Bradb Posted March 25, 2002 Share Posted March 25, 2002 Guesstimates welcome. Been away on business today, not spoken to Dealership yet. But it seems they can't sort my Turbo problem. :'( What sort of job is it? Beginer, Intermiediate, advanced? How many hours? How much? Answers on postcards please. Usual address. I must say its been over 10 days now without driving my Supra, I'm getting cold turkey. Need boost.. Quote Link to comment Share on other sites More sharing options...
Ian C Posted March 25, 2002 Share Posted March 25, 2002 It's not the hardest job in the world. A good beginner job, I would say (mine was a head gasket on a MkIII - trial by fire!) First, find your leak, though It may just be a loose connection, not neccesarily a new pipe required. If you are a beginner with the socket set, but willing to have a go (and it's rewarding, in the end ), I would say the following: Make sure you have the right tools for the job - a socket set, spanner set, screwdriver set, and a plier set. Also get some handy stuff like a permanent marker pen, magnetic grabby thing, some disposable cloths, rags to covers the wing and bumper with, that sort of thing. Next - get a big surface area and some cardboard. As you take stuff off, put it, or the nuts/bolts, onto the cardboard and write what the hell it is next to it! The last thing to remember is that all you are basically doing is taking bits off and then putting them back on. It's not rocket science. It's an art form sometimes, and you'll learn patience, rapid healing of fingers, and swearwords, but if you like lego, you can do this Have care, patience, the right attitude and the right tools for the job, and it's not too bad. Go for it, I say. -Ian Quote Link to comment Share on other sites More sharing options...
Bradb Posted March 25, 2002 Author Share Posted March 25, 2002 Cheers Ian.. I'm sub beginner I had trouble changing my oil.. I'll ask the question 2morrow when I speak to the dealership. Its blx. Any pics or url where I can find relevant info pics on replacing a hose? Mr Boostless Quote Link to comment Share on other sites More sharing options...
Guest Martin F Posted March 25, 2002 Share Posted March 25, 2002 Don't forget you will need a trolley jack and some solid axle stands. Watch those chassis rails when you jack up the car, use a spreader plate or a suitable lump of well seasoned wood. Quote Link to comment Share on other sites More sharing options...
matt Posted March 25, 2002 Share Posted March 25, 2002 I can understand a Toyota dealer struggling to diagnose the problem on the Supra.............. but will be amazed that they haven't checked the IC hoses. IMO its more likely to be a vac pipe (still a straightforward and cheap repair, but more of an arse to find) Quote Link to comment Share on other sites More sharing options...

