FInally the smoking gun- rod bearing in cylinder 1

 When fixing things, especially if you are not 100% positive on your diagnosis, it's common to take it apart until you find something that looks broken and then fix it.  It's always my worry that I'll take everything apart and never actually find anything broken...  

 That's actually what happened the first time I did that with a bad starter motor.  I took it all apart, looked at each piece, and then put it back together.  Danged if it actually worked after that...  As it turns out it was simply all gummed up and by taking it apart and putting it back together I did indeed fix it...   that was a learning experience!

For this engine, though, it was knocking really badly.  And lo and behold, once the head was off, we could do a pretty definitive diagnosis!  Here's a 43-second video.

Weekend's progress- the driver's side...

 Just a quick shot of the weekend's progress.  managed to remove the turbo, manifolds, oil lines, starter...  ready now to pull the head!

Pulling off a few more parts...

 Today I got the injector pump, rocker arms, push rods, and tappet cover off.  All boxed up and nicely labeled.

What the front looked like (timing-belt-wise) before I removed the injector pump, timing belt, idler pulley. 

Rocker arms, pushrods, and tappet cover going into the box.

Current status as of the end of Valentine's day 2021.  Next up is the other side of the engine- turbo, exhaust and intake manifolds, and whatever else is down under there. 

New Grain Mill mounting

Finally got the grain mill (a MaltMill from Schnmidling industries)  integrated into my main brewstand, instead of being freestanding (really, resting on a 5 gallon bucket).   I can now mill directly into my strike water- so milling and mashing-in are the same step.  Saves time! 

Control side, showing the hopper (still small, I need to feed it about 5-8 times during mashing in), the power switch, from where I stand for mashing in. 

Drive side.  I stand on the other side from this!  otherwise I'd definitely have a guard on the belt and pulleys. 

Full context.  The mash/lauter tun is the highest point, with the grain mill above.  The brewkettle is from Spike Brewing on the left.  The hot liquor tank is lower right, in this photo being fed with hot water from the kettle.  When I am able to get 220 VAC to the garage, I'll electrify and PID the HLT which will make life easier... 

This week's C223T rebuild progress

Well, it's not really a rebuild yet- it's still a teardown.  But this weekend I got all of the fuel lines, wiring harness, glow plugs and harness, oil filter housing, pressure sensor, and some coolant, oil, and breather lines off the passenger's side of the engine.

 

That's before I took most of that stuff off.  Took this and a lot of other shots to make sure I know where to put things back! 

Now that passenger's side looks a lot cleaner...  Just the injector pump left.  Need to take off a few other things while taking care of the timing belt- like getting the rocker arms off.  Since it's an interference engine, I don't want to accidentally knock a piston against a valve if I move the crank accidentally without corresponding movement of the camshaft.
