The 4.2L Trailblazer was brought in for suspected bad alternator, but Eric discovers low compression on cylinder 6, and leakdown test shows it's the intake valve. The trailblazer has 180k miles. What causes this to happen, and what can I do to prevent it from happening to my 2008 TB 4.2L?
Saw in a South Main Auto vid, a trailblazer with bad intake valve on cylinder 6.
