my gt3582 spins for about 20 seconds after you shut the car down.

so this fits in with your time frame you are describing.

a manifold gasket cant possibly make noise for more then 2 seconds once the car has been turned off, so you can disregard that as your problem. as its highmounted pull the inlet pipe off and feel the shaft for any movement up or down and in and out.

spin the impellor by hand and listern for any noise.

you could even blast a little compressed air in there to get it spinning to see how loud it is.

but dont get carried away with the air as theres no oil flow in the turbo without the car running.

or with the car runing leave the clamp off the front silicon get someone to turn the car off and then pull the silicon off quickly and see if its coming from the turbine.

Ok, after talking to a friend of mine who is a mechanic dosent look so bad, the loud blowing noise does go away after 1-2 secs and there is another noise for about 20 secs which this friend says could be normal cool down of the engine and i just wouldn't notice it if their wasnt an issue.

cheers for tips on the turbo will rip intake off and check for shaft play ect have a feeling mf have been trying to rip me, everywhere love to say turbos gone without even looking, dogs. so hard to find someone honest who knows turbos in TAS all scaming dogs who are trying rip me.

cheers

      Duncan's V37.......race car?

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.

      Jacks that fit under GTR lips that can reach the subframe?

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.

      BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
