Good Morning Mopar Misfits!!!!
No, he has changed the plugs (tried hotter to burn it off), swapped wires and distributor caps. Strange for it to only be right on the electrode and ground strap. If oil I would think it would be covering the plug more, but it is super clean.Eric, No idea what happened to that plug. Was it hit on grease going in and burned most of it off? New one on me.
you test that by holding the coil wire while turning the motor over don't you?What coil voltage output is he using?
Happens every time after a bit of runningso twice it happened?
LOL Reminded me of manual timing light. Every time the plug wire shocks you flash the flashlight.you test that by holding the coil wire while turning the motor over don't you?
All I know is it is a later model Pertronix multispark distributor and coil. Maybe he will chime in for more details.What coil voltage output is he using?
Yes, while standing in wateryou test that by holding the coil wire while turning the motor over don't you?
You far from Racine Wi?All I know is it is a later model Pertronix multispark distributor and coil. Maybe he will chime in for more details.
About an hour to 90 minYou far from Racine Wi?
I've seen similar before. Valve covers on Fords 2.8 and 2.9 V6 leaked bad. Tip of plug might drag through the sludge build up when going toward the hole.@Mattax @halifaxhops
Anyone know what would cause this type of carbon bridging on one of Dads plugs? The rest of the plug looks damn near unused

A guy I deal with pretty sure he has a scope.About an hour to 90 min
This is a brand new build. There really shouldn't be any leaks. He will likely see this conversation and can check. ThanksI've seen similar before. Valve covers on Fords 2.8 and 2.9 V6 leaked bad. Tip of plug might drag through the sludge build up when going toward the hole.
Definitely different. On two sets also.This is a brand new build. There really shouldn't be any leaks. He will likely see this conversation and can check. Thanks
By chance you have a cylinder kill meter? Or just go old school and take the wire off when running and see if there is a RPM drop, if no change prob something mechanically is broken. If it is sparking.@Just Ron
Another issue that may or may not be related. The PCV valve rattles.....
So, talking this over here at work, we had a discussion about a bad ring/broken ring/up side down ring possibility. The thought was oil is getting into the chamber and fouling the plug...the cylinder then no longer fires and gas washes the plug clean except where the electrode and ground strap are partially guarded from incoming fuel...explains the oily residue in the exhaust pipe also. At higher RPM maybe the cylinder works...unsure. The rattle from the PCV valve could be combustion pressure getting into the crankcase....rattle (due to pressure change) each time that cylinder comes up.
Nice work, it will be much better soon.Good morning coffee crew! I was up early as usual and out cleaning up from demo yesterday on the front porch. He got here at 6:15 this morning to get to work. Good thing we are replacing it, a lot more water damage to the wood then could be seen before ripping everything out. Combination of gutters done wrong and the flashing not being correct lots of rotted wood. I know it will be done right now and we will have a great new front porch.
And unfortunately no coffee for me until after getting my blood work done at 9:45am. I have my yearly physical next week so just routine. Also dentist appointment at noon, busy day running around.
Another thought, yes. Cylinder drop test. He can run it at idle, and pull plug wires at the distributor.By chance you have a cylinder kill meter?
