350 sdl
 

I am looking at buying a 91 350 SDL that recieved a new factory motor in 2000. I am told that the new motor does not have the "rod bending" issues of the old. Is true? Otherwise, are there any other issues to lookout for?

Many thanks!

I would not assume that the new block would necessarily not bend a rod.

That is correct the factory replacement engines do not bend the rods.

As long as they used the updated connectiong rods, then they should not bend.

Personally I would not trust that "rule".

I am pretty sure that several folks have posted here with factory replacement blocks with bent rods.

Buy it
 

My 350 SD is great.

You should buy one.

I'd buy it, it probably has all the updates.

Where is this car located? I would take a look.

My 1991 350SDL purchased new by me has 197K miles on it now and has no signs of a bent rod. Engine was built 12/91, don't know if it has the updated rods or not. Has been a terrific car.

Production of MY-1991 Mercedes ended in mid 1991. If the engine was produced 12/91, it is probably not 12/91, but the 12th week of 1991.

Oh, and I'd buy a nice 350SDL in a heartbeat. I'd keep a 3.0 short-block around for a spare perhaps, but I love the cars.
