How far should I tear into it? - aka rover - 01-10-2012
1983 om617 turbo 200K runs good a little bit of a rough idle but started last week at -2 deg without being plugged in, so good compression I would think.
I have the motor out and on a stand and was wondering how far I shoud go into it?
It is a oily mess and i have cleaned it up and was going to replace all oil gaskets and seals.
Should I remove head and replace gasket, or just run it there isnt any signs of leaks.
Should I reseal main pan or just the metal small one?
The IP pump is dry and not leaky but the hand pump sprays back at me when I pump it, so a replace or rebuild is in order.
Turbo is stock but would like to upgrade it and add fuel to the motor to gain a few HP while im at this point. I have a KKK26 I took off my 930 to upgrade it? its the 3ldz from a 79. Not sure it will work or not.
Should I replace timming chain at this point and guides.
Any thoughts would be great
Cheers Ed

Valve adjustment, check timing chain.
Replace easy seals
if you are going to play with the IP, do it on the stand, will be much easier

I have 700,000 miles on the original head gasket in my OM617. If there are no noticable problems with it on a stand. I'd run it. I would do the following if I were to purchase a used OM617 or had it on a stand before install for ease of access especially if in a different chassis.

I'd also do the front main seal and rear if it leaking!

I'd do the front and rear main seals even if they weren't leaking. There a pain in the ass to do with the engine in and there cheap. Do them no forget about them later.
