well, i started to notice an oil leak, dripping down onto the ground one morning.
i was told it was my valve cover gasket, so i replaced that. and now the oil leak is back for more. i went to a bmw shop and they said that it could be the head gasket because that looked like where it was coming from and also because when u replace the valve cover gasket the pressure moves to the weaker one. would this be the case? the weirdest part is the oil leak will go away for a while, then whenever i fill up my gas tank it'll start spewing out! it freaks the crap out of me. i know its oil and not gas, but anyone have a theory to this? please reply, thanks!

did you change the 4 rubber rocker shaft plugs along with the v/c gasket? they are a common oil leak on these cars. as far as the full gas tank, it doesn't make sense. are you sure it's not fuel? I have changed many fuel lines that leak from being dry and brittle with age. HTH

when you remove the v/c gasket, on both ends of the head there are 2 half moon cutouts that have rubber plugs in them. people sometimes don't change them and when they leak it looks as if the head is leaking. in your case it may very well be the head. I'm just saying check these first, it could save you alot of money.

Would a novice be able to do this himself?

To answer both questions......yes this a very easy job all you do is remove the v/c & gasket the shaft plugs are on the ends, you remove them by just prying them up. Question 2... if the engine has a single overhead cam it has the plugs, double overhead cam has the plugs built into the gasket. HTH

If it were the rubber shaft plugs, would the oil be leaking down the driver's side of the engine?

chances are no, since the engine is tilted towards the pass side.

ok let me ask you a few basic questions, is the engine a dohc? where do you see the oil? are you sure it's motor oil?

I just got it home from the shop. He sed i need a new oil pan gasket and oil sensor. He said he will charge $250 for the whole thing. Does this sound right? He said he needs to lift the engine or something to take it the oil pan off...

So i cannot do this by myself?

the job itself is not terrible, but it's not something I would want to do on my back without a lift. If you feel that you want to try and need some direction, just let me know.

No. You will have to undo the motor mounts, lift the engine and possibly drop the subframe a little. I would say it's tricky on the floor. $250 is not a bad price, I don't know what they charge for labor in your area but in this neck of the woods that is about 3-3 1/2 hours.
