HT18 turbo nipple popping out in boost
 

Hey guys,

I have a recent rebuild and have around 1,100 miles on her now. Just starting giving her some mild boost and noticed that last night my car started acting a little bitchy. AFR's would peg out lean and the car wouldn't idle. Under load or throttle they were fine.

Today I found out after I got it home last night that the nipple on the compressor housing of the stock S5 turbo keeps popping out. I haven't done anything new to it since it was run on my last engine. It is tied into my GReddy boost controller solenoid as it always has been. Wondering what I can do to keep it put inside there where it should stay.

It's popped out and come lose like 3 times and doesn't feel snug in the hole anymore. Any input would be great!

Tap it and put a screw in vacuum fitting on it.

the best bet is probably to just thread in a nipple.

mine is loose too, but doesn't fall out, it just turns easily, cant pull it out.

Yeah they all do that... but sounds like mine just got too loose or something. I didn't even think about tapping it. lol. I'm going to do that and look for a 90* bend vacuum nipple after doing so.

Thanks for the input guys!

i used jb weld on mine...
