Condor Posted February 19, 2014 Share Posted February 19, 2014 the last couple days im getting this whistle when i hit boost. its not loud, just on the edge of my hearing and really high pitched. im HOPING its not my turbo but rather....i dont know anything else. could it be a sign of a vacuum leak? any ideas or things to look for/do would be great. its got me wicked paranoid so ive been driving like a granny. haha car is 100% stock.

Industry Posted February 19, 2014 Share Posted February 19, 2014 I Wouldn't drive it another mile until you check the shaft play in the turbo. Link to comment Share on other sites More sharing options...
Condor Posted February 19, 2014 Author Share Posted February 19, 2014 ahhh damn. the more i read in on this issue the more im getting a sneaking suspicion my turbo is on its way out. whats the best way to check for shaft play? popping the DP?

chato Posted February 19, 2014 Share Posted February 19, 2014 yeah pull the downpipe. you might get lucky and have it just be an uppipe exhaust leak which kind of sounds like a tea kettle. But definitely pull the downpipe and check the shaftplay, not worth finding out it was the turbo by having it take your motor. Link to comment Share on other sites More sharing options...
Condor Posted February 19, 2014 Author Share Posted February 19, 2014 ill try to get at it today (wont drive the car until then). also to clarify in my OP, boost is the only time i hear it. just regular driving under 3000rpm it sounds fine.

Condor Posted February 20, 2014 Author Share Posted February 20, 2014 out of curiosity, if my turbo was going, should i have some metal in my oil? or not necessarily? i just changed my oil (about 200miles shy of 3500) to see what everything looked like and it came out fine.

Lafta Posted February 20, 2014 Share Posted February 20, 2014 How many miles are you at, Condor? Just asking, please. Link to comment Share on other sites More sharing options...

Max Capacity Posted February 20, 2014 Share Posted February 20, 2014 If the blades are just beginning hit the housing that is the noise the turbo makes. Mine made that noise a 1000 miles after I got the P0011 and P0021 CEL. It whined during most of that 1000 miles. I got lucky and had no metal in the oil. But the vf40 had lots of shaft play. If you know you have no vacuum leaks, check the shaft play before you start the engine again. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it. Engine Build - Click Here Link to comment Share on other sites More sharing options...
