Advice on replacing TDI300 Turbo

Hi All

I plan to replace the turbo on the 300tdi this weekend.

Question, do i need to use any kind of sealant when I fit the new turbo into the manifold or would the heat simply cause both parts to fuse together snugly?

Regards
Ed

Hi Ed, I had mine on the 200 tdi rebuilt and if it anything like it I would suggest before changing them, try to have studs and all metal self locking bolts for it as well as new metal compression gasket. You will most likely need heat and penetrating oil to have the bolts come out. Otherwise it is pretty straight forward.

Good luck !

Pat

Thanks Pat!

I got new bolts (the blacks ones). I have a new pair of the C clamps.

I plan to take it to the machine shop to extract the old turbo out of the manifold.

Is it the gasket between the manifold and cylinder head?

Its the one between the turbo and the engine exhaust manifold and between the turbo and its exhaust manifold. But this was on the 200 tdi, it might be different from the 300 tdi.

Just checked the 300tdi shop manual which says that you'll need new manifold and exhaust flange gaskets and a new clip to connect the control lever to the wastegate spindle.

I've never done this but I have the manual... (yipee for me)

Be very careful you don't have the oil return line kinked or compressed after you put in the new turbo. I used to rebuild turbos and saw a lot of failures due simply to the fact that the return line was restricted.
While you're at it, I'd relocate your oil pressure sending unit to the turbo. Longer life comes from making sure your oil pressure is good at the turbo before driving.
