Re: LS7 engine problem

Iain, interested in the cooling system , this could be a factor,

Prior to any problems with the car. I used the car for nearly 2 hours giving the car full use on the race track, driving it at its maxumin power. coming in only to change passangers, however i did slow the car down for a lap prior to comming in to the pits. turned the engine off changed passanger & off again. this is the hardest i had driven the car. When I had finished I put the car on the trailer & drove home.

Only on start up after leaving the car over the weekend I noticed the problem of the steaming exaust. It seemed to go away & did not steam again untill i took it out on track again. used it for around 20min steamed at first then went away although I thought something was wrong Oil & temp read okay with 90degrees on the water & 100lb on the oil. ocaisionaly temp creeps up after full power on the track to just over 90.

Another point when I drained the radiator down water did not flow out only trickeled out & did not drain the engine? so air lock? or hot spot?.

I hope this helps in the thinking.

Thanks
