Turbo rebuild questions
My 84 300D turbo is leaking oil back into the engine. I know where to get the seals (Thanks Rusty). However, i would like to know more e.g.:
Who builds these turbos originally? If I knew that I might be able to get other parts if needed beyond seals. What is the boost these turbos are supposed to be putting out? Where can one get a good/accurate testing tool to test the boost output? Thanks, Dave H... |

besides the o rings and bushing you will need mounting gaskets for the intake side and exhaust side. They are a pill to get apart but very simple once apart. I had my favorite machinist do it and watched. I believe it took about an hour or so.

I have not read of any ready made setup you can buy just for testing. Harbor Freight sells a Boos/Vacuum Gauge. The exterior parts are sold by various internet sellers.

Back in about 2003, someone posted some really good data showing the lie expectancy vs. boost, IIRC. I think something like 10.6 is the right value. Much beyond that and life degrades quick.
My saab has a low inertia turbo with no lag, but only puts out 7psi. Hopefully that one lasts forever!
