Thread: S1 2L Spread Bore Oil Galleries

I had a call from my friend yesterday , it looks like he has found the reason for his lack of oil pressure. It looks like the engine shop had taken out the two retaining bolts that hold the oil gallery in the block & when they fitted the galleries have not fitted the bolts. One of the photo's shows the block before it went for marching & second shows the missing bolts.

Good detective work! It had to be something along those lines. If you can't find them, I should have some in the shed you can have. Use a suitable Loctite threadlocker/ retaining compound to keep them in place. I just dismantled a large final drive sprocket nut that was fitted with 680 loctite 20 years ago and it wouldn't undo without heat application. Just ensure that the product is oil resistant and can operate at 150C. Mike. 5380