Ian C Posted March 26, 2002 Share Posted March 26, 2002 Well, it could be a vac pipe - let us know the exact behaviour of the car, Brad. E.g., does it boost to 0.7bar, then at 4000rpm drop to 0.3? Or doesn't is boost at all? Or judders at 4000rpm then picks up again? Only boosts to 0.5ish tops, no matter what the revs? That sort of thing. -Ian Quote Link to comment Share on other sites More sharing options...
Bradb Posted March 26, 2002 Author Share Posted March 26, 2002 No boost valve so can't accurately guage. You put ya foot down, it doesn't feel like it boosts very much or at all. Its like driving a 1.4 Sorry I can't be more specific, its been time since I last drove it.. Quote Link to comment Share on other sites More sharing options...
Ian C Posted March 26, 2002 Share Posted March 26, 2002 OK, it's probably boosting, but the boost isn't making it to the manifold. So if it's leaking out somewhere, it's either between the induction Y pipe and the intake manifold, or it's one of the pipes that comes off this. There are two vac hoses and the BOV. Check the BOV by removing it and trying to blow through it. If you can, apparently is shafted. I've never experienced this myself - others may know better than I. Check the vac hoses as well. Do you have stock side intercoolers or an FMIC? -Ian Quote Link to comment Share on other sites More sharing options...
Bradb Posted March 26, 2002 Author Share Posted March 26, 2002 Hiya kids, Ian I wouldn't know if its FMIC or stock. Toyota dealership, have just rang me, they can't fix it! Madness, so I've gotta find someone who can sort it. Gutted. How big a job is it man hours wise? What kinda cost is it likely to incur? Socket set was mentioned.. Whats it needed for? Yours stumped and gutted, (Edited by Bradb at 12:14 pm on Mar. 26, 2002) Quote Link to comment Share on other sites More sharing options...
Ian C Posted March 26, 2002 Share Posted March 26, 2002 Glurk! Do you really not know what a socket set is for?! :shocked: OK - an FMIC is a Front-Mounted InterCooler. If you have a clucking great radiator-like thing in the bumper hole below the numberplate, you have one. If you have a tiny radiator like thing in the small numper hole below a headlight, you have a stock intercooler. The reason I ask is because it changes the path of the induction tubing a bit. If you need to remove stuff like the headlight or the airbox in order to check part of the induction tubing for leaks, you'll need a socket set. It's handy for putting those bits back as well A Toyota dealership, in my opinion, should be able to fix *anything* on any Toyota ever. I find it hard to believe how poor this lot are - what is the name of the dealership, for future reference!! how big a job - the worst that could happen is that you need to take apart the whole induction system from the turbo outlet to the manifold to find the leak. It's just taking bits off and putting them back on again afterwards, don't worry. Personally I would allow a couple of evenings solid on it if it came to that. There are probably guys on this list who could sort it in two hours flat with their eyes shut If you are a novice, give yourself a week and take it steady. Costs - find the most expensive pipe that could be ruptured, and budget for replacing one of those. Then double it, just in case Worst case scenario if it's not wrecked turbos? A huge hole in an intercooler. I don't know how much those cost, but it's be a few hundred -Ian Quote Link to comment Share on other sites More sharing options...
FaithStalker Posted March 26, 2002 Share Posted March 26, 2002 Bradb, Did you get it from JIC? JIC use a garage right next to them, I've been there a few times, they are pretty good in terms of "look around, raise the car etc" and know quite a few things on supras (they service them/repair etc) . they dont charge the earth and you probably could just drive along and tell them what is happening. They will take it out for a test drive (they did with mine to discover the TRAC fault), and they seemed to be more than willing to help. Phone JIC and get the garage number from them - i cannot remember the name or the number. Being south london might not be too far away for you? I'd recommend getting a boost gauge, a really cheap one off the net, take along with you and get them to fit it (even if its just dangling in the footwell) at least you can see whats happening. I think torqueic or whiffbitz will have some cheap. you could spend 100 quid on someone looking at it for a few hours, when a boost gauge might point you at it there and then !

Bradb Posted March 26, 2002 Author Share Posted March 26, 2002 Cheers Ian. Superb. I know what a socket set is for, of course. But I meant in terms of this job. I've a friend who owns garage complete with hydralic ramps, is it an under car job, or through the bonnet? I'm just after any further advice/pointers that will help him have a look as I'll print out this thread. Thanks Ian/guys. Quote Link to comment Share on other sites More sharing options...
Ian C Posted March 26, 2002 Share Posted March 26, 2002 Primary access via the engine bay. I think that if you need to check the intercoolers, you will need to jack the side of the car up and remove the front wheel and the wheel well lining to get at them (I may be wrong, I've never attempted to access a stock IC, but this seems the most logical way) Going under the car may help if it's an FMIC, and for checking the intercooler to intake manifold piping. An undertray will have to come off for this, I suspect. Easy enough on a ramp Sorry about the socket set misunderstanding! -Ian Quote Link to comment Share on other sites More sharing options...
Lee Burley Posted March 26, 2002 Share Posted March 26, 2002 Without a boost guage on the car you are really going to be guessing where to start, but the cheap and easy way to do it is to roll up your sleeves and start feeling all the piping, hoses and clamps from the injector intakes down to the intercooler. Be quite rough with them and pull them about a bit, because if they are loose then they will blow off at some time in the future so you may as well fix them now. The plastic tubes which run across the bottom of the car just above the plastic sump cover were a favorite place for a leak, as was the top connector to the intercooler at the left hand side. When I fitted my FMIC, all the piping was replaced except the top pipe onto the turbos.... at least I now only have one place to look when a pipe comes off! You dont need any special skill to fault find the piping, just patience, arms like a gibbon, and lots of germoline for your skinned knuckles. Oh, and dont be tempted to try it with the car hot (or running)! Quote Link to comment Share on other sites More sharing options...
Bradb Posted March 26, 2002 Author Share Posted March 26, 2002 You lads are superb. Really. Is there any other references that will help my guy who knows his way around cars find what he's looking for? Thanks so very much. Armed with that, it'll be a CTRL-P moment.

