nutnut Posted March 15, 2010 Share Posted March 15, 2010 Last night i went out to see a mate was driving normal without getting the v on the boost.Then when i left 10 mins later i gave it some wellystopped at a red light on the green light when to floor it again & no boost !Had a look in the engine bay & all pipes are connected, no leaks anywhere.The boost gauge will only hit the 4 psi.No turbo chatter or dump valve noise.My brother in law has have a few turbo cars (evo 2 & 300zx twin turbo)He thinks it could be the actuator stuck.Any other ideasCheers guys Quote Link to post Share on other sites
micky boy Posted March 15, 2010 Share Posted March 15, 2010 Have you checked to see if your turbine blades are ok? it sounds like the blades have gone Quote Link to post Share on other sites
nutnut Posted March 15, 2010 Author Share Posted March 15, 2010 Will be pulling the car apart tomorrow.Hope they are ok Was going to port the mani & wastgate , Decat all at thew same time. Quote Link to post Share on other sites
GAZ@A&G_TUNING Posted March 15, 2010 Share Posted March 15, 2010 coule be the actuator stuck open mate, but i would check and double check all the clamp's on the intercooler piping, also checks there no cut's on the pipe workmakesure the little clip is still on the actuator too mate Quote Link to post Share on other sites
micky boy Posted March 15, 2010 Share Posted March 15, 2010 Yeah take the efi pipe off that go's to the turbo and have a look..... Quote Link to post Share on other sites
harry87 Posted March 15, 2010 Share Posted March 15, 2010 Sounds Like turbos gawn mate. Quote Link to post Share on other sites
ForresGlanza Posted March 15, 2010 Share Posted March 15, 2010 I had this problem too. Turned out that the cir clip on the actuator had come off and so did the actuator. Might be what happened to you too as you said it was fine until you stopped then went to go again. Quote Link to post Share on other sites
nutnut Posted March 15, 2010 Author Share Posted March 15, 2010 I do hope its only a clip.Will let you all know tomorrow.Cheers guys Quote Link to post Share on other sites
GAZ@A&G_TUNING Posted March 15, 2010 Share Posted March 15, 2010 always start with the simple check's then as the chaps said have a look at the blade's etcprop something simple tho, can you here the turbo whinning?? Quote Link to post Share on other sites
nutnut Posted March 15, 2010 Author Share Posted March 15, 2010 no noise at all from the turbo Quote Link to post Share on other sites
ecksjay Posted March 15, 2010 Share Posted March 15, 2010 rofl at people just saying the turbo is gone ^^;most likely a clip or something mate, actuator etc. mine was like that when i first got it, didnt boost at all. was the circlip on the actuator.if the turbo was 'gone' you would have some noise, smoke etc from it. it wouldnt just stop, thats almost impossible based on the design.

nutnut Posted March 15, 2010 Author Share Posted March 15, 2010 Was working fine , Then nothing.No clunking type of noise & no smoke. Quote Link to post Share on other sites
Bildo Posted March 15, 2010 Share Posted March 15, 2010 Why do people insist on giving crap advice? There are numerous reasons that this may be occouring before you suggest something like that.Hopefully it's something simple mate, have you got a FMIC? I have thought my piping was all fine sometimes and it had popped out ever so slightly which was causing a similar scenario. Quote Link to post Share on other sites
micky boy Posted March 15, 2010 Share Posted March 15, 2010 Any advice will help.. thats what we are here for not to start haveing digs at one another about who give's the best advice.My mate's Glanza done the same thing as this guys Glanza and it was the blades on the turbo it was just my opinion to try and help the guy... like i have alot of people on this forum Quote Link to post Share on other sites

micky boy Posted March 15, 2010 Share Posted March 15, 2010 cheers buddy....Hope you get it sorted mate Quote Link to post Share on other sites
nutnut Posted March 16, 2010 Author Share Posted March 16, 2010 Got the turbo off todayBlades are still intact but very hard to turnIs this a sign of bearing problems Quote Link to post Share on other sites
keirz Posted March 16, 2010 Share Posted March 16, 2010 check all your pipe work again, can you hear a leak?if the turbo feels hard to turn it could (key word could) have had some oil starvation. but check everything simple before you resort to sending the turbo off to be checked out.

micky boy Posted March 16, 2010 Share Posted March 16, 2010 Got the turbo off todayBlades are still intact but very hard to turnIs this a sign of bearing problemsYou didnt have to take the turbo off mate to check the Blades....Firstly i was one about the intake compressor wheel not the exhaust turbo turbine.

WallaceGlanza Posted March 16, 2010 Share Posted March 16, 2010 Topic cleaned, if you don't have anything useful to say on this topic then don't bother posting.It is sensible to always check the easy things first, in this case check the actuator is connected, check all intercooler pipes are ok and leak free and that the vaccuum hoses are connected properly etcIf the turbo wheel is hard to turn then it could be seized - the bearing may be damaged, but it's not always best to jump to conclusions. I agree with checking the simple things first. Quote Link to post Share on other sites
nutnut Posted March 16, 2010 Author Share Posted March 16, 2010 Was doing a decat & porting wastegate anyway.Was shitloads of exhaust carbon in there.Gave it a good clean with Gunk Actuator moves quite easyGot the turbo plades to move quite east too.Will get it all back on the car tomorrow & will be checking all the pipe work Hopefully this will of fixed the problem.I drained all the oil from the sump as im doing a oil change while its in bitsnoticed the oil was black & very thickMaybe to thick to reach the turboAs kierz stated (oil starvation).Will let you all know the outcome.

keirz Posted March 16, 2010 Share Posted March 16, 2010 i dont really agree with this thread being cleaned to be honest. i feel that if someone is handing out poor advise then they should be called out for it. but hey moderate as you see fitif there was a lot of carbon build up at the back of the shaft head and around the piston ring area it can cause it to seize up. but the only way to really solve that problem is to strip the turbo fully down and do a full rebuild and balance.ps mickey you can apologise for your ignorance towards me by pm if you feel that way keeps your pride intact Quote Link to post Share on other sites
WallaceGlanza Posted March 16, 2010 Share Posted March 16, 2010 If the oil is very bad that's not a good sign -my original turbo basically welded itself together due to oil starvation becuase of the oil feed being blocked (after a garage did a very bad job changing my cylinder head). Hopefully once you have some fresh oil in yours it will be ok.Let us know how you get on once it's back to together though Quote Link to post Share on other sites

As I already said it's best not to jump to conclusions when looking for a problem but it's good to have a range of opinions/problems to check for when looking for a solution.

ecksjay Posted March 16, 2010 Share Posted March 16, 2010 if it's been left that long that crap oil has starved the turbo, then it doesnt really sound like the engine's been looked after particularly well.might be worth checking everything over, and changing as much as you can, refresh all the fluids etc. Quote Link to post Share on other sites
