Crankcase blowby thru oil filler on superchrged AP1
Hi,
I have a 03 AP1 with a SOS supercharger and I noticed that at idle I have a significant amount of air coming out of the oil filler with the cap off. I pulled off the vent line and the pcv valve, and a strong stream of air comes out of all of the holes at idle. I also smell oil after a full throttle run. Is this normal? Possible broken rings/scored cylinder?
Thanks!

Yes it is normal to have air coming through the ports in the valve cover. The difference is how much air and if it's enough to show a sign of trouble with the bottom end. Chances are you're fine, but do a compression test and/or leakdown if you're unsure.
