anyone had issues with aftermarket oil filters?
My last oil change, I used a Wix oil filter. Previously, I had always used OEM filters from the dealer parts counter. Today at lunch, I fired up the car and noticed a slight knocking sound for 2 to 3 seconds (identical to the sound you get at first start after doing an oil/filter change). Didn't think much of it. Car ran fine when I drove away.
When I got back from lunch, I saw a trail of motor oil on the ground behind my car. Let the car sit for 5 minutes, then checked the oil. It was exactly at the low mark on the dipstick. I had just checked the oil on Sunday, at it had been at the full mark, so this means the car has leaked about a quart of oil in 3 days. Looks like the leak is coming from the oil filter housing area, possibly where the housing connects to the engine underneath the intake plenum.
Anyone know if this leak can be caused by the Wix filter? Maybe an overpressure in the housing, leading to oil blowing by the housing gasket at the engine block? I'm gonna run down to the dealer and get an OEM gasket in the morning. Hopefully this fixes the issue, otherwise the labor would be pretty intensive getting to the leaking gasket.
