Turbo keeps blowing

Remove the turbo, soak it in diesel, see if turbines start to spin. Normally it's just carbon sticking on the blades or burned out bearing. Let the turbos cool down before shutting off the engine.

The timeing can not be set on it being that it has a timeing belt, It is adjusted when the belt is installed on the engine, There are marks on the engine block

This all depends, if the turbo blows apart or sends parts into the engine, the other thing is it will loose power or go through oil and burn oil causing failure of 02 sensors or converter, i would ask them how bad is it. the turbo could have some end play and still last, most of them dont blow apart but sometimes they do, this is a hard call as i would replace it with the new engine but money can stop me from doing so, if you can afford it then replace it but if not then leave it and keep an eye on it and if it feels like the turbo it not making more power on accel then be careful. good day.

You have a blown turbo.You have to replace the turbo the oil is going into the turbo and being recycled into the engine and being put into the cylinders if you keep driving it the way it is you will eventually blow the engine. It will high RPM and be running on oil it is called a runaway turbo. It will burn every ounce of oil in your engine in a matter of min utes and your engine will seize up before you know it.It is an exspensive part to replace but it is a very easy thing to change even for the most un mechanical person.Make sure you change your oil & filter at the same time because you will probably have diesel fuel in your oil as well.The bearing does not have to be bad in order for the turbo to be bad.

the waste gate is probably controlled by a vaccuum line. i have seen some home grown devices that would adjust the ammount of vaccuum signal the wastegate actuator recieves, there are also some turbo boost controllers that are available in the aftermarket that let you adjust the boost pressure from the driver seat and some even include a "turbo timer" that keeps the car running a predetermined ammount of time after you turn off the ignition so you dont melt down a turbo by just parking the car hot. of course the backyard stuff is cheap and somewhat effective, the turbo boost control unit is a much safer and more precise way of doing it. sounds like you already have some cash invested in this, it would be a shame to lose it over the cost of a boost control unit and melt your engine down by overboosting it and blowing out the head gaskets or the manifold blowing off. this is one i found rather quickly on the internet http://www.turbosmartonline.com/index.php?id=355

Are you priming the new turbo before you install the new turbo?

did you try a blow off if its overboasting with the blow off is it easyer for the turbo to blow the overpressure out and it dont whistle's a suggestion

There is a valve in the top of the Valve cover with a hose that runs to your air filter. PVC valve....... It tends to get clogged. Check/Replace

Most likely the turbo is gone. What ever part of the turbo went, just replace the entire turbo. Not serviceable 99% of the time. The engine will not like being driven for any extended period of time with a bad turbo.

Idle compensation is not correct due to one or more of the following; Bad/clogged air filter, vacuum leak, EGR valve, PCV valve, head gasket leaking, bad gas, water in fuel, fouled plugs, 02 sensors need replaced, locked torque converter, etc. These have not been listed in order of expense; just as they come to mind...accordianman
