I have a blown turbo on my 1992 300D 2.5..... The stamp on the turbo is real small and hard to see...but i know its a Garrett turbo... and something "A0003?" ..

I need to know where to buy a new turbo for my vehicle....

How do you know that you have a "blown turbo?" What symptoms are you seeing?

Click the "Buy Parts" link at the top of this page and ask Phil – he may be able to help you. Even so, a new turbocharger will be very expensive, you may wish to also see if you can find one on a junkyard car. Check the "parts for sale" section of this forum for someone parting out a car similar to yours.

I just had my 1998 E300 turbo rebuilt for $540. And that was with new compressor blade.
Let me know if this is to much. Or I'll post the address and phone number.

I do not know the cost or availability but if (mark the housings first so that you can line them up later) you remove the Exhaust and Compressor housing the middle section with the Bearing housing and Turbine and Compressore wheel (called a Cartridge Assembly) you can exchange it for a rebuilt one.
Sometimes the Bolts on the Exhaust housing are hard to get out. When you assemble the Turbo be sure to use a Never-Seez type compound on the Exhaust Housing Bolts.

Massive amount of smoke coming out of tail pipe, oil inside turbo compressor, and loosing oil.

Well that is an option...but i don't exactly know what size the turbo is....

I'm reading AT0003 on the tag of the 1990 Garrett on my 124.128
(AND when I "Google" that number,Dave's (GSXR's) treatise on replacing
the Vacuum operated wastegate with a Pressure operated one comes up...
Kinda like "Cross Verification")

Below is a reproduction of GSXR's interpretation of the Garret tag:

"For reference, the nameplate data
(which is so small even insects would need to use a magnifying glass to read, sheesh)
is below as well:

465445-2 (this is the Garrett part #)
003-096-98-99 (this is the Mercedes part #)
WC0148F AT0003 (not sure what these indicate, if anything)"

You'll have to shop cartridge prices from Garrett distributors.

[You will have to be very patient with Garrett's distribution system's
"Organizational" operation.'Great products ,Kinda hinky logistics]

I believe in your first post you said there was a tag but you could not read it.
The info you need should be on the tag. Also I would assume Garrett has an application list that they can look up on.

most turbo outlets will be sorta oily,and you could of course be right,but the most common problem i find on the 2.5 is the head gasket will leak near #1 cylinder.
you might want to feel the side play in the turbo compressor wheel (all i see have a slight amount of play).
i have seen the oil less from the headgasket be so bad that liguid oil could be caught in a container sitting at the exhaust pipe.

Well i did feel the compressor wheel and it didn't seem like it had any major play...pretty much very slight. The car does seem like its misfiring and the engine is very noisey with clicking...im not even sure if the turbo was working or not because the engine was so noisey and i couldn't drive the car. The oil pressure gauge also jumps at idle from 1 bar to 2 bar. Possible head gasket then????

i suppose the easiest process i could suggest would be for u to have the engine ideling,open one fuel injection line at a time(i would start with #1)try to determine if when the injector line is leaking fuel pressure off does that cylinder aid in the idle rpm of the engine.
the cyl that doesent aid in the rpm is most likely not developing compression,like a blown head gasket could cause.
hope this helps

Do you have oil in the compressor side or the exhaust side?

Now i have access to any tools i need...can i just do a compression check thru the #1 glow plug hole?

Got that CI, I guess I didn't skim through very effectively.

If the compressor side has lots of oil, check the blowby and oil from the crankcase ventilation first.
