Leaky valve cover gaskets: 1998 2.5 DOHC

MaddMax · 01-30-2007, 03:58 PM

Anyone else had theirs leak? My driver's side is starting to leak enough to leave a drop of oil on the garage floor every night or so. The repair looks easy enough and apparantly the bolts are on with nearly no torque. Anyways, I was shopping around for the gaskets and I can't tell if the valve cover gasket is a one peice deal or two peice because there are two different part numbers for the DOHC valve cover gaskets. One part number is for the driver's side (~$13) and then there is a universal part number (~$5). Is this universal part number potentially the spark plug gasket? The FSM drawing is pointing to both the valve cover gasket and the spark plug gasket.

Each is on the completely otherside of the engine from eachother. Aren't these the gaskets that go around the holes for the spark plugs?

For each head, there is a gasket around the perimeter of the valve cover and one around the spark plug hole. The part numbers are different for these two gaskets but are the same for each head. It's not a difficult fix and there isn't much to screw up. I was lucky enough to have mine done under warranty yesterday.

Mine have been leaking on my 99 2.5 w/ 118,000 miles, for at least a year, if not longer. More so the passenger side. It hasn't become much of a problem, other than the oil dripping onto the exhaust and burning every so often. Everyone seems to recommend replacing the spark plug gaskets at the same time, since you're in there.

Thanks guys. This weekend I'm going to cleanup cover/head and give each cover bolt a slight turn and see if that helps. If not, I'll replace all the gaskets and bolt gaskets.
