1999 Isuzu Trooper Problems

Rough idle due to leading intake manifold gasket

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.

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.

Valve Train Noise Due to Varnish Build up

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.
