My valve covers are still leaking oil after I got new rubber pressure grommets for the bolts and new valve cover gaskets. Does anyone else have this problem? Is this a problem with the 83's? The bolts are tightened all the way down. They just dont seem to put enough pressure on the valve covers. Is there some kind of sealant I could use? Any tips would be appreciated.
I've had a leak with a new aftermarket brand gasket that was cured with a Honda OEM gasket. It is not a chronic problem as far as I know. You could try a thin extra washer over the grommets to put more pressure on the rubber. Be careful to not over tighten your bolts. It won't help and may break off in the head.
I agree with hatchetman......In fact, I usually use a very thin finger spread coat of red high temp RTV on both sides of any valve cover gaskets I install, new or old........and the RTV holds most gaskets firmly in place while installing!
Just a long shot. Have you had the heads off this machine. Only there is a small oil flow control jet in the head that is prone to leak when disturbed and has a small O ring to seal it. If the oil leak is excess pressure then I would suspect this.
Otherwise I would concure with the crank oil seal theory.
