non-fouling extensions

Ok,,question,,,,,I have two plugs fouling out on my 350 engine. Not really that bad,,,but I clean them every so often. Would non-foul extensions help this?

Re: non-fouling extensions

It will work for a while. Remember it's not fixing the problem. Are you getting oil on the plugs? If so it's a ring problem.

Re: non-fouling extensions

I know this is an old thread, but, here is what I have experienced. If you are having oil fouled plugs in two adjoining cylinders, it is most likely a bad head gasket, is the two plugs that are fouling #6 and #8 cylinders by chance? I was told by a mechanic that it is common for this to happen on these cylinders....
