I have a 1994 Isuzu Trooper with a 3.2L gasoline, 24-valve, V6, DOHV, about 280,000 km = 175,000 miles.
The truck was neglected for a while and developed a “tick” sound in the engine. I’ve given it 2 half-can treatments of Sea Foam so far and it’s much quieter. How often should I repeat the treatment to stop the tick noise? Do you think it will continue to improve? What is Sea Foam – is it primarily a detergent?
