Can anyone tell me the acceptable main bearing clearance for my L28ET build? (F54 block) I have a Chilton Guide and it is definitely mentioned to check that they are correct, but the actual acceptable clearance measurements are not listed. (2nd error/omission that I have found so far...) Anyone help please?
Hello HybridZ, I have been in the process of rebuilding an L28 engine with mild cam i picked up for $250 with a 5 speed. The block is a F54 with N47 head and has P79 pistons. The previous owner said "it only needs new valve seals to run right"... So I hot tanked the block, installed new rings, valve seals, some bolts here and there, all gaskets, and seals...and some more parts (cant remember at the moment: nothing major though) Now that i am assembling the new engine, the rear main seal is of incorrect size. I originally ordered an aftermarket one off motorsport auto,