Ian C Posted March 26, 2002 Share Posted March 26, 2002 One last thing - if you are going to print this out and give it to a bloke at a garage - BRAD WEARS WOMENS UNDERWEAR!! Sorry :biggrin: Couldn't resist! -Ian Quote Link to comment Share on other sites More sharing options...
Bradb Posted March 26, 2002 Author Share Posted March 26, 2002 Love it.. Good call ian. just had a look at all those big pipe things nad they were loose.. Tightend em up.. still not boosting properly. Need to get replacement hoses.. Part numbers please kids.. of the 3 big hoses. Ta. Back online Thursday evening.

Ian C Posted March 26, 2002 Share Posted March 26, 2002 Actually, what you need to do is remove the hoses and examine them... Yes, it's hands-dirty time! You will be gutted if it's a dodgy little vacuum hose coming off the Y-pipe and you've bought new intercooler pipes! I'm trying to think of a sure-fire way to diagnose where the leak is without too much surgery - does anyone else have any ideas? -Ian Quote Link to comment Share on other sites More sharing options...
Guest Mycroft Posted March 26, 2002 Share Posted March 26, 2002 Detach the piping as close to the turbos as poss. and as far up the other end as poss. (near the injectors) take your vacuum cleaner outside and attach 'blow' end to the hose nearest the turbos and SEAL the other end, get some strips of cloth about 2" wide and soak them in a solution of fairy liquid and water and wrap them around the joints, secure them fairly tight., switch on the vacuum cleaner and watch for bubbles! So even if you have a fault your neighbours children will think you are amazing and your car is really cool! It is a bit of a palaver as a party trick, but hey!

Guest Martin F Posted March 26, 2002 Share Posted March 26, 2002 The Americans use an old soup can stuffed in the piping and a tyre valve attached. They then attach a compressor to the valve and pressurise the intake system. I guess Brad doesn't have a compressor, but if he takes it into a garage it's a method they could use. Just sitting here typing this, i wonder whether Bradster has had a stone go through the SMIC. Quote Link to comment Share on other sites More sharing options...

Ssshhh - that was my worst case scenario a few posts back - don't bring on ill omens.... I was thinking of some way of using liquid to test the leaks, but I figured filling your induction system with water wouldn't be smart The 'bubble wrap' idea mostly avoids getting liquid in the induction tubing, but a) it wouldn't check the intercooler, and b) you would have to take all the pipes out to wrap them anyway, which defeats the idea of a way to test without major surgery By the time they were out, I would have thought you could tell where the leak was! It's enough to lose all boost, remember, so I'm assuming it's a large one... And who has a vacuum cleaner that blows instead of sucks? :biggrin: What about a can of tyre weld? (joke) -Ian Quote Link to comment Share on other sites More sharing options...
Guest Mycroft Posted March 26, 2002 Share Posted March 26, 2002 You need only disconnect the two ends wrap the joints and wait. Ian C, I know you are not technical but really...all 'vacuums' create suction by forcing air out the 'other' end, you are a funny man!

Lee Burley Posted March 27, 2002 Share Posted March 27, 2002 If you have got a stone through the SMIC then dont panic, there are quite a few stock intercoolers lying around, like the one in my loft. Come to think of it I will have a whole set of piping to go with it apart from the connection onto the turbos. Quote Link to comment Share on other sites More sharing options...
Bradb Posted March 27, 2002 Author Share Posted March 27, 2002 Struggling to get someone in my vicinity that can isolate and sort this problem. Does anyone know of anyone who could have a look Saturday morning and if its a hose related problem help buy and replace in the afternoon? Ideally this Saturday? I'll travel and of course pay.
