1990 Isuzu Trooper Problems

Excessive Engine Oil Consumption

Lack of oil changes can cause the piston rings to become clogged with debris resulting in excess oil consumption. Severe engine damage may result if the oil level gets to low. Engine dis-assembly may be required to clean or replace the piston rings. Our technicians recommend proper maintenance to try and avoid this expensive repair.

Engine Oil Leak From Front Crankshaft Seal

Some engines may develop an oil leak at the front of the engine, the source is commonly the front crankshaft oil seal. Our technicians tell us a revised front oil seal retainer gasket is available to correct this concern.

1990 Isuzu Trooper Reviews

It's a great vehicle!! Enjoying my 1990 Trooper since 1992. Highways, off road, daily driver, anything mover, etc... Over 250,000 miles on it. No problems ever with the auto transmission. The 2.6 liters, four cylinder engine is an excellent engine.
Best vehicle I've ever owned or driven. Perfect for work, family or play!! Turns on a dime and hits off road perfectly
