Rob_B Posted November 3, 2003 Share Posted November 3, 2003 Hi All, Drove to work the other night and the car was fine. When I was driving home though the 1st turbo was making a seriously sus noise (not too different from the turbo failure wav on mkiv.com). The sound file on mkiv.com seems to be a one pitch whereas mine changes from a high pitched sound to low depending on how many revs I am doing. Kindof like one of those dodgy swanee flutes with the handle at the bottom that changes the tone. Also there is no boost at all from the first turbo and haven't even tried to see if the second turbo still works. What do you guys reckon. Shall I get my wallet out now or later ? Ta, Rob. PS.. Its also seriously loud ! Link to comment Share on other sites More sharing options...
osso Posted November 3, 2003 Share Posted November 3, 2003 If its seriously loud and you're not getting any boost, im guessing that one of the intake or intercooler pipes have probably come loose.. Link to comment Share on other sites More sharing options...
eyefi Posted November 3, 2003 Share Posted November 3, 2003 Originally posted by Rob_B Hi All, Kindof like one of those dodgy swanee flutes with the handle at the bottom that changes the tone. funny mental image. im with osso on this one, sounds like popped air hose, but it could always be a nice £2000 bill Link to comment Share on other sites More sharing options...
Rob_B Posted November 3, 2003 Author Share Posted November 3, 2003 Well thats what I am hoping for. The main difference between the sound its making and the one from mkiv.com is that mine changes pitch with acceleration whereas the one from mkiv.com is always the same and sounds much harsher. Where abouts is this pipe ? Will it be noticable by just checking round the turbos ? Thanks for the help, Rob. Link to comment Share on other sites More sharing options...
eyefi Posted November 3, 2003 Share Posted November 3, 2003 follow the big pipe that goes from the turbos into the drivers wing and eventually to the throttle body. Link to comment Share on other sites More sharing options...
Dragonball Posted November 3, 2003 Share Posted November 3, 2003 Sounds like a hose - just check every hose and connection you can You should be able to hear any air / boost escape with the bonnet up and engine running Fingers crossed for you Link to comment Share on other sites More sharing options...
Rob_B Posted November 3, 2003 Author Share Posted November 3, 2003 Hopefully good news then.. Cheers lads.. Finding my torch and going out for a check.. Post back in min Ta, Rob. Link to comment Share on other sites More sharing options...
Rob_B Posted November 3, 2003 Author Share Posted November 3, 2003 http://www.mi7.ut.btinternet.co.uk/pipes.jpg Is it pipe number 1 or 2 that maybe suspect ? I have had a quick check of both of them and there is nothing obvious >:/ Ta, Rob. PS.. What the hell is that other bit of pipe over number 2 ? Link to comment Share on other sites More sharing options...
osso Posted November 3, 2003 Share Posted November 3, 2003 its pipe no 2 you should be looking at, at the other side near the battery.. The other bit of pipe over pipe 2 is just a sleave to protect the pipe rubbing on the air intake i think. Link to comment Share on other sites More sharing options...
Rob_B Posted November 3, 2003 Author Share Posted November 3, 2003 http://www.mi7.ut.btinternet.co.uk/pipes2.jpg I take it that this is the pipe then ? I have had a check, but its a bit too dark to see really If I run the engine with the bonnet open, should I be able to hear where its coming from ? Ta, Rob. PS.. Should it really not be driven if I am not sure what it is ? Link to comment Share on other sites More sharing options...
osso Posted November 3, 2003 Share Posted November 3, 2003 Thats the one, check all the hoses going to the charge air cooler, this diagram attached should help you to locate all the connections.. I think No 4 hose is known to be notorious for coming loose, but check them all.. Link to comment Share on other sites More sharing options...
Rob_B Posted November 3, 2003 Author Share Posted November 3, 2003 Thanks for all the help osso.. I'll have a proper check tomorrow in the light and let you know.. Now you mention it though, the top part of hose No. 4 did feel a bit strange. Fingers crossed that thats all it it then.. When a turbo does go, is it likely to go all of a sudden with no warning, or is it usual for them to start acting strange before anything happens ? Ta, Rob. PS.. There is no smoke coming from the exhaust at all when driving. Link to comment Share on other sites More sharing options...
osso Posted November 3, 2003 Share Posted November 3, 2003 No probs, apparently my second turbo has gone on my Supra, and i didnt have any signs of blue smoke out the exhaust, or the death whine, or even sign of oil in the air intake or intercooler pipes... but Paul E's Turbo's went with a bang! and suffocated everybody in a huge black cloud of smoke! some people said it was like smoking a cuban cigar But from what you're describing it sounds like a loose hose..

