lms1977 Posted April 3, 2012 Report Share Posted April 3, 2012 Ok so I run wide open up a hill the have to stop on hill I hear a hissing sound like a air leak from a air hose. it only does it for 2 sec then stops ? I checked the over flow and rad it is not using any water and is not hot at all. if my crank seal on the right side went in therory it could pressurize the engine and come out somewhere I have no oil in the hose from the vent thou I am going to pull all the lines off to see it there clogged etc and I want to pull the side cover off anyway to put a billet basket in it still the stock one anyway I'm wondering if anyone can chime in here and give me some other things to look for. sunday was the first time it ever did it toward the end of day ??? hope I did not destroy it? thanks Mike Quote Link to comment Share on other sites More sharing options...

Zwiser Posted April 3, 2012 Report Share Posted April 3, 2012 Did you do a leak down test on the engine? Was the engine hot? maybe it was some steam rushing down out the overflow. Quote Link to comment Share on other sites More sharing options...

BigRed350x Posted April 4, 2012 Report Share Posted April 4, 2012 Check your coolant level in the radiator. Just because you're coolant bottle doesn't have any fluid in it doesn't mean you can't be low. Toss the stupid coolant bottle in the trash when you are done, they don't do jack shit....

Toss the stupid coolant bottle in the trash when you are done, they don't do jack shit.... as I stated in 1st post I did check the radiator just to make sure it was full and the engine really was not hot enough to puke coolant Quote Link to comment Share on other sites More sharing options...
