    Hello All!

    my 80 sd33t only has about 2-3k miles on the shortblock, and there was compression leaking out the side of the headgasket at speeds/loads greater than 45mph. I took the head off to investigate and definitely found a narrow channel where combustion gases were leaking out the side of the gasket from around one of the small coolant holes (jug 2), but i dont see any real damage around the piston sealing rings - except that around cylinders 2,3,4,5 all have a fair bit of carbon/soot around/between all those cylinders especially moreso on the drivers side of the block - see pics and let me know if you think this was just improper torqueing or lack of re-torqueing or what you think the possibility is. I pretty much purchased this truck this way, ive only put about 20 miles on it total since i got it a couple years ago.

    thanks for your help!
