Hello,
well, after all this time, the problem is finally resolved. It's a bit embarassing that it was not found sooner.

The problem was not exhaust at all, it was my connections to the fuel injectors. 2 of my injectors were staying on constant and over fueling the cylinders. I was smelling raw fuel and oil that was around my dirty car.

My new mechanic put new connectors on all my fuel injectors gave me a new valve cover gasket, and cleaned her up. (along with a tune up) and I don't smell anything now. So... what's really going on with that mechanic I trusted for over 7 years? He SUX big time. I hate him. all he wanted was for me to get so sick of the z car I'd give up and he'd sell me something he had like that 540i bmw. He would have made over 3k on me if I had bought that car from him for what he was asking. (I snooped around in the glove box looking for the registration, so I'd be ready for my speeding ticket. I never found the current reg, so I never got the car up to speed, but I did find out what he paid for it. I never told him I knew either.) So, now I'm greatfull I have a great new mechanic, and I hope I never get the headaches again. they were awfull. what was happening was when I would roll down the windows, the fumes would come straight from the engine into the car. I will take a picture if anyone would like to see.

 

congrats! oh and, told you you were crazy jk

 

Lisa, glad you got it fixed. You probably had to many brain cells anyway. But your headaches would now be nightmares with that beemer/maintenance $$$$$$$$$$$$$$$$$$

 

Thanks :-) I don't know about too many brain cells! I need all the ones I have left!
