4.0 Head Gasket Oil Leak
 

My dealer showed me an oil leak along the passenger side of the engine
and said my head gasket needed to be replaced. He also said that DC
had redesigned the head gasket to prevent these leaks fro the oil
galleys.

My 2000 TJ has just over 98K miles and I switched to Mobil 1 for the
first time about two weeks ago. A google search turned up evidence of
this leak as a common problem, but most decided to ignore it as the
leak wasn't severe.

Anybody know the true story here?

Just to clarify something. There is a valve cover gasket and
a head gasket. Odds of the head gasket needing replaced because
of an oil leak is about as close to zero as you can get.

What you have is a small leak from the valve cover gasket that's
running back and down the side of your engine. Just like mine does. :)

A full synthetic will find holes regular dino won't. I'd just wipe
the engine side and watch for where the leak is. If your not getting
drips on the driveway I'd ignore it.

That's what I thought as well, The google search turned up reports
about the galleys feeding oil to the valves were under high pressure
and that the head gasket was susceptible to the leak.

I'll take your advice and keep a close eye on it.

Is it a seep or a leak?

A seep makes a mark and is quite normal, a leak drips.
