So, after searching and reading several threads concerning the expected life of a stock TD04 and the symptoms of a failing turbo I'm beginning to draw the conclusion that I may be due for a replacement or upgrade.
First, some history and a rundown on my car and the symptoms it is displaying. I have an '06 fxt with 166k miles, the only mods are a stromung cat back and a Cobb stage 1 ecu reflash. About two years ago I experienced what seemed to be a boost leak, my turbo would spool well initially for a second or two then there would be a noticeable drop in boost and acceleration. No real whistling noise like it was hemorrhaging boost and unfortunately I don't have a boost gauge but it was definitely down on power. Also no CEL, no smoke, no untoward noises and car would rev to high rpm with no issue, just took longer to get there. I pulled the intercooler and inspecting all duct work for leaks to no avail, I then reinstalled the intercooler, duct work and tightened all clamps. This did not fix the issue. It did however miraculously disappear a few days later and ran like a champ up until a couple days ago when...you guessed it...the same symptoms have reared their ugly head once again.
My question is aside from a boost leak, what is a probable cause for this issue? Malfunctioning/worn BOV, EBCS or is my turbo getting tired? I know 166k miles is a boatload of miles for a stock turbo and TD04'S are cheap but before I start throwing parts at it I wanted to get some opinions from the fine folks on this forum. Thanks in advance.
