1999 Isuzu Trooper Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 1999 Isuzu Trooper

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.

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 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.

I need a piece of the linkage. It's a plastic arm about 2-2 1/2" long with clips on both ends. Since parts are no longer in production anyone know where I can get a used one? Where do other Isuzu owners get their parts?
