124304, Read my plugs
Posted by 740 turbo brick, Feb-25-09 11:06 AM
Pulled my plugs out today, still trying to find out why its miss firing. They were a little white, but not blistered like they were extremely lean. But plug #2 has what appears to be carbon tracing on it. Ill let you guys decide..

Plugs from left to right are 1 2 3 4.

Also, the plugs are NGK-R BKR6Es. Mr Buscher himself sold 8 of them to me for like $5 at last years shootout. He looked like he was in a hurry to make some cash...

any oil in the plug well? it looks like you're arcing past the plug into the side of the head

I would start with a new plug and some fresh wires.

No oil that I could see. That actually made me feel better because my car will burn oil on occasion and not seeing it built up on the plugs leads me to believe it is in fact my valve seals and not something more serious.

The wires on there now are the MSD 8.5mm "super conductors". I got them used so Im wondering if they are bad. The cylinder that had the arcing going on has white melted parts in the inside of the sparkplug boot. So it was definately missing the plug. Ill have to throw my old set back on and see if anything changes.

I also was testing resistance on stuff for shits and giggles. I dont know if spark plugs have a set resistance, but all of them were the same except for the one that had tracing on it. It was a lot higher than all the rest. Electricity follows the path of least resistance right?

that it does. If the plug has unusually high resistance I would definitely replace that, since the wire was damaged too it's probably a good idea to replace it as well, it might still try to arc past the plug.

Apparently you missed the 3rd pic.
