Stumble in engine & strange plug readings

red70racer · 8/21/12, 8:02 AM

I'm throwing this out here to see if anyone has had this same issue, after a red Saturday night the car never would clean out with a stumble. It was running flawlessly up to red with temp under 200 when red came out Pulled plugs Sunday morning and 1 3 5 7 were wet, 2 4 6 8 were completely dry and looked perfect.
I had a guy tell me he had a arm on the butterfly shaft slip once causing my issue, however that wasn't the case
I've done all the normal checking by-passes, fuel vent, return lines etc.
Anyone heard of something like this before?

Sounds more ignition related to me, if I saw plugs that were wet on one bank only, I'd ck some wiring in your ignition system, sounds like you've done the prelim ck's on the injection. JMHO! Bob

****** Sucked the intake gasket in, seems the cork ends were holding the plenum off the heads glad it was something simple*********

Mystery solved, it is oil, got something leaking in the head, 2nd night out with brand new heads, got them at machine shop now
