Hey guys my 05 mk5 tdi jetta has 230k, turbo use to smoke a little on start up but I didn't care and drove it like that for a while. Then the turbo started making the whistling sound (impeller touching housing) so I knew it was done and it was too much play.
I then replace the turbo with a new china made cartridge keep the rest of the turbo stock. I started the car, after about 1300rpms I think when the turbo start spinning or car has higher oil pressure the new cartridge starts making a whistling noise but this noise wasn't like the impeller touching housing. I drive the car at low rpms for many 4 miles, still whistling. Came home, revved it up to about 4k rpm when the cartridge blow a oil seal and oil everywhere mainly in the exhaust side and the engine started to RUN AWAY (think from too much oil in intake). Had to kill the key to kill the engine.
Then I just bough a BRAND NEW (not rebuilt) OEM Borg Warner turbo and installed it. Car started fine no noise. I was
.
But then again after about 1300rpm the same whistling!!!!!!
I have turned off the car and need to find what the hell is the problem. I can't blow up the brand new turbo. Too much money and too much labor to install.
What could the problem be guys?
Maybe no oil pressure? But i'm thinking that can't be right because when the last turbo blew up the there was about a quart of oil in the exhaust, intercooler and intake piping so there is go to be ton of pressure.
Could it be that I hooked up one of the vacuum hoses wrong? Maybe on tubo actuator/wastegate?
Please any comments or suggestions are much MUCH appreciated.
PS now the band new turbo is leaking oil out of the exhaust side.... OMG!!! Do 05/06 brm engines have a oil restrictors on the oil inlet line? I didn't see one when I told the line off but maybe if fell out???
