Unfortunately, there is no definitive way to tell for certain if the broken motor mount was caused by the rear-end impact. It may have been possible in an extreme situation, but again, it would be hard to prove. If there...

The EGR valve itself is pressure regulated, and needs...

You will need to have the computer checked for codes since a leaking in the fuel vapor system can cause the vehicle to think the cap is leaking. You may have a bad or leaking vapor vent or purge valve....

Hi John. Thanks for contacting us today. Oil in front of the motor, near the crankshaft pulley, is often from the front crankshaft seal. Although this is not normal, it is common with an engine 20 years old. I'm not...
