I have already replaced the oil filter adapter gaskets. Next I will replace the oil pressure sensor and oil level sensor.. But if you look at the photos you can clearly see oil residue above the sensors. So I don't know it the sensors are leaking. Perhaps the oil is just running down coating the sensors with oil.

What do you think?

Thanks, Brook

One is the transmission pan seal. The other, half hidden under the engine itself, is the oil pan gasket (seal). To replace it properly you need to remove the engine from the car: it's not really a "gasket" - it's a silicone seal set into machined grooves in the halfcase.

That amount of seepage is minimal - you can buy a heck of a lot of oil for the $2,500 it will take in labor to replace the seal. You might be able to carefully try and tighten some of the pan bolts - there's a specific torque setting because the pan is a structural part of the engine. Some have attempted to clean the oil with solvents and use epoxies and glues on the seam. That's not even close to a proper repair.

Another look...................

FWIW, I'll bet that, if you were to get the car up on a lift and use Gunk Foaming Engine Cleaner on the lower part of the engine - NOWHERE ELSE - and carefully hose it off, you would have a long time before there was any noticeable seepage.

Do you have the info pertaining to what each bolt should be torqued to?

Like Sub said, that is not enough oil seepage to even raise an eyebrow at.

Oil pan bolt torque is 89 in/lb.

I don't see enough "seepage" to lose any sleep over. If you can live with adding a quart of (relatively inexpensive) oil if and when required, find something else to "fix".

A drop or two of oil on the pavement where you park the car is simply a nuisance.

There is a bright side!. My '98 model has been "seeping" oil from the crankcase seals for more than 100,000 miles. And I visualize that "seepage" as a continuous anti-corrosion coating for the remainder of the underbody parts and pieces (road draft affect). Most folks would be alarmed if they saw the oil coating on the underbody area aft of my powertrain.

Happy motoring.

S&B, Have you noticed much of a decrease in your bottom end oil leaks since you had the adapter gaskets replaced? If I remember correctly from your other thread you had 3-4 different shops look at it and got 3-4 different answers on what was leaking.

Big diffrence since I got the oil filter adapter gaskets replaced! No more smelling of oil while in traffic! After a new oil change, no puddle of oil in the driveway!

That's great news.... I would clean the bottom end up a little then drive it for a while and take another look. A lot of what your seeing could be left over from that adapter leak. The way I usually clean the bottom end is take it to the car wash and pull it up on a set of ramps then spray the bottom end down with engine cleaner then hit it with the high pressure. I haven't been banned from the car wash.... yet.
