I'm curious to see what everyone is using when assembling their engines. I have heard everything from straight 30 weight oil to white grease to clevite bearing guard.

 

I use comp cams 104 engine assembly lube

 

I've personally(I know I'm nobody) used the white assembly grease, CC 104 Lube, 30W Oil, 15W-40 oil.

I have noticed a difference in none of them if planning on running the engine soon. If its gonna sit a while, I'd use the assembly lubes over oil but priming the oil system for a while wouldn't hurt before install. Oil is better then no oil

 

Royal Purple Max-Tuff assembly lube
Redline Assembly Lube
Childs and Albert Assembly Oil

 

+1, great stuff...

and great for scaring the **** outta your wife when she comes into the garage to smoke when youre assembling a motor with a friend...

 

Lucas oil additive works good, but it is very thick and clingy which makes it hard to "feel" things in the engine. Non detergent engine oil works just fine as well. Just always prime the engine before initial start-up regardless of what you use to assemble the engine.

 

also, forgot to add torco mpz!!!

 

dad has used white lithium grease on everything from his daily driver rock stock 350 to a 1,400 hp blown alchy injected bbc. i've used white lithium grease on all of my builds with no problems. most anything will work, you just need some sort of lube there until the oil pump can supply oil. always prime it before letting it run on its own. no matter what you use, just be sure to change the oil after a few hours of operation.

+1 on the Lucas engine oil additive. Just on bearing surfaces though.
+1 on priming the system too. We have a pressurized set up to prime LS motors, since you cant spin the pump without spinning the motor.

 

McLovin's spermicidal always worked for me

 

You're a sick man......

 

There are many different lubes for engine assembly. We use oil with the EOS in it. Of course, we dyno all our engines before they leave, so that helps.

I know other shops use the Torco MPZ. Just what you are comfortable with I guess. When I was in high school, the teacher said to use white lith grease, and I know that 355 is still running after 10 years.
