I'm assembling a big block for race only application.Am mainly interested in piston/cylinder/ ring assembly lube.What have you used in this specific area of assembly when the engine won't be run immediately. It will sit for a while before firing up, as I haven't put the trans together yet. Thanks, Bill

Ya that was probably 30 years ago. Lol 😂
Kendal oil changed names at least twice since then. Brad Penn and now Penn Grade. Still great oil.

Scheafer 20w-50 racing oil. It looks kinda greenish. That is some sticky stuff.

You guys put some pretty heavy stuff on the rings(except the WD40 guy) I use Castle brand lube called Thrust on all my ring/piston assembly jobs. It's a little thicker than WD40 so it should hang in there longer until you fire it up. twocents

Lots of ideas here.I'm sure they all work well. My main concern is what will remain effective if I store it for a while before I fire it up. Thanks, Bill

I use 5W20Wt on all the bearing ,pistons and rings, cylinders walls get lube off of the residual oil on the rings and piston skirts and I wipe the cylinder walls several times to get the excess oil off of the cylinder walls with a clean white rag to get them as clean as possible after thoroughly cleaning them before assembling the short block. No assembly lube for me, the motor runs on oil, correct work thumbs
I use the cam lube call for by the cam maker on the lobes if it is flat tappet type cam and not a roller cam and lifter up wrench
you can not keep the motor to clean while prepping it and assembling it.
I do prime the motors and rotate them over on the engine stand with the spark plugs out and again before starting them in the car or on the engine dyno with the starter with the plugs out wrench up

I have been told by guys who build a lot of serious engines not to make the rings and lands sloppy wet as the oil creates issues, coking, etc on start up. In the old days, guys used to dunk the piston in a bucket of oil before installing it. Not good.

I use motor oil on the cylinder walls, rings, skirts, etc. Not dripping wet, just lubed. Bearings, cams, rocker gear, etc. gets GM EOS. I have some of the good old high zinc stuff that has followed me around over the years.

Pre-lube just before starting is also done.


If the results don't match the theory, change the theory.

Total Seal recomends using a powder they sell on rings, seats the rings faster, I used it and appears it works ok.

I've never had a ring seal problem even when I use to dip the complete piston in oil and never wipe the cylinder walls down to remove the excessive oil shruggy
I have also tried installing the rings and piston dry using the old Total Seal recommendation on their zero gap rings back in the mid 1970, only once though realcrazy shruggy

A few drops of oil in the ring grooves, wipe some oil on the skirts. WD40 on the cylinder wall after they have been thoroughly cleaned with ATF.

Nothing on the rings. Ever.

Wipe the bores with a white lint free cloth and Marvels Mystery oil, ATF or even WD-40 until the cloth comes out clean. Then put NOTHING on the cylinder walls unless you are using Total Seal’s powder or paste or whatever it is.

Then you use a QUALITY assembly lube and just put a light coating on the skirts. Real light. It should just cover the skirts and that’s it.

As you assemble the short block, you will notice that the lube on the skirts will migrate all around the bores, the rings will be LIGHTLY lubricated by that and there isn’t a bunch of oil loaded behind the rings. The engine will fire quickly, won’t smoke and the rings will be 99% seated before the engine runs 5 seconds.

You can see this on the dyno. Instead of the first 10-12 pulls showing big power gains as the rings come in, the power will be relatively stable as you begin your dyno work.

I use Torco assembly lube for everything. I never use oil. There is a separate cam lube and engine assembly lube. I don’t like assembly lubes that look like grease or pastes except for flat tappets.


Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston

If you don't run your engine right after assembly, it turns yellow and hardens. So much for lubrication there. I haven't used lubricate in years...

Rings go on the pistons dry. But I do make the face of them wet while doing the same to the skirt just before dropping it in the hole. I just don't want anything to be dry as a popcorn fart while assembling, rotating or on start up.
