They guy i bought it from said that about every 600 miles u have to change the plugs becasue oil is fouling the plug.i drove it from Minnesota to kansas which is about 700 miles and i havent notice anything. the check engine light was on when i bought it i check it and it was #8 cylinder misfire so i thinking with 7 fouling out its making 8 foul to but i havent notices any oil burning but i have only drove it one day so i just askin for ideas on oil being on the plugs casue obiviously it burnin enough to foul the plug. any ideas

bad valve seals? worn piston rings?

do a compression check and you'll find your culprit.

change the oil and filter, put lucas additive in it, and drive it, see what happens. Autolight plugs are good for oil burners, they don't foul as fast

PCV valve could be bad... beleive it or not. could cause excessive oil to be pushed down the vavle stems or past the rings. cheap fix

YES stumpuller is big times correct I have seen it happen on a dodge car. Might give it a good tune up with quality parts meaning not from Auto Zone.

Intake manifold plenum gasket. Very very big/common problem with 318/360

daville_pits · 12-22-2008, 08:26 PM

ok the truck has so 109,000 miles runs good but you have to replace the plug ever 500 miles or so..... the guy i bought said it was the intake gasket but how do u know for sure dont wanna be a parts thrower lol so any ideas are good thanks

daville_pits · 12-22-2008, 08:28 PM

and what should the compression be??? roughly

mudseeker · 12-22-2008, 08:40 PM

well, my compression is around 170 with one cylinder at 115. as long as they are all around the same, you should be ok. you could also rent the tool at autozone and do a leak down test too.
