boost leak issues

[918dsm]

so i did a leak test and found multiple leaks not sure if any of them are normal. My tps is leaking also the idle screw and my wastegate, that's all i could hear for now but im sure i will find more. After i fixed a few my car ran and idled great, I took it for a drive then it went right back to idleing crazy, could this be caused by the other leaks?

Sounds like a vaccum leak... make sure your intercooler hose is on the way and tight. One way to check for leaks is spray a can of WD-40 around your engine bay. If the idle goes up, your leak is in that relative location...

Your tps isn't leaking ## throttle shaft seals are

so i guess there is some o rings behind the tps right?? thats what is leaking?

 

[LiquidX]

Yup, that would be a shaft seal

Good way to get your engine dirty and greasy for next time you go working on it, just use a spray bottle filled with soapy water and spray it over all intercooler pipes/gaskets IC and everything else in the intake tract.

What do you mean by saying that your wastegate is "leaking"?

Do you mean your blow off valve instead of your wastegate? Either get a new biss screw + oring or just pull the biss (idle) screw off and if it is in ok shape then put some grease on it or grab an oring from the hardware store.

no i meant the wastegate, i built the boost leak detector and pressured up to 20psi and you could hear it coming out of the wastegate, also behind the tps and the idle screw. Bov was leaking also but i fixed that and 3 leaking vaccum lines everything else seemed to be ok. I bought a new wastegate and it should be here soon, i have been having problems with that gate since i got the car it's external. I also used soapy water to find my leaks
