90V6RedHotLuminaEuro Posted November 4, 2011 Report Posted November 4, 2011 My Best to All... How Do You Do A Compression Test on a 3.1/V6? What is the correct method to get accurate readings... and what readings/numbers should one get from a healthy engine? John B. Quote
Mater Posted November 4, 2011 Report Posted November 4, 2011 take out all the plugs. hold the throttle fully open and crank the engine over 5 revolutions. easier to do this with a helper all readings should be above 100psi and with in 10% of each others the reading should be close to 160psi Quote
