1994 Isuzu Rodeo Engine cooling Problems

“Engine oil leaks onto top of spark plugs and exhaust manifold. Leaks seem to be most prevelant when the engine is warming up. I've had the entire gasket kit replaced twice. Occasionally there is enough oil accumulation to cause a light smoke to be seen for just a minute and the vehicle has always had an accompanying oil smell. Oil is not leaked into combustion chamber and no oil leaks onto the ground. Problem does not seem to be rectifiable and dealer won't fix the problem without me paying 100% each time. …”

“This is an ongoing degradation of the hydraulic lifter system that will lead to an eventual engine failure. According to Isuzu mechanics, the hydraulic lifter system in the Isuzu v-6 is prone to oil sludge build-up and the premature failure of the engine can only be avoided through the replacement of the hydraulic lifter system. When first diagnosed, the mechanics used a oil cleaner to quiet the valve train. However, after multiple cleanings and switching to synthetic oil as advised by Isuzu the valve knock remains and continues to worsen. …”
