Title: Engine assembly lube
Post by: kalsig on March 07, 2011, 06:02:06 AM

Forgive me if I missed this in a previous thread but what engine assembly lube does everyone use on a complete rebuild. Also, there doesn't seem to be any way to prelube (develop oil pressure) before starting.
Thanks,
Ken

Hi,

I haven't ever heard of a special lubricant for engine assembly. I've always used motor oil (grade etc. same as the oil that i later filled the engine up with) which i think is fine. No need to apply the oil sparingly because as you mentioned the oil pressure arrives a bit later than usual, but no worries as the elapsed time the engine runs 'dry' is minimal since there's oil flowing even when cranking.

Hi Ken Welcome to the Forum, I use Graphogen Assembly Compound on all moving parts of the engine. when the engine is fitted and the oil is to the correct level, Take the spark plugs out and spin the engine until the oil light goes out (puts less stress on the bearings) then you know that the oil is circulated, then its ready for the initial first start up [-/

Its an anti-scuff paste that helps to bed in all parts of the engine :)

I have always used STP or Wynns lube suppliment on the crankshaft and camshaft bearings as well as any other moving parts I could get to. I always assemble piston and install them soaked in the engine oil I will use. I too crank the engine over without the plugs in until oil pressure arrives. Another thing I do particually after head work is to run a bead of oil around the outside of the pistons. This has the effect of bringing any small pieces of grit etc to the surface and they will burn off when the engine fires. It also helps to seal the rings and help with initial startup.
