Post Hesitation:Think it's a valvecover gasket problem

After aquiring a pretty mighty hesitation from 2k up to a little over 4k, I decided to change the spark plugs. The plugs we pulled on the driver side both had oil on them. We changed all four plugs and, well, that made it better for one day. So after closer inspection, the driver side of the motor looks like it has been getting oil on it most likely from the spark plug wells. Has anyone else had a problem with their valve cover gasket? I've got 40,000 miles BTW. I'll be taking it into the dealer tomorrow, but wanted to see if anyone else had a similar problem.

I had some leaking from my valve cover gasket due to a missing washer and improper torque. Torque spec for the valve covers on a 99-01 2.5L SOHC is like 4lb-ft, super light. I didn't think the gasket was a consumable, but it is conceivable that yours needs to be replaced.

Once I replaced the washer and torqued the bolts correctly, my leaking went right away.

I didn't notice any performance problems traceable to the valvecover issue, btw. Oil on the outside of the plug shouldn't influence it's performance at all. (Both my plugs on that side did have oil on the insulator above the threads.)

Thanks Colin,
Now that you mention it, oil in the wells doesn't justify oil on the bottom of the plug, which is what I had! Maybe I've got a bigger problem!! Damn. I had a valve cover problem with my 96 GSX and once it was replaced the plugs stopped getting fouled up though.
This will be under warranty no matter what though. I've got a 80,000 mile contract, but hoefully it's nothing big.

I had the valve cover gasket changed on my 98 before 36k. Just recently have been having more oil consumption also, so I will have to do another check.

Chad,

I'm sure you have scaned the posts on MY99 hesitation, stemming from the knock sensor.......right.

That is were 99% of my hesitation problem comes from.
