Deer Killer Posted May 4, 2006 Share Posted May 4, 2006 I suspect it's the donut gasket, but everytime I get under the car and feel around it, the leak mysteriously dissappears. Usually this means that when driving in close quarters to walls/other cars my car sounds like poop. Sometimes. I've had all the heatshields off the manifold and everything seems perfectly tight up there. Any idea as what to do next? Anyone else have trouble with the donut gasket? (I've noticed that the Cobb DP seemed to be slightly short, and the spring loaded clips really had to pull together the parts vs just keeping them snug. I hope that's not an issue, because that would suck.) Link to comment Share on other sites More sharing options...
BoxerGT2.5 Posted May 4, 2006 Share Posted May 4, 2006 Check all the nuts, make sure they are tight, DP/UP/MP/Manifold. Check if there is any soot around any of the flanges. What exhaust mods? DP and what else? OBAMA......One Big Ass Mistake America! Link to comment Share on other sites More sharing options...

What exhaust mods? DP and what else? DP and gutted UP with a plug for the EGT. Can't find any soot.. I doubt it's from before the turbo. No problems making boost and no strange noises under boost. Still I took off all the heatshields, and even sprayed everything down with soapy water.. Nothing. Link to comment Share on other sites More sharing options...

Deer Killer Posted May 4, 2006 Author Share Posted May 4, 2006 Why do you think you have a leak? Loud whistle? Sometimes it sounds like a rickety old car with a rusted out exhaust. NA sound. Especially when cold. i.e. as you are pulling out of a parking lot with the windows down. Link to comment Share on other sites More sharing options...
TSiWRX Posted May 5, 2006 Share Posted May 5, 2006 DK - strange.... What I've learned recently is that even with a relatively large (i.e. a missing manifold-to-up nut) pre-turbo leak, you can still reach target-boost. I would guess that you've got a blown gasket somewhere, too, but why the heck it's not showing up with soapy water or by feel, I truly don't understand. Have you tried having someone rev the vehicle while you look for the leak? <-- I love Winky, my "periwinkle" (ABP) LGT! - Allen / Usual Suspect "DumboRAT" / One of the Three Stooges '16 Outback, '16 WRX, 7th Subaru Family Link to comment Share on other sites More sharing options...
LIZARD Posted May 5, 2006 Share Posted May 5, 2006 Just a thought but have you looked for the leak while the car is cold? It seems like this is when you notice it most and maybe with heat expansion it is not quite as evident.(?) nick.
