Well I had been noticing that my filter seemed a little bit dirty but never thought to check the turbo
Yesterday I noticed it had an oil residue which I could of sworn it was perfectly clean with the oem filter 15,000 miles ago
I just picked up and replaced with the napa 6637 part number filter
Do you think my amsoil filter wasn't working so great or would this residue be from a seal within the turbo?
