Reply-To: 80scool_aus@yahoogroups.com I was climbing a moderate hill at about 65mph today, heard a funny little noise, almost like a hose blew off something, the car lost power and started smoking a lot, boost gauge went to zero. It looks like the turbo bit the dust. I'm going to limp it home on Sunday (I am about 140 miles from home right now), yank off the turbo hose, and check the movement of the turbine. So, Is there anything I should know about swapping in a new turbo? any tricks to this? I've got a guy here in Sacramento California who builds turbos for this engine, he makes either a complete turbo unit complete with wastegate, or just the center cartridge. I'll probably go with the entire unit new. funny thing: twice in the last couple of weeks, I've been sitting in my driveway, idling the engine, ready to take off, and heard a funny noise, like a very sudden and quick "grinding" noise, fairly loud, that lasted less than a half-second. It came and went, that was it. Both times. When the turbo ate it today, it sounded a lot like these two other episodes. the turbo guy said that is not uncommon. At higher miles, the inside of the turbo housing will actually start to disintegrate, and small pieces will slough off and catch the blades. That's probably what I heard. he said the housing on mine is probably completely shot, I will determine that soon enough. Aside from the turbo, what else might I need? Any gaskets? thanks Dana To: <80scool_aus@yahoogroups.com> From: "Ian B" Date: Sat, 31 Jan 2004 14:43:21 +1100 Subject: RE: [80_aus] My turbo blew up!

The biggest issue of concern that I can see is if the compressor blade has self destructed. This will result in pieces of turbo having been ingested by the motor, then spat out the exhaust (hopefully) and then destroying the turbine wheel. :-( If the compressor wheel is dead, you might want to get the top of the pistons, injector tips and combustion chamber checked for damage. A different turbo to the CT26 may have a different bolt pattern to bolt up to the manifold. Let us know how you go.

Turbochargers of these engines, when they go bang, mostly break the TURBINE WHEEL from the shaft leaving the wheel loose in the housing rattling. Worse is that the compressorwheel + shaft can free itsself a little bit when you try to make it home. The trust bearing is still holding it but because the turbinewheel is gone the balancing is gone as well. The remaining compressorwheel and shaft will start to wander a bit an freeing the oilseal constuction so your pressurized Turbocharger will leak and eventually pump oil in the intake section of your engine. Your engine runs on oil but that comes from the tank via a pump you regulate with your throttle. With the engine oil going into the intake you can regulate nothing and your engine go " stampede " killing itsself. I have no other word in English for it ( maybe you guys can learn me ? ) but it means in worst case it can self destruct without you being able to stop it. Specially when we talk automatic gearbox. Maybe best advice I can give is having somebody take the turbocharger of, have it fixed and put it back on before trying to drive it again. In this way you can check wich side is damaged and go from there. In the mean time check your exhaustmanifold because these tend to crack on the topside at cilinder 3 and 4. If your compressorhousing is already full of oil, DO NOT first start the engine but remove the injectors and crank the engine several times to check for oil blowing out the holes. If no oil comes out you are safe, if oil comes out you are partly lucky because you have managed to stop the engine before it ran on its own but you still run the risk of having a, or more, bend connecting rod due to hydraulic lock. If this is the case its mostly 1 or 2 and the engine will run with it but will " waggle " because of unequal compression. When you need assistance with your turbocharger just let me now if I can help you. OZZIE PARTS overhere is the only one in Europe that has cartridges available for Toyota turbochargers or you could switch to a sportunit.

I removed the small 4" hose which connects the turbo output to the crossover tube, and plumbed the crossover tube directly to the air filter. It seems to drive fine this way, no smoke. I didn't find a turbo full of oil, so I think the oil seal is more or less intact. The oil level in the engine hasn't fallen. I'll limp it back home this way, keeping an eye on the oil pressure gauge. I don't think any shrapnel got into the engine, the engine sounds perfect. At least this way there won't be any chance of furrther damage from shrapnel or of a runaway engine. I'll yank the turbo off later this week and have a look at the damage. thanks for your suggestions. Dana
