what made you take it to the garage in the first place mate, Was it smoking??
yeah it is smoking badly
What just on boost, on overrun, deceleration or acceleration
or all of the above :confused:
only asking cos when i decelerate (as in coming to roundabout) and put my foot down again, i get lots of smoke and the bloodything stinks of oil???
when it sits at idle it smokes a wee bit(white smoke)
when i put my foot on the pedal it just makes behind you disappear

You could, but there's always a chance of it being a duff one, at least with a rebuild you get a limited warranty

You can by a CT26 overhaul kit, i dont think they cost that much. But it may be leaking due to excessive wear in the shaft which has shagged the seals. Check the shaft for play - if theres excess movement then its a rebuild or another turbo
how much are we speaking here

For ???
a. Rebuild
b. New Turbo
c. Seals
Seals come to around 40 bills if i remember correctly, Rebuild (service) kit can cost up to 200 and then you have the fitting of it, and a turbo from fensport starts at 470 ( a recon using the service kit)
is the seals hard to fit
where you get them from

Seals can be got from Toyota as well as the Full service kit, aint had to do a ct26 so know idea on how hard it is..but for a t3 its:-
Disassembly Instructions:
Remove wastegate elbow from turbine housing
Using a boxed wrench loosen all turbine housings bolts--a socket may fit on some
Remove all of the turbine housing bolts except for the two at the top and bottom of the housing. (across from the oil feed-in line and oil outlet) These two screws will hit the center section and be used as "jacking" screws to push the turbine housing off of the center section.
Back both of the above bolts out until they hit the center section. Continue to alternately turn each bolt about 1/4 turn until the center turbine housing is separated form the center section.
NOTE: The turbine housing needs to come off the center section parallel to the turbine wheel. If allowed to come off crooked it will bind on the turbine wheel and possibly damage it. After EACH 1/4" turn try and turn the turbine/compressor wheel. It will bind a little during this part of disassembly. TAKE YOUR TIME ON THIS STEP. If the binding seems excessive turn the bolts back in and try again. More penetrating lubricant may also be needed.
Remove compressor housing by removing the 13mm bolts and metal retainers. Keep an eye out for an 'O' ring around the outer diameter of the compressor seal plate.
Mark the compressor wheel and turbine wheel so they can be lined back up when reassembled. (The turbine wheel and shaft are one single piece)
A socket should fit the turbine wheel "nut". If it does not fit, CAREFULLY secure the wheel by this nut in a vice.
Remove compressor nut then remove compressor wheel.
Remove turbine wheel and shaft from center section-- you may have to tap the end of the shaft to get it out. You should now have the turbo broken down into four pieces:
(a) the compress wheel and nut;
(b) the center section;
(c)the heat shield (also called the dog dish); and
(d) the turbine wheel and shaft.
Next, remove the compressor seal plate by removing the 10mm bolts securing it to the bearing housing. Removing the seal plate will expose the following parts:
(a)the compressor seal;
(b)the thrust collar;
(c) the thrust bearing;
(d)the thrust bearing retainer; and
(e) 'O' ring
NOTE(1): the compressor seal is in the seal plate and has a spring behind it. Use care to prevent the spring form ejecting the seal across the room!!! Also note, the star washer-like thrust bearing retainer is supposed to be FLAT not bowed! Don't be surprised to find yours bowed as this is very common and is caused by thrust loading.
Remove the two turbine shaft journal bearings from the bearing housing by removing the snap rings on each side. The bearings will/should just now fall out from each side of the housing.
Soak the bearing housing in carb cleaner and check to make sure all oil passages are clear.
Remove the old turbine shaft shaft seal and clean off all carbon around the seal area--this is not easy to do! I used a wire brush on a bench grinder to do this. TAKE CARE NOT TO NICK/DAMAGE THE BEARING SURFACES ON THE SHAFT.
Install the new turbine shaft seal using external snap ring pliers to expand the seal--the same way a piston ring is installed. Try to expand the seal only as much as needed to install it. An over expanded ring will make re-installation of the turbine shaft more difficult. As a side note, contrary to what is often believed, this is NOT an oil seal. The purpose of this seal is to keep the exhaust gases from entering the crankcase via the oil return line.
Holly **** Deano! Good luck with this one, you're a braver man than me, I don't think I'd wanna take this on on my own for the first time. :no:
Brilliant instructions Bondango, this should go in the Supra bible section! :)

I've got a twin turbo, and one of the turbos is leaking oil. Is this the seals too, would you say?
I'm trying to order a book from Amazon on turbo stuff, but was hoping someone could give me an idea on what this might be in the meantime, please?
Cheers

Where is it leaking oil from .. is it from one of the inlet pipes? if so its usually a bad seal and that your inlet and ic system needs cleaning out
mr_pink_78
15-09-04, 10:43 PM
Hi there Darket69
I am not 100%, but I would say Yes. I will double-check tomorrow, but from memory that sounds about right.
I assume the cleaning of said inlet and ic systems is a mission?
We should meet up sometime, I'd be interested to compare the mighty Supra TT to another TT. I've had the timing belt changed, so the car's back in use now, which is handy cos I've reversed my civic into a steel girder.

Have u priced a rebuild kit? new seals and bearings. If your exducer and inducer wheels are ok then you could rebuild yourself mate.
Just get a ct26 service kit.
