What would you think if you saw this.........

I had my clutch replaced 1 year ago this month. While the engine was out I had my mechanic replace the rear main seal and the oil pressure warning light sender was replaced with a cap or plug ( because no new senders were in the area). Because of my busy schedual I had to have my mechanic do the work ( very highly respected around here).

So what do y'all think by first glance? Another rear main seal? It does not look like it is coming fron the flywheel inspection hole, but from where the g-box mates to the engine.

Any thoughts?

Oh boy....could be. This happened to me but I noticed it right away. Chaulked it up to a defective seal.

how was the warning light sender cap/plug done?

is the clutch acting normal?

It couldn't possibly be a bad seal on the breather cover or the thermostat? I know that those are both common sources of oil leaks that can lead to drips in that area.

I would guess it's either the rear seal or the cap/plug "thingie" your wrench put in.

don't forget the thermostat o-ring- they can get hard and brittle over the years and leak too.

Thanks for your replies everyone.

Before I drop the engine I would like to take a look at the thermostat o-ring everyone is talking about. At the risk of sounding like an idiot, where exactly would I find it? Is it near the engine oil cooler?

Its on the top of the engine in the back, just right behind the fuel injection manifold right next to the oil temperature switch.

Check idiot-light switch on the back of the engine (sits on the top). It's made of plastic that breaks and oil then leaks across lcutch housing leaving tell-tale dual oil drips.

It can be changed with engine in the car.

See, I've been told one cannot replace that sender with the engine in the car.

Looks like I'm pulling the engine this fall, if it makes it that long!

You can do a partial engine drop to replace the oil press. sending switch. It is explained at this site in a tech article. I did it with the help of a mirror. Good luck.

I must have rubber hands then or 930 is unusually easy car to wrench on (neither is true, I'm afraid), but I just took off the itercooler and replaced it w/o really looking at it.

I even took a picture if it's position:

Oh, ok. Thank you very much.

MY rear main seal leaks. To find it, I crawled under after the car had been running. Took one of those gauze rolls like the dentist uses and a pair of hemastats (wife is a dental assistant). I inserted the gauze in the hole where the engine and tranny meet. This confirmed what i didnt want to know. Although my plan is to fix it very soon, I have been living with it for a while.
