stevenhiggster Posted April 11, 2008 Share Posted April 11, 2008 Hi folks My car was running just fine until monday of this week. Now it sounds like my dump valve is just pissing air out and I have no boost? I do have boost but just not nearly what it should have, it still goes fast it just doesn't nail you into your seat like it used to. It sounds a little rough too like the exhaust may be leaking as well as the dump valve, the exhaust noise is a lot louder in the car than it used to be. So all in all it sounds like I'm loosing boost on both sides of the turbo. I haven't got a gauge (yet, one is on it's way) so I cant say for sure what the pressure is, what is it supposed to be anyway, it's a '97 JDM STi version 3? Anyhow does this sound like my turbo is dead or could it be something a little simpler, and hopefully cheaper Please help Link to comment
colin_ross Posted April 11, 2008 Share Posted April 11, 2008 Check the circlip on the actuator, they're famous for it. Link to comment
stevenhiggster Posted April 11, 2008 Author Share Posted April 11, 2008 Check the circlip on the actuator, they're famous for it. Circlip? Actuator? Lets 'pretend' for a minute that I'm a thicko, just where might I find these items and what should I be looking for? Link to comment
jodie typeRA Posted April 11, 2008 Share Posted April 11, 2008 you could be in limp mode i take it youve had a look at the pipe work coming from the boost solanoid yeh... has the check engine light came on (or was it on then went out?) check your ECU for a fault code..the might point you in the right direction (might aswell it only take 2 min)..

There is a rod that runs accross the top of your turbo from the hot side to the cold side. It connects the actuator (round thing) to your wastegate (hindged bar). There is a circlip that secures the rod. If it's come adruft you should be able to see the rod loose at one end. Link to comment

Cheers, I'll go have a look, then I'll check for any fault codes. The check engine light has never come on btw. And I tried re setting the ecu on someone else' advice, it made no difference.

I cant see anything loose, there is a heatshield over the hot side of the turbo so I cant see whats going on under it, but I gave the rod a wiggle and it felt pretty secure to me? Link to comment
superstar_tradesman Posted April 11, 2008 Share Posted April 11, 2008 Check that the vacum hose hasn't come off the dumpvalve Link to comment
euan_r Posted April 11, 2008 Share Posted April 11, 2008 perhaps up pipe or corregatted piece between left and right banks of headers has split, if exhaust sounds louder than before. another possability Link to comment
