Diagnosing head gasket failure OR something else?
Just my luck. I'm in the midst of diagnosing head gasket failure. Went to work last night, seen some smoke in the mirror and pulled over, smoke just a rolling (hasn't overheated at this point). Since I know the radiator isnt that great, i went ahead and turned the heat on full to get the heat out from the motor, and i got no heat! So I turn truck off, check the radiator, its low obviously, put in what coolant I had, half a jug maybe. Seen a lot of smoke come from the exhaust flange gasket, bolts were gone. weird but whatever. So i figure the smoke was coming from a toasty felpro gasket. took it to work, no overheating, came home, no overheating, still smoked. Picked up a new gasket put it on, still smoking. So....What Have I got so far.
Lots of white smoke indicating burning water.
no overheating. slightly went past the op temp but came back down to op temp.
Hesitation upon idle/take off. runs fine getting up to and at speed
Oil is NOT milky. However, I did see very small rubber pieces on the dipstick.
Whats next. Compression test. I will post results with-in the hour. Pretty discouraged at the moment though. Had it running great other than the low oil pressure problem. But I don't see the two being directly involved. However, while I was under the truck messing with the new flange gasket i did noticed some oil on the bell housing, not a lot like before the rear seal repair.
