Stock oil bath air cleaner or aftermarket?

[911pickup]

I took the engine out so I could send the tranny off for a rebuild. Not sure why, but the side of the engine compartment that had the oil bath filter was covered in a layer of oil that had, I'm guessing, come from the filter over the years.

I have a cheap aftermarket air cleaner and installed that when I put the engine back in, but I'm having second thoughts. I'm wondering if I should put the stock oil bath air cleaner back in.
Would there be an benefit to having the stock air filter kit in place, over the aftermarket filter?

Also, I'm wondering if anyone else had the oil bath filter system deposit oil in the engine compartment.

The oil bath canister gasket doesn't seem to seal as well with age. Never checked to see if they were available new somewhere. I just wipe the side of the engine compartment down whenever I remove the air cleaner for service.

For myself I don't like running without preheated air as doing so slows warm up and hurts gas mileage.

My canister leaks oil too. As Wildthings said, the old gasket must not seal as well as it did when it was new.

The stock oil bath air cleaner filters better and is quieter.

Other than filtering good, the oil bath seems to quiet down the engine noise a lot.

I've run both, driving without the oil bath I had to holler at my rider,
with the oil bath, you can just talk loud.

Never measured the db level but it was a big difference.

Stock oil bath filter also does a better job FILTERING. Just use the stock filter if you can - those VW Engineers knew what they were doing 😎 ✌ PS Happy Father's Day to all you Samba Dads!!
