A ticking noise may be noted from the engine valve train area. This is commonly caused by varnish build up in the hydraulic lash adjusters (HLA). Our technicians tell us that using Mobil 1 synthetic oil has been successful in cleaning the varnish deposits and quieting the lifter noise.

Isuzu Trooper Problems
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.
The check transmission light may illuminate with a stored code 37. This is commonly caused by electrical interference on the data communication circuit between the transmission control module (TCM) and the engine control module (ECM). Our technicians recommend that all related connection and ground locations should be inspected and repaired as necessary. In some cases electromagnetic interference may be the cause, shielding of the affected wir...
A rough idle may develop which may or may not cause the Check Engine Light to come on. This issue is commonly caused by a failed intake manifold gasket which will require replacement.
The fuel level sensor may fail causing erratic operation of the fuel gauge. Our technicians tell us that replacement of the failed sensor is necessary to correct this concern.

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.
Transmission: after having the car stuck at the machine shop (doing some valve head repairs) which extended for over three months, I've noticed my transmission hesitating when starting (seems like clutch slippage). Wonder (hope) this is due to machine being down for so long. Next steps, check oil level, if ok, run car for over 1-2 hours to see if after warming up problem gets eliminated. Open to hear any expert advice. Best to all!
I BOUGHT THIS TRUCK FOR 700.00 NOT KNOWING THE PROBLEMS I WILL FACE. I HAVE PUT OVER 300.00 AND STILL NOT WOKING LIKE I WANT IT TO BUT I STILL HAVE FAITH THAT I MADE A GOOD CHOICE. IF YOU WANT A TRUCK THAT WILL TEST YOUR MECANICAL SKILLS THEN THIS IS THE TRUCK FOR YOU.
