leaking valve cover gasket question
 

I completed a timing belt replacement, water pump, cam tensioner gasket etc. overhaul 60,000 k ago. Now I have oil leaks at various places at the valve cover gaskets. Can anyone tell me why this would happen at this point? I did also replace the spider hose during the over haul.

Thank you

Peter

Time to do it again.

Too much torque on the bolts?

Bad parts, too tight, wrong sequence, and probably not thoroughly cleaned...

Some time ago there was a post regarding if your PVC system (I know it is not called that) was plugged that put additional pressure on other gaskets. Thus some oil leaks were a result of the extra pressure.
