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, but it does not match the one out of the block. I took it back, and tried my luck with black dragon's rear main seal...but that did not work either. So i spent all of today scouring the internet for the origin of this seal from my block. The original seal is labeled "NDK - angus", as well as "SGL2 80 100 13 si". Even searching the measurements did nothing for me. The guy who helped me at motorsport auto (i forget his name unfortunately) told me that all L6 motors from L24 through L28 turbo blocks use the size they offer, but it does not seem to fit. Any help would be greatly appreciated. I will post pictures shortly. - Wes
