I found 2 boost leaks. The IC pipe was leaking from the hole where the alcohol nozzle is mounted. Easily fixed. But the other leak is a little more of a PITA.

Its coming from a plastic piece under the intake mainfold where the 2 hoses from the TB go. The red lines show where the 2 plastic barbs broke off and also the flow of the leaking air. My guess is it snapped when they swaped in the new block, but who knows. Anyone know what this piece is and where I can get another one?

The piece looks like its attached to a sensor thats not plugged in. I assume its not necessary since i'm using an EMS with MAP conversion. So my other question is, if the sensor isn't being used, can I just use a plastic "T" to connect the 3 hoses and bypass the sensor?

 

bump

 

hard to tell from that pic but it looks like its just a combi valve or some kind of solenoid. what its purpose is I couldn't tell you. I'm sure you can get one at the dealer though.

 

Thats a 3 port solenoid for the EGR system. Not the EGR valve itself, just the solenoid that operates it.

Dont really know if stand alone uses it

 

Its been unplugged since the EMS install, so i'm thinking it doesn't. I'm going to connect the hoses with a plastic "T" to bypass the solenoid all together.
