^ *Engine that is. Did u notice i only have 30k miles on this engine? Not just rebuilt, like someone on this forum previously stated remanufactured by jasper.
That been said. Since if this were a bhg issue i would be having cooling system issues. And im not. In any way shape or form. Then this is def rings/valve related. Also, with number like this shouldnt the car ooooo i dont know NOT RUN? Well this isnt the case. It runs fine. On cold start it takes about 2 seconds of cranking to get started, but after it warms up it idles and runs basically normal. Kinda has me wondering if maybe the valves are gummed up to the point where im losing compression in those other cylenders. I think i might try and throw the engine back together and run like an entire bottle of carb cleaner into the intake while the engine is running. See if that clears things up a bit. Also if it were my rings, id immagine the number would be a little more consistant. Here i have 2 cylenders dangerously low, 2 well below par, one a little below normal, and one perfectly normal if not really good. If there was ring falure its unlikely to happen in 4 cylenders. If there was excesive ring wear then the numbers would be more consitant. BUT if i were to say have stuck valves from carbon build up. Any numbers are game.
Either way. Im not rebuilding a damn thing! Do we know why? Oh yea. Its still under warrenty! Ill let jasper deal with it from here. Unless anyone else thinks the valves sticking sounds like a possiblilty. I also have pics of the top of the head and spark plugs that ill post up tomorrow morning.
