Bmw leaks oil - BMW Forum

I just noticed that my 94 325is is leaking small amounts of oil. I took it to a local mechanic and he told me that the oil filter housing needs to be replaced. He wants to charge me over 500$ for it. Is this hard to do? How much of is an oil filter housing? Can I replace it by myself?

Hmmmm....As a guide realoem.com comes up with a price of $472 just for the housing and filter, so he is probably not to far out on his price if he's getting genuine parts, however are you sure its not just the 'O' ring and top cover ??? was on mine and I had oil everywhere and thought damn the housings cracked, got a new ring and cap, fine ever since, $10.00 and 5minutes,oil loss when you take the old cap off 1/2 cup.

hey check out my old post "oil filter housing leak-HELP!" I think I had the same problem. Its not a hard DIY...the belts and alternator and fan need to come off, I think the filter box too. But the filter housing justs bolts on. There are 2 pressure plugs on the back side of it that have o-rings...mine wire bad so I replaced them, and voila no more leak. It was really weird that those just randomly went on me and it was a bad leak, but fixed for like $1.50 and an afternoon.

buy a used one and swap er out if the housing is actually bad.

Make sure that the gaskets/copper rings on the bolt that holds the housing lid on are not damaged as well. They will cause leaks if they are damaged.

Good luck.

I would start with checking the lid gasket first though.
