I was putting on a new exhaust gasket set today and when i was tightening down my oil supply for the turbo the cast broke into three chunks... Does anyone know what this part number would be or where i can find one... its off of a 1981 300sd

Thread on this about six months ago. I think the consensus was to head for a junkyard. My recollection is the dealer price is high.

ok will do... just sucks my turbo looked brand new inside

I believe the cast piece is welded onto the pipe. X2, get one from the JY.

Even though a W116, W123 and W126 use the OM617 engine, the oil feed pipes are a little different with the bends, and how they attach on the rear of the oil filter housing.
The 123 has an oil pressure line going to the oil gauge, and the 126 is electric. so the plate on the rear of the filter housing is a little different. Not sure with the W116.

when you replace the feed pipe, be sure to attach it at the R/R corner of the head. there is a bracket that bolt to one of the 2 bolts that connect the lifting bracket to the head. the bracket is about 3" long and the clamp on the feed pipe bolts to it.

If you forget, the vibration from the engine will crack the feed pipe. In my cast, right where it is welded to the lower end where it bolts to the oil filter housing. It is high pressure, and will pump out the oil pretty quick.

We are advised to NOT judge ALL Muslims by the actions of a few lunatics, but we are encouraged to judge ALL gun owners by the actions of a few lunatics. Funny how that works

i found a used turbo off a 83 300d... would this be exact match

Now Iam confused, what broke exactly? I was under the impression that it was the oil line, so now it is the turbo housing that broke?

Splaine to us.

Yeah the turbos from eithe car will work, same engine.

i added a picture... the part that broke is the actual turbo housing... the threading that holds the line in place busted apart with little force being used... the lower thread hole on the turbo itself...

Bummer.

Quickest fix is replacing the Turbo. Doubt that piece can be repaired and safely trust it to hold.

If where the Bolts thread into the Turbo Housing broke the only possible fix I can think of would be to thread the Oil Inlet Hole for a Brass Fitting.
Does it seam like the Bolts were too short (this is something that could cause the cracking you describe); only had a few threads screwing into the Housing?

Is there substantial threads left in the Housing? If so it might be possible to replace the Blots with Studs.
The Studs could be epoxied in with JB Weld Brazed to the Housing (could result in burned Oil flakes in the Oil inlet).

That would mean changing the Oil inlet line over to a Flexible line.
They sell Banjo Fittings that Have pipe threads on one end of them.

Another detraction to the threading issue is keeping chips out of the Oil Inlet Hole and making sure the Fitting has a large enough passage in it so it does not cut off the Oil Flow.

Greasing the Grooves/Flutes on a Tap works out well if before the Tap gets full of chips you pull it out; clear the Flutes of Chips and re-grease it.
To a certain extent filling Drill Bit and Tap Grooves can trap the Chips. However, this is not as sure on the Drill Bit because unless the Drill Bit it turned slowly the the Grease can get hot and runny and not trap the Chips.

Can't see from the pics well where the 3 chunks of cast metal broke. I see that the gasket broke, but not the cast metal. If it's just the gasket, just replace with new.

It is the Threaded Hole on the right of the Photo, I had to copy his Photo and blow it up to see it; still not entirely clear.

When I had my Manifold and Turbo of I reused the Manifold and Turbocharger Gasket by coating it with a thick coat of Copper Coat.

Even Though in the case of the Exhast Ports and the Turbocharger Flange the Glue part of the Gasket Sealer will burn off; Copper Coat (Kote?) has Copper Metal Particles suspended in it that are going to smash and help form a Seal.

However, take some time shaking the Can up to get the Copper Particles off of the bottom.

Otherwise the Gasket is supposed to be replaced after each use. TO3 Type Turbos are used on a lot of Cars. Speed Shops sell the Turbo Mount Gaskets and could likely match one up for you.
Besides the stamped Metal Gaskets there used to be a laminated type, Metal with some softer material in between (in the old days the material was asbestos).

it was the bottom hole.. that whole light grey area where the gasket broke away... the metal cast also broke away.. i lost about 1/4 inch of metal threading.... i was soo pissed when it cracked cause i was just about finished with my gasket job....
