Felpro intake gasket kit: MS96386

Valve covers are the same.

depending on mileage, you may want to consider removing the engine and doing all gaskets and seals... and washing everything down... it gets messy down there.

I would but I can't afford to have her out of commission that long right now :/

Is that the off road gasket? Or just the full kit

Nobody seems to answer the question of the off road gasket

I had an embarrassing amount boiling out at stop lights before I added the Lucas Oil Stopleak.

Any issues wroth using the stopleak? I've heard some horror stories about that stuff gunking up a motor

How do you determine which thread about your oil leaks you post to? Is it random, or is there some other method?

The only thread in which I am talking about leaks is this one. My others are about gaskets, cleaning the engine bay, restoring ride height, and spring codes. So what are you talking about?

So an update, swapped out the valve cover gaskets and then cleaned up underneath her and it appears she is still leaking. Had some financial issues so haven't been able to do much else since then. I looked today after driving for an hour or so after noticed smoke rolling from the passenger side and the only place I see smoke originating from is off of the driver's side cat. Oil drips just inboard of that when it drips on the floor. Only a drop here and there when cold but when running or shortly after its a couple drops a minute it seems like. Does that narrow down my options at all?

So here is something else to consider. It may not be an oil leak that is causing the smoke.....

If you are able to put the car up on a lift, check the exhaust and the cats and make sure that neither of the heat shields between the cats and the fiberglass foot well on both the driver and passenger side has come off.

Don't know if you have LT headers on your CE but this is more common with LT headers. The heat shield comes off and the heat from the cats begins to melt and burn the fiberglass footwell.

Just something to check and eliminate

I will check that out. I got hooker shorties on her. I haven't had a chance to check up close but it looks like the inboard side of the mounting plate for the cat has oil on it.

So I got minor seepage from a couple places but the reason for the smoke was from the filter adapter bolts needing to be retorqued
