Can’t stop a leak

[mastercamper]

I personally would ditch the gasket, clean the surfaces really nice and apply a bead of high temp sealant that suits your liking.

2nd time I used RTV and a gasket. First time no RTV leaking at the same place. Next will be to do just the sealant.

Seals do work against this cylindric rectified surface. Problem is not the easy-to-see groove, but a microscopic edge produced by previous seal's lip. With just a 600 grit sandpaper by turning the piece you can "kill" that edge and there are no surprises later. This procedure is a must every time we change a seal without discarding the ground part. If not, that edge will cut the lip of the new seal in the first turns.

Another fix for the seal groove is an SKF Speedi Sleeve.

Has anyone tried the MAHLE front crankshaft seal? Saw it on O'Reilly site.

Mahle are well known, so it should be good.
