engine assembly lube
--------------------------------------------------------------------------------
engine assembly lube needs to be used to protect your engine durring the first few minutes its running to protect the new parts as they start to lap in ,BEARINGS,CAM LOBES, LIFTERS,ROCKER ARMS,AND TIMEING CHAINS/GEARS, DISTRIBUTOR GEARS,ETC. ARE VERY IMPORTANT TO COAT TOTALLY DURRING THE ASSEMBLY PROCESS. first spray the contact surfaces with this ultra penatrateing moly-disulfide lube the carrier in the spray can allow the moly to soak into the metals surface,this stuff has been proven to coat the inside surface of rifle barrels and drastically reduce wear and friction even at temps of over 500 degs(F) and at pressures over 50,000psi,this forms your base layer,moly disulfide greatly increases the load and heat carrying ability of the lubericant and coating the surface with a layer of ultra-fine 20 micron moly before coating things with the lube gets the moly into the metal surfaces (check out the electron microscope photos) next use a good assembly lube that contains moly disulfide and/or zinc dialkyt-dithiophosphate both of which greatly add to the extreme pressure and heat resistance on the bearing or cam lobe surfaces.
heres some sources; http://www.msmoly.com/ http://www.mrmoly.com/catalog.html http://www.schaefferoil.com/data/221.html http://64.90.9.168/cranecams/pdf/214e.pdf http://www.cranecams.com/instructio...ain/camfail.htm
these are proven Anti-Wear Agents
These agents prevent wear due to seizure or rubbing surfaces. Compounds such a zinc dialkyt-dithiophosphate break-down microscopic hot spots and form a chemical filter which eliminates metal-to-metal contact.
also read this because the quality of the oil you use also has a big effect on how your engine wears during its lifetime. http://www.micapeak.com/info/oiled.html
REMEMBER WHAT YOUR TRYING TO ACCOMPLISH IS THE TOTAL PREVENTION OF METAL TO METAL CONTACT, AND ONLY THE BEST ANTI-WEAR LUBERICANTS PLACED BETWEEN CONTACT SURFACES AND FLOWING INTO THE CLEARANCES CAN DO THAT !
BTW DON,T FORGET TO PRELUBE THE ENGINE WITH AN ENGINE PRELUBER WHILE TURNING IT OVER BY HAND UNTILL OIL FLOWS FROM ALL THE PUSH RODS ONTO ALL THE ROCKER ARMS BEFORE STARTING A NEW ENGINE! and make sure your oil and coolent levels are correct too!

I am in the process of putting in a crate motor. They say to remove the distributor and a special rod goes in it's place that you attach to a drill motor to pre lube the motor prior to starting it. My question is, do you turn the motor over during this process? During or after....?

first thing to do it correctly you need this tool (I always weld a socket to the top to make it easy to attach a ratchet)

because a rod or a screw driver can,t seal the lifter oil gallery passages like a distributor body does, and yes to do it corectly you need to turn the engine over by hand useing a breaker bar on the crankshaft pulley retaining bolt about 6 full times slowly while your buddy supplies oil pressure by turning the oil pump primeing tool as fast as he can clockwise. keep turning the engine and primeing untill oil flows from ...EVERY LAST ROCKERARM..if not find out why not..BEFORE STARTING THE ENGINE!!


you can make one(a primeing tool) from an old distributor if you have one, by removeing the gear teeth with a belt sander and almost every part from the distributor body and welding a socket on the distributors main shaft so that when its inserted it seals the lifter gallery with the distributors body so you get oil pressure in both lifter gallerys while you turn the distributor shaft with a ratchet or a drill

Your the MAN!!!!!!!:_rock

You keep coming up with ALL of this FANTASTIC info, just when I'm doing my 85 engine!! WOW,,, I'm very impressed with all of your information.

Thank you VERY MUCH!!!

Keek up the great work!

just a tidbit..after grinding down the gears at the bottom, fix the top of the old distributor you are using for a primer to fit a drill motor...ya'll probably know that but I didn't see it mentioned,so I thought I would.....saves alot of arm work.

The last engine we bought I used a pressure luber which you put the oil into a pressurised can and screwed the end of the hose into the oil sending unit hole. It pressure lubed the whole engine before we cranked it. I put all 5 qts thru it. This makes sure there are no dry spots or pockets of air.

We borrowed it from Dicount auto who let me use it for free as I had purchased some parts from them.
