Oh boy where do I start... Well just replaced the head gasket because it was suspected to be leaking, no water in oil just at high boost/rpm the engine would bog up and I would get smoke out the exhaust too at idle. Well the engine does not load up at high rpm anymore but umm I just saw it smoke at idle like alot of smoke then I reved it up and then a mintue or so later it was running clean again... Before and after im still having idle problems if u rev it and let off it will die. The idle control clicks like its suppose to also. What could cause this smoke? Could it have somethin to do with the idle too? The smoke scares me, it was a stock HG torq to 85 lbs with ARP studs, a mechanic helped me with it and said it woudent leak but idk.. The turbo is new so I dont think its the turbo oil seals. I use to own a 2003 Lightning and it would smoke on start up and it was somethin like the valve seals? My old motor use to smoke a good deal now and then at idle but it had a metal HG and I dont think it was ever leaking so maybe its somethin elce
