| Post subject: | Oil Fouling |
Hello to the most knowledgable engine message board i know of! My '83 truck had been sitting since late november thanks to a defective "remanufactured" dizzy from NAPA, my man D.I. sent a new dizzy and it started right up. i've been working on dialing in the advance and i got some NGK UR5's today, my truck really responded to them and runs and idles much better. i had some Autolite 26's, and i noticed that the old plugs in cylinders 2, 4, 5, and 6 had motor oil on them! maybe that was causing the misfiring and pinging in 2nd and 3rd gear when i floored the pedal. i looked inside the PCV hose and i didn't see a lot of oil. what can cause oil fouling, blown head gasket, bad valves, bad rings? more things then that? |

You could get some oil fouling from the valve stem seals leaking if they were old and the valve guides were a bit worn...You can run a hotter plug like the UR-4 and see if that clears it up (hotter plug can 'burn up' that stuff), but you may need to rework your 'tuning' a bit (fuel, spark)... but this may be a temporary/'farmers' fix for permanent problem... Glad the distributor worked out for you... -D.Idiot |
