I have a 98 Burb,319,000 miles on it. I am losing a lot of coolant lately and of course it is in the oil. If the block is cracked wouldn't it overfill the oil pan. It is obviously burning coolant, I can smell it and see it. This leads me to think it is a head gasket or intake gasket problem. When I hit the throttle hard I can hear what sounds like the valves tapping, I am also having transmission problems and the tranny guy said I need to fix the engine first to make sure the transmission problem isn't engine related. It will not shift into overdrive or final gear whatever you might call it. It puts out quite a bit of engine noise at 2000 rpm on the highway at 60 mph. If I tear this thing down to rebuild I am concerned about the block. With the history of block cracking it worries me that I could do the rebuild and have the block crack anyway, does the girdle kit stop the block from cracking. I am also considering 18-1 pistons on the rebuild but I have been told this will make the engine even louder that stock. I live in Missouri and understand the cold start issue. What should I do, do you have any better ideas.
