Bad HeadGasket?

[JJames]

Ok getting tired of throwing more coolant in the car.
For about 2 weeks now the car will every now and then run a little hot I'll stop and pop the hood to see no coolant left in the bottle...

I never see any puddles anywhere I park and have already flushed the system a few times,
and replaced the thermostat..

I do blow smoke but its more black when white...
Lets see just did a compression test results were 145, 150, 140, 150
That a bad HG?

gonna do a pressure test on the cooling system tomarrow...

but would like to hear other ideas on what could be goin on before I go buy all the goodies for a headgasket install.

Compression is good, but do a leak down test or do an oil change and check there's no coolant in the oil. And if you blowing back smoke you're probably too rich.

recently did an oil change less than 500 miles ago and did not notice any coolant in there

then again that was before I started having these issues. Could do another just to check but lookin at the dipstick the oil seems fine. I'll look into a leakdown if I can do it myself and I happen to have the tools around I'll do that if not I'll bring it somewhere

Most major auto shop rent the leakdown test tool and all you need now is a very high pressure air compressor to do the test.
