You can, but if you're taking the head off, you may as well put in new seals, seats, grind the valves, put in new retainers, and throw pistons and bearings at the thing...It won't be very expensive and it will be like new afterwards...

Not very expensive is not a term I would use in describing all the work above.

Most likely most of the above will not be needed, but if you take the head off you should definately have a professional machinist check them for conformance to mercedes specs for usable parts.

1981 240d (engine donor 1983 240d) recently rebuilt engine hurray! - No more.. fought a tree and the tree won.

pearl black 1983 240d 4speed (Converted!@$$%) atleast the tranny was rebuilt.

$1288.86 for a set of Mahle pistons

I'll run it after I check the time chain and fix any oil leaks....

"Someday" I'd like to rebuild one, but I'd rather drive em.

Pistons alone will be $1200.
That's expensive.

Then, there's the rest of the rebuild. That more expensive. I don't think you quite understand the rebuild process on these engines.

Retail for the pistons might be $1200.00 wherever you are, but check around a little, I've found them for as little as $400.00 for a complete set, (Mercedes, O.E.!!) in the very recent past for one of my 79 300CD's. I fully understand what goes into building/rebuilding one of these engines.

Last one I did, pistons were $100 ea for OEM. The rebuild cost me about 3K but that includes new radiator, starter, alternator, belts, clutch parts. Really nice too be driving a car with an engine you've seen the inside of
