Subject 1995 GMC 5.7 TBI 2wd RCSB
After posting about weak heat in cab, and finding what is the most likely cause, I discovered a coolant leak at the intake manifold, no problem as I found a great write-up on that fix, so I decided to wait on the back flush of heater core until all parts have hit the house related to the intake and do the needed work all at one time, well low and behold now I find a new leak at what appears to be between the cylinder head and block!!! GREAT!! Intake manifold leak is at the front left side, coolant leak for the head/block is on the same side, I'm guessing that I'm not that lucky that this is coming from just the intake? 114k on her and hasn't been monkeyed with, no steam or smell of coolant in exhaust, runs great other than lack of heat in cab(this will be fixed soon), is a head gasket leak in that area common for this year of motor? If not since intake is coming off, pull both heads and new gaskets, if that is the case it "shouldn't" have any "bad" effects on the motor, if the option here is head gaskets, Fel-Pro? OEM? Its just a daily, I just can't believe with 114k on the clock a head gasket has hit its end, guess you win some lose some, any info and or opinions will be greatly appreciated!
