spark plug non-fouler

I have been using for a long time this non-fouler devices in 3 cylinders of my C-30 work truck, the engine is a stock 350 wich works fine, but was fouling this 3 plugs, after I installed this gadgets the problem dissapeared, But I still wonder if they don't harm the motor or the performance in any way?
Any experiences or comments?

Augusto

Augusto,

I used these little items a few years back on the back cylinders of my V8 chevy engine. Why only the back two was because the "drain back" holes at the back of the engine had become clogged. Then oil would be pumped up the push rod tubes and feed oil to the rocker arms, just like it was engineered to do. But with the drains clogged the level of oil would rise under the valve covers until the oil would be sucked down the intake valve, past the seal and into the #8 and #7 cylinders, causing them to foul out. I knew when it had fouled the spark plugs because the truck would BUCK and backfire. Buying new plugs got to be very costly so I installed the anti foul thingies and no more problems "for awhile". As time went on the drain back issue became more and more of a problem. I ended up building a new engine and taking that one out, heads and all.

I liked the anti-fouling adaptors. They caused no problem and the engine ran just fine. They allowed me to keep driving my truck until I finished the new engine.

When I took the old engine apart I found bad valve guide seals, bad valve guides and a BIG build up of sludge. I ran the truck without a thermostat and with Penzoil and I believe this combonation caused the sludge.

Good Luck
Scholman

Thanks Sholman for your comments, I will leave them in place until I get the time and money to rebuild the motor but I'm gonna look under the valve covers to see if the drain holes are clear.

I appreciate your help.

Augusto.
