I need some help / opinions. I have an 03 Chevy dually with 215,000 miles. Friday I was driving along and all of a Siddons the coolant temp shot up and it started bellowing white / blue smoke from the tailpipe. I pulled over and shut it down. I checked the oil to see if there was a coolant oil mix but it was so low it didn't read on the stick. So I let it cool off and started it up to pull off the hwy. it ran good and made good oil pressure but still blew a lot of smoke. I slowly drove off the hwy and right before I shut it off I heard a little "pop" and oil started dumping out the back of the motor.
The overheating was caused by a broken heater core quick connector. But I can't figure out why it was blowing smoke / burning oil. I did a compression test today 7 were at 375 and 1 was 325. Now I am going to pull the transmission to see where the oil is coming from.
Any opinions or suggestions? Is 325psi bed enough to burn a lot of oil?
Thanks
Brian
