I picked up one of these cars recently. Pretty niche shape. Your channel is already saving me tons of headache. Even same year as mine. Perfect videos for fixing up the little things wrong with her. Ain't going for a restoration or anything, but it'll be nice for everything to actually work correctly eventually.
about to pick up a 1981 300sd this weekend, this is the first maintenance job to be done. thank you content. btw, its going to be running on JET-A fuel.
You mean I don’t have to buy the angled 14mm wrench for $100? Lol . And I know I can’t be the only one screaming “Paint the cover!” “Paint the cover!” Very nice video man. Very helpful.
Thanks ! I'm sure the official tools would be much easier to use. No denying that. For a beginner wrench turner that would be the correct way to go. However I was able to knock out this ugly wrench in about 10 minutes using a cheaper Harbor Freight tool.
I saw 15 views but no likes or dislikes when I saw this. Watching you do this is much more fun than watching paint dry. Lol I always took mine in and let a mechanic do the adjustments. Now that I know how to do it I don't have a car to practice on. Oh well. I assume you need a completely cold engine and the clearances are to allow for expansion when the engine gets hot. I have heard the clips that hold that cam oiler tube are a problem on some engines. If I remember right they used plastic clips on some and they would break and the tube would come off. Disaster waiting to happen. They're not plastic on yours are they? What's next? Still 15 views, 2 other comments when I fired mine off and mine is the only like. What's up with that people?
If you have not done this before my advice would be to use two wrenches if you are not already. (Preferably flare nut style wrenches) Do not try it with a regular open-end wrench. Remember that to loosen the setup, turn the top nut counter clockwise while simultaneously turning the bottom nut clockwise. Using two wrenches is preferred to break things free. Once they are free, the adjustment is straight forward.
@@ImpalamansGarageI’ve done it! Had the wrong idea of which direction everything was going in. Thanks for replying by the way. Job is done and she runs great 👍
great video!! Ohhh those plastic vacuum lines... haaa... mine are getting shorter and shorter ;) What does the service manual say on when a valve adjustment should be done?
I edited the description with a link to the FSM site where you can download the valve adjustment procedure. The procedure does not indicate the interval but everything I've read on line indicates that it should be done every 12,000 miles.
After I clipped the end off of the vac line I put a rubber tip on it like the ones that go on the vacuum switch over on the in the driver's side firewall. I had extra. Worked well.
Hi I just bought a 300SD and the engine has seen better days so I was thinking about rebuilding it and was thinking of turning it into more of a performance car. I was curious how much horsepower could I max out while keeping it reliable and safe. With all performance parts going into the engine what would be a reasonable amount of power? I am trying to get around 300-400 hp out of the engine and wanted to know if that was possible?
Honestly I'd shoot for 200. If you were able to obtain 300 to 400 hp from an OM617, you'd blow out the transmission and differential when you put your foot into it. The first place I would start with regards to thinking about serious power for these engines is www.doomsdaydiesel.net/. He knows a lot more about hopping up these motors than I ever will.

Glad to hear things are working out! Some items can be pretty challenging for sure but the end result is a classic you can drive every single day.

Thanks definitely most clear video on youtube for this job, much appreciated
Good info! I like how you project the manual on the screen. Very fancy!
Thanks. Going to be doing this once it warms up

I didn't see any plastic under that valve cover, but then again everything was covered in oil. :)
@@ImpalamansGarage This car is old enough I imagine if they were plastic they would have broken up by now so they are metal.
Great job man thank you
You are the man! Nice work. Thanks
I want to know are you familiar with the Mercedes-Benz? OM355 and will this procedure work for that engine to
I'm not familiar with the OM355 so I cannot advise you.
If the locking nut won’t budge do I force it?

Nice video,very informative. I didn't hear what the gap size is for the valves. Maybe I missed it.👍👍
Cold Engine: Intake - .10mm, Exhaust - .35mm
Will the engine not turn on when you bump it with the starter?
No. I don't turn the engine long enough for that to happen. Each bump is only a small fraction of a revolution.

You may want to grease or lube where the rids pivot
Are you referring to where the rocker arms slide against the valve stems? Explain.
@@ImpalamansGarage the linkage rods for the throttle. Since you cleaned them they probably need relubed so they don't stick
@@Tigerfire75 oh..... my mistake. Yes. I lubed up the little ball joints on each one upon reassembly with some lithium grease.

I’ve had my diesel for 24 years and I don’t ever recall doing a valve adjustment, is my car going to die now?
Unkown but it might make it run a little better. Valve adjustments on these old mechanical injected diesels are just routine maintenance.

Appreciate you watching. Let me know how it comes out. Using the starter to move the engine to get to the next valve is the way to go.
