Oil Leak
Anyone ever have issues with their oil filter cap leaking oil? Mine is very slight but still enough to give that burnt oil smell when I slow down. I was thinking of just ordering a new aluminum cap with O ring but just thought I would ask and see if anyone has a simple fix. (I'm currently running the OEM cap)

I've only seen it on cars that had pretty old o-rings and such. You could try a new cap, it might have a small hairline crack in it that's hard to see.

I would guess you've got another leak causing your burnt oil smell. I don't think anything in the vicinity of your filter gets hot enough to burn oil, unless it's a large leak.

What filter did you get? How many pounds of torque did you apply to the cap upon install? Did you replace the old O-ring and apply some oil to the new one prior to install? |
