Geo ProblemsEngine Oil Leak From Front Crankshaft Seal
An engine oil leak may develop from the front crankshaft seal due to hardening of the rubber seal. There is a revised seal and sleeve available to correct this concern. Our technicians tell us that changing the oil every 3000 miles may help prolong seal life.
Illumination of the Check Engine Light can be caused by a loose or worn gas cap.
The EGR System tends to get restricted or blocked with carbon after 100,000- 125,000 miles which will cause an emissions test failure for NOX. If the EGR system is equipped with an EGR temperature sensor it will trigger a Check Engine Light for improper EGR flow. The repair is to clean out the EGR passages and the EGR Temperature sensor. Our technicians tell this repair is pretty straight forward and takes about 1-1.5 hours. It is also wise to verify the EGR system components i.e. the Transducer, EGR Valve and VSV Solenoid at this time.
