hi again, just wondering is it a common thing for the rocker cover gasket to leak. i'm thinking its just starting to perish or something being rubber
Pull it off and check the seal. You can use gasket sealant to assist. I use Loctite brand "510 flange sealant". It seems to work for me...
i've had a closer look at it and touched it etc. and i'm just going to replace it with a new one, that way it shouldn't leak again for a long time.
