Need advice maybe bad turbo seal?

[sean44kyle55]

so i did a boost leak test im my 95 tsi awd stock everything except a boost gauge. so i put 15 psi in it and first off i heard like a bubling noise sounded like it was coming from maybe the oil pain or radiator im not sure but when i did it i found a lil vaccum leak it was the egr solenoid but the weird thing is that on my boost gauge it barley moved when i pressserized it and it idles like cramp right now partly because bad front o2 but vaccum sits at about 10 hg when i was told it should be about 20 so any advive would be helpful cause right now my old dsm that was a fwd esi would beat my tsi need some help

First off, work on your spelling and grammar as you need some serious help on that. As for the boost leak testing, start at the throttle body find/fix the leaks then move to the IC and then the turbo inlet. Use soapy water and look for bubbles. You should hold pressure for about a min or so depending on how well your internals seal.

It's not unusual to hear slow bubbling during a BLT. Some air leaks past the compressor seal and bubbles from the turbo oil return tube which is submerged in oil at your oil pan.

You need to fix all the boost leaks. If it doesn't show up on your boost gauge, you've got a bad leak.

And fix your front O2 sensor. It's pretty easy.

Fix what you know is bad and see what happens.
