Im searching for your Experienced opinions.....


My car hasnt been running too well lately, and I have also been noticing my coolant levels have been sneaking out on me.

Here is the info

Compression test reveals:
#1 Cylinder: 170 psi
#2 Cylinder: 150 psi
#3 Cylinder: 140 psi
#4 Cylinder: 180 psi

Leakdown test reveals:
#1 Cylinder: Slight leak from Intake mani
#2 Cylinder: Mostly from valve cover (removed oil cap)
#3 Cylinder: Stong leak from Intake mani & Cylinder #4
#4 Cylinder: Slight leak from Intake mani and Cylinder #3 (When "leak" in said, It is not a gasket leak....Air was rushing threw intake track)

No coolant mixed with the oil
No oil mixed with the coolant
No boubling from coolant with leakdown test
No overheating since t-stat replacement 3 weeks ago...

Im thinking bad HG and burnt/or damaged Intake valves, But dont know where my coolant is going unless its going directly into the cylinders and being burnt but no smoke, But I have noticed a coolant smell while the car is idleing, not while driving.

Are your ideas the same as mine? Whats your input? I was planning on doing a head soon anyway, just may come sooner then expected.....

i would tend to lean towrds a bad head gasket as the cause of you coolant leak. does it start hard or idle or idle roung when you first start it each day or after it sits for a while? Also a burnt exhaust valve will create masive power losses and could be the cause of you low compression. if you decicde to replace the head gasket it would not be a bad idea to check the head out while you have it off
