I'll try to keep this as coherent as possible. A while back I had my car on the dyno, after a few pulls we let it cool down. After starting it up after the break it began blowing white smoke. Everything in the engine bay would get work REALLY fast. Even my intake manifold would became skin burning hot after 5 minutes at idle. Well I pulled the head off yesterday and started looking. The HG (its the Mitsu 3piece one) seems fine. The head and block do as well. Is there anything else that I should be looking for? Also I've looked around online (keep in mind I still have dial-up) but couldn't find out which HG should be used, I was running the 2g one. Any help would be appreciated as I would love to actually drive the thing again instead of looking at it.
 
Well I did a compression check before taking the motor all out and it was good across the board. I sent the head off to the machine shop and they recommended leveling all 4 cylinders, putting some tranny fluid in them, have them sit overnight and in the morning see if any of them drained out. Let it sit overnight and all 4 were good so its not the bottom end. Turns out that culprit was the head. It was a remanufactured head and 3 of the guides were bad and all the valve seals were useless. So now they're replacing the 3 guides and valve seals. The head should be done by friday and I'll post an update if that solves the problem. Hope this helps anyone whos having a similar problem.
 
The head solved everything. The smoke was caused by the valves seals being worthless.
