Hi every one

I have a 85 300D sitting at home with no engine.
So I decided to do something about it.
The question was to rebuild a engine or to buy a used one.
I bought a used one, actually a 83 parts 300SD with a running engine and 220000 miles on the clock.
After I installed that speedo in my 560SEL diesel conversion I found out that the odometer stopped working at 220000 miles.
The engine wasn't running to bad in 300SD, but I had to change a couple parts to make it a 85 300D engine.
3 injectors didn't pass the pop test, so I replaced them with better ones.
All valves were tight, but not to the point to cause compression loss in a cold engine.
After I installed the engine it actually started up, on wonder at 110+ degree outside temperature, but it had not much power and it smoked a lot.
So I removed the ALDA, that gave me more power, but didn't do any thing to the smoke.
Also the engine temperature reached the boiling point after a short test drive, in spite the fact that I installed a 75 degree thermostat.
Today I did a compression test.
280,400,340,260,320 1 to 5.
Then I did a leak down test and found that cyl. 1,3,4,5 blow out of the exhaust, and cyl. 4 and 5 out of the intake valves.
It's hard to tell the difference in blow by through the piston rings.
Well, I think I have to remove the head now and see what is going on.
At leased I have everything I need to do the job on hand.
I hope that will fix some of my problems with this engine.
And what do we learn from this???????
