Problem With Oil Leaking Between The Trans And Engine?
 

Hello everyone! I have this small leak of oil coming from the trans and engine. I took it to the dealer and they said it was the "Rear main seal".
So they changed it under warranty. But a few days later I got the same F$&*#* leak again!!!:banghead: So I took it back today. Now they still haven't found the problem yet, they said its such a small leak that its not very noticeable, plus it is on the back of engine all the way on they top side. So what they have done is put this oil dye in the engine to see tomorrow with a black light as to where the oil is leaking from. Does anybody know what this could be? And if so what can be done? Thanks. Everyone on this site is 150 Times smarter then those so called techs that BMW has.

Which engine?

hopefully its not a headgasket.... could be a valve cover gasket and numerous other possibles

Dude, get away from Patrick. Between them and Knauz, they couldn't combine to produce one competent service department. If it wasn't the rear main seal, it might either be a cam seal or headgasket. A simple leak down test would easily allow them to rule the headgasket, or not.

make sure it's transmission fluid. if it's not then it's the valley pan gasket and coolant is leaking. it runs down the back and drips from the bell housing.

Sure its not the front seal?

he said it's originating higher up- not trans fluid. valley pan gasket leak?- not if it's oil lol.

Trans side= rear portion of the engine LOL.

Vinuneuro, you are right! Today I will know what the problem is, thats if they can find it. I already had it out with them yesterday. I told them my mechanic that I know could find the problem in 10 mins. I also told them if they can't do the job I will take it to my mechanic, pay him whatever, and then back charge them. They got so scared because they charged my warranty for the rear main seal leak, and that wasn't even the problem. These guys in my opinion SUCK!!!

But anyway, does anybody know where this oil might be coming from? Again its not Trans fluid, its not coolant fluid, I've had everything serviced, vally pan, valve covers, all hoses. What else is in the back of the engine upper part, leaking down and coming right around the trans and then leaking onto the lower strut bar right under the trans that butts up to the engine. Any info would help. I'm dealing with idiots... Thanks...
