Just did a compression test

[pr0]

Results were as follows:

180-185-190-185

It this good? I though I was burning oil but its actually stopped smoking blue and its more white and clear now.

95 N/T

I'm not sure what N/T compression figures should be, but in any engine they are supposed to be within 5-10psi of each other, preferably 5. As for the smoke, white smoke means burning water/coolant. Check your oil for coolant and your coolant for oil.

no its 20%... those look just over the"id start to worry" limits. You say your blowing white? If you are at all temps then your burning coolant and the only reason your compression is up like that is because of carbon deposits. Do a cylinderleakdown test and see how long it take to leak pressure....

the Safe zone is 170-220, my eclipse nt ran 211, 211, 186, 205. You sound fine throw some engine restore in you should gain back some pressure.
