Wow my LS has been having some trouble lately...

^^^^^ Makes a lot of sense, because when i took the head off the motor, i noticed that the cylinders were bascially flooded with coolant as well....

Yeah. That's BAD buddy. That's REAL bad. If all four had coolant in them then you seriously need to consider where that's coming from. Take a straightedge and lay it across the top of the block and push down. If it does not perfectly lay along the top of the block, you have probably found the source of the coolant. Check the bottom of the head too, as it can warp as well. If it's not major, consider having the block top/head bottom machined down to where they're even, but I won't guarantee that's a fix to your whole problem. If we're talking about floods of coolant, you might have a crack, or who the hell knows.


Blue smoke is oil, which indicates a different problem. That's probably the ring seals or valve stems. O_o

My new suggestion to you: Source a new LS motor. Or a GSR motor.
