Saturn SC2 Burnt Valve- Leakdown Test

Although not related to offroad, we all have a daily driver! Check out how you can diagnose some engine trouble with a leak-down and compression test. This is a fairly common problem with the Saturn S-Series DOHC engines if not taken care of properly.
The cylinder 3 burnt valve can happen for a variety of reasons, but most likely from a lean mixture due to low fuel pressure. This can usually be avoided by replacing the fuel filter regularly and cleaning the fuel injectors.
