Oil leak around crankcase bolt

Post by Allen » Fri Mar 23, 2018 10:28 am

Hi

Oil is seeping out from one of the bolts on the crankcase when the engine reaches temperature. I have checked to see that the oil is not overfilled - it is near full when vertical but not over.

Any thoughts on a remedy?

Hi Allen, is the thread stripped? Or, is it the correct bolt, it may not be the correct length. Either way it sounds like its not torqued up properly. I am about tomorrow, give me a call if you like. Going over to Hideout leathers in the morning.

Cheers,
Rod

Hi Rod

Thanks for responding.

I have tried replacing the bolt with one from the exact same position on one of the other Drifters - torqued to 10nm. It is the only position with a leak.

Incidentally I have tried removing the crankcase cover and it is well and truly stuck..... if we can get it off, then cleaning it up and re-fitting with correct torque and pattern might be an idea. But need ideas of how to remove the thing.

I'll get Ashley to give you a call - does he have your number?

Update from f'book - not a leak so much as a drip from above.

Suggestions include '1500 cylinder weepage syndrome' and
a dripping air filter.

Hi Trev,

I spoke to Allen and it is coming from the breather pipe in the air box (right side) investigation and diagnosis remains ongoing.
