617.952-220k-Getting built up
larsalan I guess I need to look at this stupid ass drip shit. What you have to like mess with those elements on the pump? What a fucking hassle. then use some wire to hold the throttle open or some shit?

interesting...does it stand engine temp nicely?

I've never owned a clean enough engine to use them, but waxoyl is supposed to be one of the super-duperest coatings:

If the aluminum parts are already painted then you're set, but if they're bare aluminum it won't take long for them to get crusty.

On the more porous aluminum Like the intake and accessory brackets I bead blast them and us a clear coating from POR-15 it works great. On the smooth aluminum pieces like the oil pan and valve cover I soda blast them to get the crud off but doesn't etch the surface. Spray them down with WD-40 once in a while as it soaks into the pores, and pressure wash the engine off once in a while to keep it clean at the car wash.
(12-23-2013, 11:25 AM)OM616 May I ask where you got your pistons from and how much they where? I'm trying to source parts for a 616 turbo build and new 617a pistons and rods are hard to find.
I reuse the pistons as long as they have no scoring and measure out okay. I have new sleeves put in the block and have them bored to the STD. pistons. The rods I have rebushed and resized and balanced.

If it's not too nosy of me, about how much did it cost to rebuild the thing
?

I buy all my parts from Autohaus in Arizona. They have high quality German parts and are the most reasonable I have found.
I have about $3800.00 in parts and machine work not including my labor to assemble it. This includes all the machine work and balancing, and having the injection pump resealed and recalibrated.
(12-23-2013, 08:39 PM)MFSuper90 Very nice looking rebuild. I bet balancing the rods will make a noticeable difference.
The balancing was $150.00 well spent. I was supprised how far off the crank, pistons, rods and flywheel were off from the factory. Balancing should make a major difference in performance.

As much as I know the balancing in the Mercedes factory was done by part matching, so you could have a "light" piston and a "heavy" rod and both together would be within specification.
When everything was completely assembled the engine block was dynamically balanced on a bench before they did put the cylinderhead on.
Of course the standard balancing from the factory is not the best there ever is.
Did you use a thicker (metall) head gasket for less compression or do you want to keep the engine more in a "standard" range?
Anyway, very nice rebuild!

(12-23-2013, 11:25 AM)OM616 May I ask where you got your pistons from and how much they where? I'm trying to source parts for a 616 turbo build and new 617a pistons and rods are hard to find.
2 yrs ago when I did my rebuilt ... before measuring the pistons
I asked stealership,...thay were available overhere and price was
somewhat around 3200 USD iirc.
luckily my pistons measured ok and I went with overhaul
described by zeeman...new sleeves...etc...
500SEC euro gen II powered by OM617a stolen from 84 300SD .... with 280se transmission now

12-25-2013, 02:47 PM #13I've always rubbed bare aluminium with a rug drenched with weapon oil. Works well and doesn't give colorizsations like waxes usually do. The little dust it collects can be wiped off easily with another oily rug

I'm swapping into an FJ43 Toyota Land Cruiser and have a neutral flywheel at the moment.

01-10-2014, 06:29 PM #15Can you tell me how you balanced your engine? Mine is at the machine shop right now and he is an amazing race engine builder (mainly V8's) but he is having a hard time figuring out how to balance the inline 5 cylinder. I've checked to see if there is any difference between the 5 and other inline 5 cylinders and I can not find a direct reference for Mercedes. The only reference I can find for another inline 5 is for the Audi's and they also use a 50/100% rotating to rotational weight for using bob weights.

They had to use the OM617 5 cyl. crankshaft, and hung the bob weights on it. They weighted the pistons, rings ect. to get the right bob weight. They also matched balanced the OM617 flywheel from each engine to the Jeep and Toyota flywheel on the conversions I am doing. PM me if you need to contact the shop that did mine.
