W113: New Life Old Soul, Ch. 8 Engine Stripping

With the engine on the stand, I was motivated enough to at least get the head off of the block to get an idea of how the block looks and whether or not this engine will get some maintenance done on the lower end. 

Removed this last fuel line to make way for the eventual removal of all the engine nonsense mounting to the driver side engine arm.

Removed the oil filter and was greeted with sludge. There was a solid inch of sludge at the bottom of the oil filter canister.

This is my first time embedding video that I took, if it works and you can see it, you'll see the chunks of sludge flowing out of the canister as I tip it.

With the sludge debacle over, 3 allen bolts and the oil filter housing comes off the block. 

Here's a close up of the block portion of this. I was half expecting one of the holes to be clogged with sludge, but that wasn't the case thankfully. 

Started to remove the nonsense on the engine support arm. 

Started with the fuel filter and housing. Filter looks like it was replaced *insert sarcasm*  

Fuel shouldn't be brown, should it? Going to drain and tank when I open the garage door next. If the gas comes out of it like this, I'll be dropping the fuel tank and flushing it out somehow. 

Bottom of the fuel filter housing with the old fuel drained out. A little scrubbing and some acetone or brake cleaner will make this pretty again. 

I'm pointing out one of the hard fuel lines that runs behind the injection pump. Takes a bit of finesse to get this line out, but it's doable.

In a bit of an excited state to get the head off of this engine, I hadn't taken any pictures, sorry! 

The one thing with these old M127s is the fact that there are two small allen hex head bolts hiding down in the head holding onto the front of the block. Don't try to pry or hammer the head off of the block, if it's not moving, there are two of those bolts hiding up front. 

Cylinder 6 is very telling of a few different problems. One being the oil leak at the corner and two being what seems to have been a gasket that failed with some sort of combustion event. 

Close up of the gasket damage. 

It's apparently been like this for a while too, the portions of the head where the gasket was sealing are clean. Can see the imprint of soot on the block. 

And, I'm not liking this too much. Cylinder walls aren't looking too healthy. There's no deep scratching, all of these are fairly smooth. All these are from the engine just sitting still. These aren't vertical markings which would mean something else is being an issue. 
I'm going to put this as many failed attempts to start this engine over a period of many years. Each time someone tried starting the engine it was breaking up any sort of corrosion that accumulated on the cylinder wall. Let this be a testament to "If I've got an engine sitting for X amount of time, what should I do?" Fill the damn cylinder with oil and let it sit, then try turning it over. Absolutely do not try turning over a dry engine. 

This is where I left off. Next installment should be injection pump removal and both upper and lower oil pan removal to see what's happening down there.
