Header primary tubes on cylinders 2 and 4 have some strange discoloration on the header tubes. very close to where the plug wires are. I have angled ceramic plug boots on all other wires but it was too tight on these cylinders, so I used regular firecore rubber boot 90 deg wires.
Never seen this before today, but did run the car a lot the last couple days. I started to notice a bit of a low idle towards the end of my last drive, possibly a misfire. I’m waiting for it to cool down now before I pull the plugs and inspect further.
You can see a white patch on the primary tube. Headers are steel with some VHT header paint.
Could the plug wire be arcing?
