Just use regular motor oil for oiling the bores. Don't use assembly lube on
the bores, pistons or rings. Some builders recommend dipping the whole
piston/ring assembly in oil before installing but I think that's overkill
and puts too much oil into the combustion chamber. I just smear a lot of oil
on the outer surface of the pistons just before assembly.
All other surfaces should be coated with assembly lube. Lubriplate is good.
Personally I use Redline's assembly lube. I use it on pretty much every
moving part including gears and chains. Don't forget to use some on the
sides of the connecting rod big ends.
When I add the motor oil just before startup, I pour one quart all over the
cam and rockers, and pour another quart directly over the upper timing chain
(U20) before adding the rest of the oil. Then I spin up the oil pump with a
drill to fill the oil passages so the motor will have oil pressure pretty
much immediately on startup.
This all may seem like overkill to some, but it's easy to do and why take
chances? The key to a good engine rebuild is attention to detail.

Subject: [Roadsters] Removing the cam
Thanks all for the really good info on cleaning the engine after machining.
So it appears that none of the soaps? would harm the bores? I wondered about
anything too acidic, "etching" the surfaces.
Oiling after cleaning I assume is regular oil.
Then once assembly begins the "assembly lube" is used. What is recommended
for that?
thanks,
Linda
