I finished the job in about 3 hours and it solved the leak. The parts in those photos look very familiar. The old gasket was plasticized and came off in chunks. Very happy to be rid of my oil drips now.

Housing rubber gaskets are a very common leakage, fairly simple to do.

Hi. I'm a newbie and I have the same problem. Leak is obviously coming between the oil filter housing and engine block but not much. Say a small drop a day. This occurred when I changed my oil to Mobil 5W-50 fully synthetic. Can it be a reason because of low viscousity? or my gasket is starting to wear off?

Do a search for oil housing gasket. I replaced mine 2 months ago and wrote a step by step. The gasket was shot. Cost was about $7 and 2 hours of work. The stealer was going to charge $700. Why of course!!!! It was a pretty simple job!

I replaced my gasket and now no leaks................good write up. This is a medium difficulty job just because of the layers of stuff you have to remove and reinstall to get to the gasket. Very "doable" though for those who are used to performing their own maintenance tasks (water pump, spark plugs, belts, etc).

you guys are a lot of help. i have a viscous oil leak (my own fault im sure) and i am just about to try to locate it. i thought it was the oil pressure switch but this may be a likely candidate as well,

just a question before i go look for myself, do you guys pull the aggregate from the top or drop it? to get to it from the top i need to remove my sc and to remove that i need to remove a whole bunch of other stuff.... pita.

The oil housing removes from the side then through the air box area. Hope this helps!

I just found a little oil leak too... Haven't had time to track it down, but I hope this is where it's from. Sounds to be a common problem... My car just turned 140,000 miles!!!

If you see oil pooling up right under the intake manifold behind the oil pressure switch (which then runs down the side of the engine block) then this is a likely root cause (especially with your mileage).

Oil Leak

Hi I have read the messages re oil leak from the oil filter housing which are helpful as the garage I went to suggested that the housing had to be replaced as the alloy casing warps and changing the gasket alone is not enough . A housing from BMW costs 250 +100 labour to change. Have you heard of the housing warping before?

Thanks Roger from Bexley, UK

Haven't heard of one...and the diy isn't bad at all...you'll find one, but read many if you're going to diy. Otherwise, maybe an hour for someone who's done a few...$10 gasket...

BTW, at the same time...great time to replace vanos oil line coming off of the housing...you'll need four crush washers with that.

...and if you were diying, and into it...keep going to clean icv/disa,maf, tb and replace all rubber behind those things...maybe some nice heating/engine cooling hoses?

Oh, you'll be removing the alternator and moving PS pump to the side, so anything you want to do with them...as in rebuild alt or flush ps fluid from pump...a few things that are efficient to do with ofh gasket.

Sorry! I actually didn't do alt rebuild, but that is on my list of things I know I'll need to do eventually.

PS, 100 pounds for labor...that sounds like maybe a couple hours of work...and doesn't seem unreasonable, but I'm sure they make money on parts...and I honestly do not recall reading anything about that...but do a search here.

(any acronyms confuse you coz you're brand new here...just search, you'll find the answer...and read thread on searching too....right above you!)

hahahaha i need to show my dad this thread. he was in my car the other day and i told him that i had this problem happen to me and it was just the o-ring in the oil filter cover that needed replacing.

he proceeded to yell at me for the rest of the ride about how wrong i was, how he's never heard of an oil filter cover that had an o-ring or needed to be tightened with a wrench, how he's done hundreds of oil changes in his life so he knows he's right and i'm wrong, how i don't know what i'm talking about, how it's probably a serious problem that is going to cost me thousands of dollars, etc.

Carsos, just open the hood and show him the filter housing, and better yet, show him a replacement filter element.

Rogerbest, I replaced the rubber gasket between the block and filter housing about 40K miles ago, and it's still bone dry. I'd guess my casting was not warped, and yours is likely not warped, either. The leak is caused by the rubber becoming hard and brittle. You will see just how brittle when you remove it.
