O ring 50 x 5mm

Is this ring a common cause for leak in behind the cam gear cover. Looks like I have seepage down on to the exhaust manifold.

Or would it be the smaller O ring inside?

Any tips on changing it if you think this would be the cause.

I'm going to do the belts and water pump, might as well change that too.

Thanks

Anyone? Don't make me go ask on the Pelican Board.

IIRC, removing the camshaft sprocket is a big deal. It would have to be a big leak for me to go looking there.

Are you going to use the updated water pump?

we (Dad and I) just did all that and I must agree: taking the cam sprocket off was a PITA. NOTE: mine had a soft hex bolt AND i think it was over torque'd

i would agree, if you're replacing all the other things the o-rings are Easy to do. IIRC there are 4 of them and it only requires taking off 3 bolts to get to each of them (9 total). the 4th (smaller one) is on the crankshaft.

I believe I have the updated one already.

Not that bad of a leak, but enough to smoke after the car has been parked awhile. Thought I would fix while the belt is off already. We'll see.
