[curtisg40]

hi , i have just bought a g40 conversion thats just the engine rebuilt with all new gaskets and there is an oil leak can anyone suggest what it could be?

[GR40]

oil leak from where? g40 engines have a thousand places where they can leak! even a misfitted new gasket could cause a leak! or a gone o-ring? is it at the front or the back of the engine?

[curtisg40]

the drivers side at the front of the engine, there is a small amount of oil leaking and i dont know how to sort it.

Crank seal? I got a leak and its coming from there.

Sounds like the oil gallery seal in the head gasket, only real fix is a new head gasket. But your description is too vague, any pictures of it?