Marco Posted November 4, 2003 Share Posted November 4, 2003 Heey, just a quick question, is there a difference in the sound when the engine is cold and warm? I have noticed my turbos woosh quite loud when cold (just above 3000 revs, not often I go above this when the engine is cold, but happens sometimes) and when the engine is warmed up its OK again. Now with the cold and wet weather and all, does make some difference... Link to comment Share on other sites More sharing options...
Marco Posted November 4, 2003 Share Posted November 4, 2003 Oh yeah, and check those hoses... Link to comment Share on other sites More sharing options...
Rob_B Posted November 4, 2003 Author Share Posted November 4, 2003 Haven't had a chance to check the hoses yet as I am at work, but with the bonnet open, giving it a rev, it appears the sound is not coming from the hose area, but coming from where the turbos are ( up right from number 1 hose on the top picture above). Is there still a chance that this may be due to a hose failure or not ? Thanks, Rob. Link to comment Share on other sites More sharing options...
osso Posted November 4, 2003 Share Posted November 4, 2003 See Attached I did wonder whether the hose where the red arrow is pointing to looks somewhat twisted as tho its collapsing under the sleave. what i'd do is either take off the hose and check it, very easy to do, 2 minute job, unscrew where the yellow arrows are, or you could get some soapy water and place it where the red lines are and see if it bubbles when the engine is running..

osso Posted November 4, 2003 Share Posted November 4, 2003 It would be a good idea to take off the hose anyway to see if there is any sign of oil, there should not be any oil at all in there!! Link to comment Share on other sites More sharing options...
Rob_B Posted November 4, 2003 Author Share Posted November 4, 2003 I have checked the hose you pointed out osso. No holes or perished parts of it at all, however there is a very light coating of something inside it. It doesn't smell like engine oil though, its more like WD-40 and its a really thin coating as if it has been wiped on rather than pouring through. If I remove the big pipe that goes into the ETCS bit and rev over 2k so the turbo kicks in, I can feel loads of air coming out of it. Does this mean that the turbo itself is still working ? Are there any other things I can check ? Thanks for the help, Rob. Link to comment Share on other sites More sharing options...
Rob_B Posted November 4, 2003 Author Share Posted November 4, 2003 Anyone replaced a No.1 turbo recently ? What kinda damage am I looking at ? Ta, Rob. Link to comment Share on other sites More sharing options...
Dragonball Posted November 4, 2003 Share Posted November 4, 2003 Originally posted by Rob_B Anyone replaced a No.1 turbo recently ? What kinda damage am I looking at ? Ta, Rob. Errr...yep (but thanks for reminding me...sob!) Sorry to say it's a costly one m8...we now do hybrids which are going on my car £1500+vodka Std turbos from toyo are like £2000!! Gulp! There will be some thin deposits of oil within your induction pipes - nothing to worry about Sounds like you need to get yourself down to someone who knows what they are looking for asap!!

Rob_B Posted November 5, 2003 Author Share Posted November 5, 2003 Just taken my car along to a local tuning place. The guy had a look over it and said that they would need the car for a few hours to check over all vacuum hosing and to check the impellers from the turbos, and to check the play they have in them. Then the turbos would need to be sent off to be checked >:/ Their not going to be able to check it in till next week anyway so I am guna spend the weekend hunting down and checking every damn inch of hose work under that bonnet !!! Anyone here that can recommend a garage in the Kent area (I come from Dartford) that would be good to check this out ? Thanks, Rob. Link to comment Share on other sites More sharing options...
Rob_B Posted November 7, 2003 Author Share Posted November 7, 2003 Hi Guys, Just had another check of my car (which is living at work until Thursday when its booked into the garage cuz it sounds way too dodgy to drive) and found oil in the exhaust at the rear. I take it that this must mean that its definately something seriously wrong with the turbo !!! I think bearings or sommat.. boohoo. The garage are going to check all hose work etc, then if the turbo is suspect, send it off for reconditioning / repair. While its in there though I might aswell get something else done to it and am thinking about getting a different exhaust as my current one has a hole somewhere i think. What do you recommend ? Ta, Rob. PS.. I hate turbos. Only joking.. I luv 'em !! Link to comment Share on other sites More sharing options...
