Ok, I want to thank everyone that helps people like me with the 1001 questions about there MB's, You folks are great! You always have such great advice. Now that I have you all buttered up, here I go with my 1001 questions.

My Goal

A.) My car is a 1990 350SDL, My goal is to replace the 3.5 liter short block (244,000 miles still runs fine) with the heaver/stronger built 3.0 liter short block (187,000 miles). I want to build the 3.0 short block to go another 150,000+ miles.


1) I am buying a "87 TD short block ($600.00) it has 187,000 miles on it, I am going to put in new bearings and seals front and rear. I'm not sure about rings, this will depend on the surface area of the cylinders.

2) On the head I will change the valve steam seals, check the guides and check the run out of the head, I will also use all new head bolts. I will be getting a damaged head with this motor, I am wondering if the pre-chambers are the same as the 3.5 liter.

3) I am wondering if I need to rebuild the turbo? (244,000 Miles on it), Are the motor mount arms the same? Is the fuel pump the same?

As always, on a serious note, Thank You all that take the time to help!
Jim

PS
The "87 3.0 liter motor with 147,000 miles that I talked about earlier didn't work out, So I am going this route.
