Amazing rebuild

After forgetting about it I stumbled on this amazing rebuild that I'd bookmarked long ago.  It was my bible during some dark times a few years ago.  I figured that everybody has seen it, but that's probably not true.  So if you haven't, enjoy!  Cheers,

Lovely car! I'm not sure why he rebuilt engine with only ~140k on it though. The black paint on engine is a bit too shiny for me despite the "pop" it presents. I thought it odd he put the valve stem seals on before inserting the valves which could damage them. 3-5 photos of each item makes it tiring to keep viewing.  Chassis # 649 and VIN 6235.  I'm fascinated why chassis would hang around for several years before being built. Anyone know when they started putting the high voltage label on the air cleaner?  And why the valve setting label that goes on one or ?two? valve covers are rarely seen. Never seen cotter pin clamps on radiator overflow hose before.

Anyway looks great and owner seems to know what he is doing.

Maybe he hydrolocked and blew it up.   ::)

There is quite a but wrong with this build cosmetically, but I'd gave to give an A for effort and a D for cosmetic research.  Regarding the cotter pin style clamps, Mercedes quit using those in 1968.  This car should have the standard solid banded GEMI clamps.

A for effort, for sure.  Over time these cars seem to be divergent evolution in action after people cobble together different ways to fix stuff.   Other stuff besides cotter pins?  Cheeers,

Raueda1 - Thanks so much for your kind comments about my car.  It's been a labor of love since I purchased it in 2012 and I continue to drive it regularly.  Appreciate your kind comments.

Perhaps I can shed light on the other comments/questions.  I had the engine rebuilt after a cam bearing failure.  We weren't sure if metal had gotten into the engine and the only way to repair it properly was to rebuild it.  I'm not a mechanic, so please don't go overly technical in responses.  My mechanic, Steve Ady, has been working on Mercedes for over 35 years and I rely on his expertise and guidance at every turn.

When these photos were taken, the car had just come back from being detailed.  Hence the shiny looking black finish on the air cleaner.  Once the detail dressing was washed off I can assure you that the black finish was as close to stock as humanly possible.  As for the cam covers, I did opt to have them powder coated.  You would be correct in saying this isn't stock, but I hate looking at 6.9 engines with flaked off black paint on the cam covers.

Wow, there were so many engine rebuild photos that I gave up, not sure if there were other good rebuild stuff after.  But I bookmarked so I can look again.  Beautiful car, I'm sure it feels worth the effort when driven.
