Just finished changing the head gasket and now I got a knocking sound that seems to be coming from the top end.
Do you think it's caused by one of the lifters having air in them? Will they bleed themselves in time?
I did bleed them before putting them back in, but I guess it's possible that one got air inside somehow after bleeding.
If it is one of the lifters making the sound can I still drive it for a bit?
If I could drive for a few hundred kilometers I could pull the cams and retighten the headstuds at the same time when I bleed the lifters again.
Anyways here is a video of the sound:
Oh and I don't have VVT anymore so it cant be that...
