Diagnose these plugs please!
Diagnose these plugs please! So the first pic is from cylinders 1-6, and 8. They all look the exact same.
The second plug is from cylinder 7, it seems that their is oil on the end of the threads and about 1/2 the way up the part where it arcs.
Motor - 94 z28 with a 355 LT1. Bored .030 over, CAi, exhaust, installing Longtubes now, 1.6rr, hotcam. 1500 miles on the motor since rebuild.
