Known 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.

Some engines may develop an oil leak at the front of the engine, the source is commonly the front crankshaft oil seal. Our technicians tell us a revised front oil seal retainer gasket is available to correct this concern.
