Rather than keep creating new posts for all the little thing that come up I figured I create this summary thread of my project to revive a 220SEb (W111) from 1962 aka "Finnie". Engine number M127.982-22.
I acquired Finnie in October 2016 for a laughable $1800 through Gumtree - no title or papers but not registered as lost or stolen either so I took my chance. As you might imagine for that price, the car had been neglected. When I drove down to pick it up it was standing in a backyard in knee deep grass merely covered by a gazebo that had definitely seen better days. Just getting it into the shed at home was a 6 person effort as the brakes had completely seized and the car wouldn't budge on its own even on a downhill street. Part of the reason it was so cheap was the fact that its cylinder head was missing. By sure luck, a workshop on the Gold Coast about to go out of business was clearing old inventory and I was fortunate to secure a complete replacement engine for $550 the following week.
Starting out with nothing but my bare hands I had to purchase a large range of tools that set me back $1800 so far. So pretty much the same price as the car. But there's just no way around decent tools for a project like this. For anyone interested, I'm keeping track of all the expenses in an Excel spreadsheet.
Progress to date:
Not knowing anything about the original or the replacement engine I decided to do a half-decent rebuilt and started with stripping the replacement engine down to it's bare bones. Plenty of learnings along the way but a combination of English and German workshop manuals plus your support on this forum eventually got me there. Next was removing and stripping the original engine. Everything went smooth as having done it before until it was time to lift it out. Turns out two f*** bolts connecting the transmission housing with the engine were just below the firewall and impossible to get to. Approx. 4h of coursing and bruised knuckles later I gave up and accepted the transmission had to come out too. A shitty job as it meant working under the car on the floor with bits of transmission oil and built up grease raining down on me with every twist and turn. But eventually I got there and managed to get them out together.
This weekend I brought both engines and the one cylinder head to the machine shop. We're looking to keep the oversized pistons from the original block that was worked on before and make them fit the replacement block. Crankshaft was still looking good so that will see some clean and linish. So in terms of parts I should be alright with new main and rod bearings plus a full set of pistons rings. Cylinder head remains the unknown but looking at a pressure test as well as supply & fit valve seat inserts. If not done before, I wanna make sure I can use unleaded petrol.
Immediate next steps
Degrease, clean, sand, prime and paint engine bay. Bit undecided whether I should remove all parts and get it sandblasted or just sand and prime it by hand.
Get transmission and clutch serviced - Mercmad?
- main bearings
exhaust manifold gasket
Also got a spare engine block, crankshaft and pistons now if anyone is looking.
