/ woodsandbarclay In this video I finish the bottom end. Finally!!!! Ialso discuss anaerobic sealant and why it should be used on the upper oil pan.

I am binge watching this series like it was "Cobra Kai"!!
Hahaha! So glad you're enjoying it I made this series because there was nothing like it in existence.
@@woodsandbarclay If this series had advertisements, I would have let them all play thoroughly so you could get paid like all the other TH-camrs. Take care. 👊🏼
Great tip on holding up the piston by using a screwdriver thru the piston pin hole to allow the "old school ring compressor" to fully compress the oil ring! I've had the misfortune of being in a hurry and breaking an oil ring due to it not being fully compressed! If one has the money or rebuilds engines for a living, the custom sized tapered ring compressors are the way to go. For the casual engine rebuilder, the method you have illustrated enables the simple old school ring compressor to works on any piston without the risk of oil ring breakage.
Glad you're enjoying the videos it was a lot of fun making them
Since blow-by gases contain oil vapor... The blow-by gasses from the valve cover on most OM617’s (non California) get plumbed into the air filter (the federal version filter that sits on TOP of the turbo) after passing through the cyclonic oil separator. The gasses go into the intake to get burned, while the remaining separated oil drains back to the pan via that extra port beside the turbo oil return.
Jonesin in for another 617 rebuild update over here...
Great information thank you. I've got another video coming out tonight or tomorrow. It's a pretty good.
They are beefy bottom ends, tractor meets old school race car engine hybrid? Amazing engineering
That's exactly what I thought the internals of this engine look like the bottom end of my race car engine that makes 600 horsepower!
Hello Sr. I am Matias, I come from URUGUAY, I LIKE IT AND IT HAS HELPED ME A LOT. Could you give some advice? I have a mercedes 300sd w126, it runs great. but it happens that it apparently loses oil in the crankshaft seal or seal from the gearbox side. Do you think that you could undertake or make the arrangement without disassembling too much? thanks greetings the car is 1982 om617
To change the rear crank seal you have to remove the engine and disassemble the upper oil pan you cannot fix that in the car.
@@woodsandbarclay thanksssss it helped me a lot!!!!
Интересный ролик 👍👌

I think you forgot to install the timing chain. It's about 19 years since I opened a om617 but if memory serves , you have to install the timing chain in the same time as you install the crank shaft. I might be wrong
My timing chain has a link removed so it can be crimped on at any time
@@woodsandbarclay nice , way easy
What size 12 point socket did you use when torquing the rod nuts down? I can’t find a socket snug enough to get them off.
James this was several years ago sorry I cannot remember. But it is going to be one of your metric sizes. I don't remember if I used a regular socket or a 12-point socket. However if you go to my website you can download the engine manual for the om617 engine and it will tell you the nut size when you look in that section of the manual. That's what I would have to do in order to find out that information.
@@woodsandbarclay ok thank you I will check that out.
Where did you get your manual? I'm looking for one for a 1957 MB 220s.
The om617 manual is actually available for download on my website under the download section. A friend of mine had a PDF copy of it and send it to me a couple of years ago. I just took that PDF to FedEx Kinkos and have them print it into a book. If you need an actual real Mercedes manual eBay is the best place to find them. If you want to download the 617 manual just go check out the download section on my website www.woodsandbarclay.com
Don't the rings turn in their groves as the engine runs and the pistons go up and down?
The science of piston rings is beyond my knowledge. :)
Where did you get that factory service manual? I'd love to get my hands on one.
The one I'm using in the video is actually a PDF that I took to FedEx Kinkos and had them print and put it into a binder. You can download that PDF from my website download section. www.woodsandbarclay.com

@@woodsandbarclay thank you
Nice work
I have massive blow by.
Can I ask where you got the manual?
You can download the manual from my website and then take it to FedEx and have it printed and binded. om617rebuild.com/
jtwoods41978 thank you
@@jeromelee1627 my last comment was supposed to say FedEx Kinko's.. I just gave them a PDF and they printed and binded it for a hundred bucks. I also requested that they put tabs between every section. Anyway the exact PDF I used is on the website
jtwoods41978 thanks again. The manual is something that is a must.
You crank bolts dry, not wet.
I did exactly what the factory assembly manual said to do. This build follow the factory assembly manual step-by-step.
I have my doubts that the engine with the new bearings rotates with such smoothness.
Why?
@@woodsandbarclay Because right now I am doing exactly the same with an old 617 952 turbo diesel ....
And it doesn't turn that easily.
The mechanics of the old guard in my country (Costa Rica) say that an engine of these should not turn easily, when it has new bearings and a plush seal.
Sorry for my bad English, I don't write or speak well
@@gregoryarrieta3675 well that's not true. If you use plenty of assembly lube and everything has the correct tolerances the engine should turn over like it does in this video.
