1993 Isuzu Trooper ProblemsValve 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.
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 wiring may be of help it this case.
A severe engine oil leak may be the result of one or more of the camshaft plugs falling out of the cylinder head. The is most likely to occur in cold climates and is caused by the expansion and contraction of the cylinder head. There is a cam plug retaining kit available to secure new cam plugs in place.
