Unhappy 08 OBS oil issues

About a month and a half ago I noticed the smell of burning oil coming from under the hood of my 08 OBS with 86k miles. When I got home I saw oil dripping, 1 drop every 20-30 seconds at idle, but the underside of the engine was covered. The drips were coming from the bottom of the oil pump. I drove it another week and the oil smell got worse and so did the amount of oil it used(about a quart that week). Being scared of a fire or blown motor I parked the car and let it sit. Since it never got above freezing since early February I took my wife's car. This week I pulled the timing belt cover and got down to the oil pump to inspect it and found the front main seal 1/3 of the way out and scraping on the back of the crank sprocket. I replaced it with a new on and put it all back together. After I drove the car for 15 minutes or so I got home and look and it was still dripping.

I noticed another oil related issue also. When I checked the oil level originally it was right between the 2 marks. I check it a day later after driving but cool and it was way up the dipstick. The other day when I checked it was normal, I drove it and let it cool and it was normal. Then yesterday I drove it and let it cool and it was way up the dipstick again.

Today I decided to change the PCV valve figuring that may be clogged and causing excessive crank case pressure. It wasn't but I changed it anyway. I'm at my whits end. If I don't figure it out soon It's going to the shop and I hate doing that.

HELP!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!

'08 2.5i hatch


I have the same oil leak issue with my 08 2.5i. I took off the timing belt cover and appears the leak is coming from the oil pump area. I didn't take anything else apart yet (been too busy) but I plan on looking at the front oil seal and then taking off the oil pump and looking at the front main seal.

Since you replaced oil pump seal, maybe the oil pump relief valve is not working properly.
