Looking for advice pls.
I’ve got an annoying oil leak from my sump bolt. It’s only a minor leak but I need to sort. The sump threads look fine and the bolt torques up OK. I have tried a new crush washer, but to no avail. There is no sign of any cracking to the sump.
What I have noticed is the surface on the sump where the washer sits is scored, and the old washer I took off is also scored. I am thinking this may have happened as a result of the sump not being properly cleaned of muck when previous oil changes were done??
Is this scoring enough to cause the slight leak I am experiencing? If so, what’s the best way to sort??
Cheers
Harold
