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 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.
