Steve W2 Posted August 12, 2004 Share Posted August 12, 2004 From waht you've described so far it sounds like the turbo whistle every TT makes when spooling. Unless it making a really bad whining sound or the sound has changed for the worse I wouldn't worry about it. Have you ever driven another TT supe before you bought the one you have got?

tbourner Posted August 12, 2004 Author Share Posted August 12, 2004 Yeah the spooling is quite loud, but not really what I'm worried about. It's the high frequency (relatively!!!! 10 times/second ish?) chirping noise it makes, when the boost gauge reads a vacuum below about 20 InHg (generally when I lift off, sometimes in neutral), and usually between about 30 and 40 mph. So far from knowing nothing I've gathered it could be the following: 1. Leak in my inlet manifold somewhere, most likely when I fitted my boost gauge as it appears to have started then. But it is getting louder I'm sure, so it might be coincidence. 2. Turbo going, been told to wiggle my spindle but how the hell do they expect me to do that when I can't even change my own oil!!! If it is getting louder then it points to this, I don't want it blowing up really!! Scoot m8, is it just Saturday cos that's my brothers wedding and I'm not gonna be free AT ALL that day!!

I think the shaft play checking isn't to involved just need to remove some of the intake pipes to expose the end of the turbo shaft and then have a good spin/wiggle......not done this myself though......

tbourner Posted August 12, 2004 Author Share Posted August 12, 2004 Bugger. Needs an oil change as well - endless bloody problems with cars!!! Link to comment Share on other sites More sharing options...
Matt Harwood Posted August 12, 2004 Share Posted August 12, 2004 I could well be going down Southampton way soon if it helps...

dangerous brain Posted August 12, 2004 Share Posted August 12, 2004 Erm no turbo expert as my only turbo is on my diesel and that whistles like a police car lol. But you say it only does it noticeably when you lift off and periodically? Could it be a dodgy BOV? Surely if it was turbine related it would make the noise all the time and the sounds strength if not tone would alter in line with the revs of the engine like my soddin diesel does with highest strength at max revs. Also this boost gauge where was it fitted? How much does the tapping protrude into the line? Ever since I changed my cylinder head gaskets and disturbed the inlet manifold plenum on my omega it has a really weird induction whistle so small incursions in the induction system can make quite noticeable noises. Just somewhere to point a finger. In regards to changing the oil any small garage with a lift will do this job for a few quid if you supply the oil and filter, its certainly no biggy and IMHO the best way to prolong the life of even the most ragged motor.

tbourner Posted August 13, 2004 Author Share Posted August 13, 2004 Yeah I've asked a few places for oil change prices, bout £30-£40 seems the norm. Which oil though is the big question, I've seen so much on this forum about it it's confused me!! Some say Mobil1 some say Valvoline, some say 0-40 is fine, others say you'll need a 50 high temp oil or at least a 10 or 15 low winter value. I'll probably go for good old tried and trusted Mobil1 0w-40 in the end. About the noise, I fitted the boost gauge and it's the cheapest one I could find, so it could very well be that. But if it's the boost gauge pipe or the turbo, then I'd rather its the pipe!!! (a few quid compared to a few grand!!). That doesn't mean I should assume it is and leave it!!! Might take it into dude some time next week for a quick shifty over it anyway. I've had so many 'knowledgeable' people from work telling me what's wrong with it I'd rather get the truth now!

Steve W2 Posted August 13, 2004 Share Posted August 13, 2004 Well Trev if it helps and if your down this way at all I wouldn't mind having a look for ya. Maybe Mr Brain might come too if he's free. Between us I'm sure we could get a reasonable idea of whats going on. That said, the best way would be to get it down to Dude's ASAP if you that worried about it (sooner rather than later!)

IMO you can get overly carried away / worried about what oil is best. Just use a oil around this range and change the oil frequently. The chances of any damage occuring to your engine over say 50K miles by using a halfords special 10-40W compared to a 'top brand' oil is minimal to none.......

Scooter Posted August 13, 2004 Share Posted August 13, 2004 Originally posted by Ian C Dude, how would you know, you sell your supras before the oil needs changing -Ian this is almost true! but i did change the oil every 5K miles on my NA and now do every 5K km (its still counting in KM's) on the 'new' old girl i'm just not too concerned about not using a top brand oil.

dangerous brain Posted August 13, 2004 Share Posted August 13, 2004 Me too, I try and change my oil every 3k miles on all my cars so its just not feasible to stick mobil one in it every time. I used to be in early failure detection on heavy lift helicopters so I know a thing or two about the effects of lubrication and the lack of it. A drain and flush would prolong the life of even the most wirn looking gearbox. Link to comment Share on other sites More sharing options...
Jake Posted August 13, 2004 Share Posted August 13, 2004 Originally posted by Scooter i'm just not too concerned about not using a top brand oil. I don't know if it's true but I've be told that the old oil that gets taken out of your car at a garage gets collected and cleaned in a centrifuge and then resold as budget 'AsdaPrice' type oil. I wouldn't put that in a Supra TT Link to comment Share on other sites More sharing options...

I wouldn't put that in a Supra TT maybe it does, but i don't see anything like that getting sold as new through Halfords. My main point is if you say pickup a 100+ mile UK car with full Toyota service history its only going to have seen a regular 10-30W 10-40W type oil. The dealer is not gonna have a special top notch 'supra' supply unless its been specifically asked for / provided............ Link to comment Share on other sites More sharing options...
dangerous brain Posted August 13, 2004 Share Posted August 13, 2004 Here here I also use whatever reasonably priced fully synthetic oil is available (note I don't say cheapo £2.50 a strained barrel from the pound shop here lol). I usually try and buy it in 25 litre drums to assist in keeping the costs down but my last 2 oil purchases were halfords own grey can fully synthetic buy 1 get one free at about £25. I have now been through 4 cans of that in just over a year and am looking to get some more for my next oil change. Link to comment Share on other sites More sharing options...

tbourner Posted August 17, 2004 Author Share Posted August 17, 2004 Well I went to see Dude and he's now driven my car and confirmed that the turbos are OK! He didn't know what was making the noise though and suggested a few checks, I'll get round to it one day probably, he also said I was getting too worried and he probably wouldn't even notice noises like that. Incidently, also gave me a drive in his car and now I want a single! Link to comment Share on other sites More sharing options...
