position that Crane Cams was in not long ago. Considering many of the engines produced today don't benefit from cam swaps, and the dwindling economy, the demand for aftermarket cams is steadily dropping. So how does a large corporation suffering from a lack of sales, up the ante to get you to shell out those hard-earned dollar bills? Easy, they dream up a new product and convince the average uninformed consumer that it’s something they can’t live without. Sound familiar? Personally I can find better uses for my money.
+As for stock springs, (let's talk about inline motors for a minute), I’ll post a few facts and let you guys make your own decision. Personally, I think they are perfectly suited for the applications they are recommended for. Not only do they work well, they are less than half the price of aftermarket springs, and they are readily available from any local parts store.
+AK Miller (hot-rodder, racer, engine builder, and the Godfather of inlines) used stock SBF springs on every motor he built with excellent results, and commented that they were adequate for motors up to 6000 rpm with a .060 shim. He even used them successfully on his turbocharged motors, as did Bill Strobe (racer and engine builder). Mr. Miller was also a Performance Advisor for Ford Motor Company and Ford Racing, and was considered by many to be the worlds leading authority on inline sixes. Miller and Strobe joined forces on several projects and wrote numerous tech articles for Ford Motor Company and various magazines. In the 60’s he authored an article entitled “Horsing Around with the Mustang Six - Parts 1&2” for Hot Rod Magazine. In that article, he used stock 289 springs with a 260 duration cam, which raised the rpm capabilities of the Falcon six from 4500 rpm to 5500 rpm. Not bad for a piece of junk.
+The Schjeldahl Brothers, authors of the Falcon Six Cylinder Performance Handbook, have used SBF springs in their motors successfully, and recommend them in their handbook as an alternative to stock springs.
+Jack Clifford, founder of Clifford Performance and one of the most respected pioneer’s in inline performance, stated that spring pressures should not exceed 100# closed for inline sixes. Ed Iskenderian, founder of Isky Cams and the manufacturer for a majority of the camshafts sold by Clifford Performance, supported those recommendations as well.
+Next we get to Comp Cams, which only stocks two different profiles for the small inline six. While they will custom grind any cam profile you want, so will any other cam manufacturer, and usually for less money. A few years ago, before Classic Inlines came about, the most popular cam was Comp Cams H260. The spring they recommend for that cam, part number 902-12, is rated at 48# closed, and 146# open. This is actually weaker than our stock springs, which are rated at 54# closed and 150# open.
+Stock 289 springs are rated at 60# closed and 175# open, while this is only marginally better than the stock springs, I would use them over the Comp Cams springs or stock springs if I was given a choice. Next we have the stock 302 springs, which are rated at 80# closed and 200# open. Stock 302 springs are considerable stronger (40% closed, and 27% opened) and are perfectly suited for mild performance cams within a given rpm range.
+The suggested applications posted on the Classic Inlines website, were recommended by George "Honker" Striegel, who is the owner of Clay Smith Cams, multi record holder in drag racing, and another pioneer in inline performance. While George is renowned for his V8 race engines, he is no stranger to our inline sixes. Back in the sixties and seventies, AK Miller, Bill Strobe, and George built and raced a drag boat powered by a Falcon Six, setting numerous records. While racing boats, George won numerous world championships, and was the first driver to acquire the APBA Triple Crown with his competition jet-boat (the American Revolution).
+Ask anyone in the business (manufacturing or professional racing), that has personally met George, and you'll get one common answer. He is perhaps one of the most knowledgeable persons in the business, and is certainly one of the most respected.
+Clay Smith grinds all of the camshafts sold by XXX. We currently stock seventeen different profiles (about 150 cams), on the shelf, ready to ship. However Clay Smith Cams has more than a 1000 masters on hand, which gives them the capability to make up just about any cam profile you can dream up.
+I could go on, but I think I’ve made my point. All of the above professionals, all experts in inline performance, have used and/or recommend the use of stock springs. Therefore, if I’m an idiot, at least I’m in good company.''

 ''"Overfill the crankcase by at least 4 or 5 quarts of oil so that the oil level comes to within an inch of the top of the oil pan. Install a set of fairly hot spark plugs with a gap of 0.050" to 0.060" to prevent oil-fouling of the plugs, which is otherwise inevitable under no-load conditions with all the extra oil aboard. During this operation, we want near-maximum oil flow, together with a maximum of oil vapors and liquid oil thrashing about in the crankcase so that the cam lobe and lifter interface lubrication is considerably better than marginal."''

+==Adjusting the cam timing or "phasing"==
-<blockquote>
+Cam phasing is the relationship of the camshaft position to the crankshaft position in reference to TDC. A change of 2 degrees at the cam gear equals 4 degrees at the crank.
-''"Due to federal legislation, motor oils no longer contain certain anti-scuffing agents that played a critical role in flat tappet camshaft break in. While incorrect valve spring pressure and not following proper break-in procedure are often the culprits, the changes in oil formulation have brought about a need for additional steps to be added to the break-in process.''
-<br><br>
+{{Note1}}When advancing/retarding the cam, be sure to check valve to piston clearance. Each degree of change effects valve clearance approximately 0.010". Example: If you advance the camshaft 4 degrees, you will '''lose''' about 0.040" clearance between the intake valve and piston, and you will ''gain'' about 0.040" clearance between the exhaust valve and piston. It will be the opposite if the camshaft is retarded.

-<br><br>
+The cam timing, or phasing, can be changed at the time of installation by using a multi-keyway timing set, or an adjustable cam gear like [http://www.cloyes.com/HighPerformance/Products/HexAJustTrueRollerSets/tabid/383/language/en-US/Default.aspx Cloyes Hex-A-Just].

+On timing sets that have no built-in adjustability, the cam phasing can still be adjusted in many cases. This is done by drilling the dowel pin hole of the cam gear oversize in order to use a bushing to advance or retard the cam gear. On engines where this isn't practical, an offset crank gear Woodruff key can often be used instead.

+In the majority of cases, installing the cam "straight up" (without any advance/retard added by the installer) is the correct way to install the cam and timing set. Many cam makers have already advanced (in most cases) the cam timing when the cam was made to suit the application. Unless the builder has access to an engine dynamometer or has advanced knowledge of the dynamics involved, advancing/retarding a cam is nothing but a shot in the dark as to whether it will result in any benefits at all. And there's the chance the engine output could be adversely affected by indiscriminately changing the phasing of the cam. The piston to valve clearance can be reduced enough to cause damage in some cases.
+==Effects of changing cam timing==
+===Advance timing===
+*Open Intake Valve Sooner
+*Builds more low-end torque
+*Decreases piston to intake valve clearance
+*Increases piston to exhaust valve clearance

 ==Roller cams are '''not''' immune==
 While the move has been made by the OEMs to stop using flat tappet cams and lifters in production vehicle engines (replaced by hydraulic roller cams and lifters), they are not immune to failure.
-The same type of oil additives should be used, because it is not just the cam and lifters that require a high pressure lubricant additive; the however do not use the heavy moly cam break in lube on a roller cam or lifter- it will cause much more problems than it will cure. Instead, follow the manufacturer's instructions. If those are not available for some unknown reason (all should be found online), use motor oil or a roller lifter-specific lube for the roller lifters and cam.
