Just for clarification (and at the risk of taking one in the jibs), when I change the oil on my 944 I am draining it from the sump. There is no oil drain plug on the block. The drain on the block is for coolant.

Coolant in the block? whaaaa.. you drain oil from the oil pan, the drain plug is on the side of the pan, a 17mm i believe. oops 15mm i have been corrected

StoogeMoe

DBorror, you are correct. The only one you want is on the oil pan. And it is a 15mm.

Thanks! People seem to use "sump" and "oil pan" interchangeably. Just wanted to make sure I knew exactly what folks were talking about. There is another "plug-like thing" on the right side of my block that seems to have oil collecting on it. What is that then? I thought it was some sort of drain plug? Here is a picture of what I am talking about.

^no where near your drain plug... did u take that pic? it looks just like one i posted here

that would be your oil pressure relief valve or something that..

Neinfofo

yeah I know it is not near my oil drain plug. Trying to figure out what it is though. I just took it moments ago.

Neinfofo

I imagine that it is not good that there is oil dripping from it?

Do not drain the oil from the OPRV... holy moses... leave that thing alone! That's the oil cooler housing with the oil pressure sender. You're going to want to look on the same side of the car, lower, and back about a foot...

Neinfofo

Why is it leaking and how does it tighten? Could it just be loose?

joes

Check the torque specs for the oil pressure relief valve plug( 45 nm) and retorque it. If that thing blows you'll be in trouble.

Neinfofo

Will do. Does that thing have a crush washer like the oil plug?

Techno Duck

There is a crush washer on the regulator valve, replace it and torque if thats where its leaking from.

Thanks everyone.

It could be your oil sender or even your oil filter leaking. Once you pull your oil filter when you change your oil you will have a better look at everything down there from the top of the engine. Make sure you use a Mahle filter and not a generic filter when you do your oil. I would clean it up real good with carburator cleaner and give it a week then check it again to figure out where it is leaking from. Could even be the comming from the cam tower.

I will change the oil and clean it up real good to see what happens after that. Thanks for the info
