Does anyone know what the base line compression in Pounds per Sq. inch would be for a 1999 1.8.
My second question. my spark plugs are burning white or close to it maybe a tint of light brown but vary white. Is that good, bad or Ugly. Can it be to hot? The water temp runs about 210 when itís real hot out.
I was two seconds slower at Mid Ohio this weekend, I am hoping its something other than me.
Hum, those don't look good. The spread between 1 , 4 and 2, 3 is pretty big. The test should be done with the car warmed to operating temp and throttle open. If that wasn't the case, do them again. If it was, next you should do a leak down test.
Heading off to WGI tomorrow. Weather is looking good. Hoping to learn the track better and avoid the Blue Bushes. We got 7 onboard. See you guys at VIR in Sept. Let me know what you find out with the car. I hold positive thoughts.

26 psi difference. FSM says 28 max. But I agree with Ralphie. If you are using a Harbor Frieght type leakdown tester it wont give you an accurate reading for the rings. The pressure is so low it probably wont expand the rings.
