Plugs fouling Sign In

I have a 170 ci 6 cylinder in a 63 Ford Falcon that keeps fouling plugs. I remove them and they have a lot of carbon build up as well as a lot of oil. I suspect I have ring issues but do not want the expense of a rebuild. Is there an engine additive that will help this problem?

This gadget is called an anit-fouler for plugs. Plug screw into this and then together back in engine holding the plug's electrodes away from faster direct fouling. THEY WORK!! This is a cover up fix not much more. Do try to stop extra gasoline fouling from a rich mixture. Oil fouling thru worn rings, valves etc will improve with use of like 20-50 weight oil.

This engine should not have a PCV valve but instead a vented oil cap and or tube to ground which must be clear. If there's no vent on the valve cover thru the oil cap or another item then it would cause oil fouling of plugs - it's prehistoric but some parts place should still have a vented oil cap. It should have like steel wool in it so oil doesn't make a mess too fast at the valve cover.

63 Falcon was a fav of mine. Had the 144 six with "three on the tree" -- tough little car of the day,

Thanks--this engine does have a PCV--came out of California. It has a tube connected to the oil cap. So, it seems a rebuild is only "good" fix for the oil burning and resulting fouling?

WinkI stand corrected on the PCV - I thought Calif didn't separate themselves till a few model years later. No matter as they work fine but must work as well or that alone if not operative will cause fouling.

Some basic engine diagnostics will tell where most of the oil is coming from in a worn/older engine. Piston rings and classic "blow-by" would be likely as well as valve guides to valve issues. If oil pressure has been good it might be a reasonable rebuild and I'm sure good "cores" are available. Keep in mind this car shares lots (engine, suspension, underbody, trans etc) with the early Mustangs so parts should be easy for mechanical anythings.

Is this car nice enough to go for it? Would you rather do the best possible to "fake it" for a while? The plug fouling alone can be dealt with for quite some time,
