Hey, looking for any ideas on how to keep my plugs from getting oil fouled. Ive tried anti foulers, but makes it run terrible. I know it is in desperate need of a rebuild/new motor, as it wiped out the cam lobe for the fuel pump. It doesn't have low compression, and the valve stem seals were still healthy when I went to replace them. Just trying to limp it by until after the holidays so I can rebuild it. And help it appreciated
 
Not many quick/easy cures for a worn out engine, but hotter plugs may help bridge the gap until the holidays.
What ignition system: Stock, DSII, other? If it's DSII or something after-market, you could open the gap a bit, too.
Plug pics?
 
I would have thought if fouled plugs were a problem, hotter plug yes, but a closer gap than 40-45. Spark will take the path of least resistance. The resistance is less the shorter the gap, and the more it is fouled the lower the resistance for the spark to short to ground. Keeping the gap .025 to .030 would help keep the spark going from electrode to electrode rather than straight to ground
 
Pics of the fouling would help with suggestions and diagnosis. Is it oil, fuel/carbon, ash? Rich fouling (sticky choke, short trips) is more common than oil fouling (worn out rings, valve stems). If your compression is fine...
Agree that less gap = less resistance. But with a DSII or after-market ignition, you should have enough spark energy to open the gaps a bit for a hotter spark. Shunting to ground will happen when the plugs are fully fouled, but hotter plugs + hotter spark would delay gap bridging. Maybe get a few more weeks between yanking the plugs to clean or replace.
