i was driving the other day and i popped a coolant line so i replaced it and then filled my radiator with coolant again then the next day i was driving and when i got into boost my turbo/waste gate was making a louder noise... i took a look under the hood to see if any vacuum lines were unhooked and as i presumed i saw nothing out of the ordinary... other problem is sometimes if i rev high like to 6000 to 7000rpms my car sputters out when i let off throttle... the revs go down and once they get to 1000 it drops and dies... it has only done this twice now so not sure of problem... any help on any of these problems would be great help.

 

did the car overheat?

 

it got close to overheating but i stopped before that happened. wat do you think is wrong?

 

Wat kinda noise like air blowing?? any smoke at all??

 

it sounds like air... and i checked it in neutral when i stopped and no coolant or any steam was coming out... so ya and no smoke

 

reach your hand next to the turbo, if you can feel hot air coming out as compared to the rest of the engine (immediate temp difference) you probably are lookin at a gasket leak, aka you blew a gasket on your turbo lol my friend did the same thing in his 240, if this is the problem then your lucky and theyre pretty easy to fix you just have to replace the gasket itself

 

First pressure test for boost leaks. www.boostpro.net/prodtester.html (universal tester) or make your own out of home depot stuff.

 

do i just loose boost if the gasket is blown? or is it harmful to engine? basically i am asking is it still ok to drive with out harming anything?
