I am currently swapping out a 617 as chronicled in this thread:
My W123 617.952 Engine Swap Thread
The reason for the swap is the engine doesn't start below about 40 degrees, and I suspect a lower engine type problem.
Here are the details:
- motor and trans have 230K. I have owned since 206K, engine was in this basic condition at time of purchase
- compression: 380 360 380 220 240, numbers do not change with additional oil
- oil consumption: 1/2-3/4 qt per 1000 miles. some leaks...
- above average blow-by, puffs like a train, but doesn't throw the cap off
- i suspect, but have not confirmed, that exhaust gas is getting into the coolant
-- transmission has no issues - replaced the modulator and shifts well
From the engine, I need to take various pieces - I will be taking:
- injectors
- alternator
- secondary filter assembly and clear fuel lines
- couple other small pieces as I need them for the swap, which I will note
The engine has never seen winter, as it is from Texas. It looks really good.
Please PM me if interested. Price negotiable, Id like it to go to someone who needs it. It would be an excellent candidate for a teardown. Id do it if I had the time and space.
The engine is still in the car and running for a couple more weeks if you'd like to come visit it before I pull it.
Thanks,
dd
