Help ! Oil in spark plug slot - ZR-1 Net Registry Forums

dlgeary · 09-15-2006

I need some help from the experts!

I am a new owner of a 94 ZR1 (6 Months) and last night when I was changing spark plugs, the #5 cyl spark plug was covered with oil on the outside. I pulled the boot and oil dripped out of it and when I pulled the plug it was tight and looked the same at the other ones but with oil on the outside. All other plugs were fine.

The car has been running fine. I suspected the crank case vent that enters the plennem just above this plug, and checked the PCV valves but they were fine. There are no visible signs of oil.

Where do I start looking?
