I wish I would have seen this 6 months ago:

All About Zinc

Recently there has been quite a lot of talk about ZINC, so we’re going to explain why that is as well as the difference it makes during break-in.
The word is out regarding the reduction of Zinc in today’s motor oils, but there is a lot more to the story. Specifically, not all Zinc additives and high Zinc content oils perform the same. Here are four facts related to Zinc. First, the oil additive generally referred to as Zinc is technically Zinc Dialkyl Dithiophosphate (ZDDP). As stated in the book Lubrication Fundamentals,” In heavily loaded applications, flat tappet cam followers operate on partial oil films at least part of the time. Lubricants with anti-wear additives are necessary if rapid wear and surface distress are to be avoided. oil additive Zinc Dithiophosphate is to provide anti-wear activity for the camshaft and lifters."
Second, Zinc (ZDDP) is not a lubricant until heat and load are applied. Zinc must react with heat and load to create the sacrificial film that allows Zinc to protect flat-tappet camshafts and other highly loaded engine parts.
Society of Automotive Engineers’ Automotive Lubricants Reference Book states, “ZDDP is the predominant anti-wear additive used in crankcase oils, although it is a class of additive rather than one particular chemical. Sensitivity of the additive to commence giving anti-wear protection varies inversely with the thermal stability of the additive.”
As a result, the third fact is that not all Zinc (ZDDP) additives react under the same level of heat and load. Zinc has different “Burn” rates. Some Zinc additives have slower “burn” rates that require more heat and more load to activate than other Zinc additives. For example, Passenger Car Motor Oils (PCMO’s) typically feature a faster burning Zinc than Diesel Engine Oils due to the lower compression ratios found in gasoline engines compared to compression ignition diesel engines. As a result, not all “High Zinc” oils have the same activation rate. Joe Gibbs Driven BR Break-In oil uses a “Fast Burn” ZDDP that activates quickly. Fourth, detergent additives “compete” against Zinc in the engine. Detergents are additives that clean the engine, but detergents don’t distinguish between sludge, varnish and Zinc – it cleans all three away. The “old school” theory on engine break-in was to run non-detergent oils, and this allowed for greater activation of the Zinc additive in the oil. Joe Gibbs Driven BR Break-In oil features a low detergent formula to allow the “Fast Burn” Zinc additive package to activate faster and to full extent.
Characteristics of Zinc and Detergents determine how quickly and to what extent an oil will provide sacrificial boundary film protection for your engine.
In order to achieve seamless protection for your flat-tappet camshaft or highly loaded engine, you need to establish the presence of the correct “Burn Rate” additives on the surface of the camshaft, lifters and other highly stressed engine parts. A properly matched set of assembly lubricants and break-in oil is of high importance.

Spent the evening working on this again, got the cam installed, valves adjusted and motor put back together. We did find one more issue, the freeze plug behind the cam was installed to deep. The cam was pushed up against it and rubbing. we knocked it out and FF is going to source a new plug.

I installed a Lunati VooDoo cam 213/219 @ .050 .515/.530 lift

It had a comp. 268H, 218/218 @ .050 .485/.485

You have me intrigued young man.
Did you get me a Blue Oval Badge to attach to the motor?


..........FYI, if that blue grating doesn't work for you, I can pick up a sheet of expanded metal this week at Central Iron. I think I saw a 4x4 sheet down there the other day.

I know Adam is a friend, and my appreciation to his help is huge.............and with all that being said...............Adam is meticulous when putting an engine together. He definetly has an eye for detail. Even the Silicone was perfect that he layed out.
His focus was amazing considering all the distractions he could have had Friday night.

We are lucky to have his wisdom in our club, and on this site for that mater.

Oh, and the new freeze plug is in, headers are on, and the YJ will be rolled back into the Barn tonight to start installation.

Tinkering tinkering tonight,.................just couldn't get motivated.

Tried some relective paint with the air brush on the two pullies. Looks wierd when you hit it with the camera flash.

In a round about way, I ended up scoring a set of 36 x 15.50 x 15 MT MTZ's.
I plan on putting them on the Bead locks for the trip to the Blessing.
