rayhubble Posted February 18, 2010 Share Posted February 18, 2010 sounds like its coming from the primary turbo, only happens at cold idle any ideas before i pull the turbo and do a bearing test? Quote Link to comment Share on other sites More sharing options...
Aaron Posted February 18, 2010 Share Posted February 18, 2010 Smoke the exhaust system through the EBP tube and make sure you don't have a cracked flex-pipe. Quote Link to comment Share on other sites More sharing options...
rlchv70 Posted February 18, 2010 Share Posted February 18, 2010 Could also be exhaust gaskets. Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted February 18, 2010 Share Posted February 18, 2010 1 turbo outlet to down pipe clamp and gasket, and 3 y-pipes for me Quote Link to comment Share on other sites More sharing options...
Mikill Posted February 19, 2010 Share Posted February 19, 2010 Sounds like an exhaust leak like the others are saying. Quote Link to comment Share on other sites More sharing options...
gasgasman Posted February 19, 2010 Share Posted February 19, 2010 Don't waste your time pulling the trans like the book says. Much easier to pull the cab. Which you will have to do anyway when the y-pipe bolts strip off. Quote Link to comment Share on other sites More sharing options...

joshbuys Posted February 22, 2010 Share Posted February 22, 2010 Got one that whistles all the time - hot or cold - just barely touch the throttle with or without a load - left exhaust manifold lower rear bolt - broke off in head. Had one before with same issue - gotta pull manifold to repair properly! Should be fun! Quote Link to comment Share on other sites More sharing options...
