Oil Filter Housing Gasket? Need confirmation

1) Is this a typical drip pattern for an oil filter housing gasket leak?
2) Is there any other possible leak source I should review?



There was a small spot of oil on the driver's side lower shield, directly under the front differential housing. The diff fill and drain plugs are not leaking, nor is the drive axle seal leaking. Also the power steering hoses and fittings all appear dry.

The area shown in the pic below was clean and dry 1500 miles ago. There is a little oil on the front oil pan casting which makes me think the oil filter housing gasket has started to degrade. Yes?

That's what mine looked like. I just did a marathon day of OFHG and VCG replacement. The OFHG looked like it was leaking like a sieve once i got everything off. Hopefully this fixes my oil leaks.

Thx Schloe. I also ordered parts for the CCV Oil Separator. Since the alternator is off and the PS pump pulled to the side, I'll swap out the CCV. The car has 96K, so I may as well get it done now before Chewbakka starts growling.

My front diff was soaked with oil. I replace the housing gasket and its much cleaner now.

It really didn't take too long. I didn't take everything all the way off the be parts cleaned like some do. It was more of a pop it loose, swap it out and slap it back together. Took a couple or few hoists including removing the belts etc.

As a matter of followup to my original post; the leak was indeed sourced to the OFGH. I won't bother posting a pic because it looked exactly like all the others with oil settled into the waffle-like recesses of the engine block. The rubber seal was intact with no broken sections; however it was considerably flattened compared to the new seal. I guess as the seal ages, it begins to shrink or lose elasticity to the point where oil pressure forces a leak. In my case a rather small one, but still enough to collect on the splash shield below.

Should have also replaced the Valve Cover Gasket

After replacing both the Oil Filter Housing Gasket and CCV, I thought the smoking would be fixed; but it turns out there is still a little smoke emanating from the passenger side bell housing area. Probably the valve cover gasket dripping back onto the exhaust pipe or cat. There are no visible signs, e.g., stains on the exhaust heat shielding; I can get a little oil on my finger tips when I feel along the under edge near the O2 sensor harness. Live and learn. If you have one leak... fix 'em all. Gordo

What you describe was exactly what I had... And the smell... Once, maybe twice, per day... An acrid smell of smoke. Changing the VCG stopped it. An easy 1-2 hour job depending on how hard your VCG and accompanying gaskets are frozen on. Mine were like bakelite... The gasket clean-up took me an hour out of the 2 hour job.

VCG beware...

Just did the VCG today on my '05 330i. Started by draining the oil since it was due for a change anyway and the wind kicked up and sprayed oil all over the driveway
After I cleaned that up, replaced the VCG and while torquing my last nut, the stud snapped off in the head
Going to pick up a new valve cover stud and nut, then coming home to REDO the original VCG job. Awesome... I've done a ton of jobs on this car and this is easily the most frustrating (when I thought it would be so simple...)
Hope your VCG job is more fun than mine!
