My Ride: 2002 325xi
2002 325xi Oil pan gasket replacement HELP..

Hello everyone,

I have a oil leak coming from the oil pan gasket on my 2002 325xi with 133k, which I just confirmed today by a mechanic. I also confirmed that he would charge $600 to replace it...FML. I've been chasing this oil leak for a while and in the process I've changed the Valve cover gasket, OHFG, Dipstick O ring. At first I was thinking it the CCV, but he check it out and its fine (Hold 4.5 to 5 pressure) kinda wish it was (easier then the oil pan). But after we saw leaks its coming from the front and rear. So it not the rear main seal (Well I won't know until I replace the oil pan gasket). I'm losing oil way to quickly for me to wait around to get the money. I would say at least quart or so a every couple of days.

I did my research on how to replace it, I've found DIY's on 325i but no XI. If anyone knows how to do it and have a step-by-step guide with pictures that would be great (I'm not a tech, but I can def get the job done..hope?). Also what tools will I need to complete the job, hours? etc...

Any advice would be great.

Thank you in advance.

First thing you should do is to clean it up down there and then retorque all the oil pan bolts to the right spec. Sometimes they come loose and will leak oil.

If that doesn't work then the short version is this:
1.) Jack car (If you can't do this then stop now)
2.) Remove wheels (Ditto to above)
3.) Remove front axles (DIY available)
4.) Remove front driveshaft
5.) Jack engine up and support (DIY available)
6.) Lower front subframe (DIY available, make sure you replace the bolts)
7.) Remove front diff (4 bolts and it comes off)
8.) Remove oil pan (DIY available)
9.) Reverse to install

Hopefully tightening the oil pan bolts will help though.
