Re: Spark plug diagnosis
It's back. 13,000 miles and #4 and #5 are fouling again and it's not electrodes melting.
My guess is that since it is cylinder specific, I have stem seals going TU on these two cylinders. The good part is that it's easy enough to do on these two. The bad part is that we have all hands on deck right now and I can't see any downtime that won't entail me working on this on the weekend. Oh well, that's what they pay me minimum wage for.
Do these engines even have replaceable stem seals? I am just guessing and if they don't, that means the guides are wacked. I guess all gassers have to have stem seals since they SUCK so much. :)
Anyway, has anyone tackled this on a 3.3? How was it? What do I need, just stem seals and a valve cover gasket?
Oh yeah... and a PCV heater since somedog that I won't mention broke this one.
