before or after it was run. i've got a little more than an hour of idle time to try and burn this "condensation" out and its dumping tons of smoke. i've had condensation before from sitting for a month and it took 10mins to burn it out

take a video....

the head gaskets on H and F motors usually SEEP after the car is shut off when the cooling system is pressurized, so first thing in the morning you'll get a rough/low idle from the misfire caused by incomplete spark due to coolant in the cylinder/s.

if you have a pressure tester for the cooling system its easy to test. with the motor COLD hook the pressure tester to the radiator and pump it up to about 5psi, crank the car, if its got a blown head gasket the pressure will jump up instanly.

there is honestly way too many things that could cause your idle problem and smoke but without actually looking at the car nobody can really diagnose it.

Yeah the idle looks like it just needs a tune. Just waiting for this combustion leak tester to come in then i'll go from there

l I hope you get it all fixed up. :mrgreen: That engine sure is CUTE :mrgreen:

combustion leak test came up clean o.O

Do a seafoam treatment and see if it helps.

That's like putting stop leak in a bad transmission, it never works.

Worked for me before.

...and my Yukon drives better when its clean.

Cool story bro.
