Tired 87 560sl due for engine

A while back I purchased a 560sl to join my mercedes fleet. I thought it was a good deal, but it has white smoke upon start up. I am currently doing the repair/replace analysis I began thinking that while I was at it, it would be nice to get a little more horse power out of it. In researching the internet, I found that the sl 560 was de-tuned for the US market, that the SEL/SEC has more horsepower. Also when investigating, it appears that used sel/sec engines are less expensive than the sl motors.

1981 300SD transmission problem ??

Yesterday my SD suddenly started not shifting beyond second gear. In addition, it remains in 1/2 regardless of where the gearshift lever is placed, including reverse, but does not lock up the drive train, i.e., it is not actually shifting into reverse. As a result I am surmising that this is a valve body issue rather than a gear train one. Has anyone experienced this before? If so, what was the solution?

Thank you in advance

1985 300SD Disconnected blue Wire near battery

Found a disconnected blue wire near my battery. Can't figure out what it goes to. The previous owners installed an aftermarket radio so I'm wondering if it is from that or if this wire was disconnected from somewhere else. I'm having difficulty tracing it to figure where it is going. Any help is much appreciated. The wire comes through the firewall into the area near the battery and is blue.

w115 Engine swap

Quick Question - Can I remove the engine(dead motor) from a '75 W115 300D and replace with a long block turbo OM617 (will not be using turbo set up-just long block minus turbo) and then swap over all the W115 specifics, oil filter housing, IP,manifolds etc,motor mount arms, etc. Easy or is there something I am forgetting? Thanks!

1984 300 CD Rear Bumper Corrosion

removed the rear bumper and associated rubber trim pieces because the black trim piece running the length of the bumper was loose. Further investigation revealed it's time to conduct some corrosion control on all the metal parts.

Looking inside the bumper one bumper shock has separated from the bumper. I plan to just drill holes and bolt the bumper and shock back together. However, the bumper is severely corroded where the bumper and bumper shock contact, possibly a case of dissimilar metal contact.

1975 300D Wouldn't Start

After approximately 2 weeks of sitting, I started my 75 300D for a few minutes to move another out of the garage. Then about 1/2 hour later I started again to move back in the garage (ran engine for no more than 2 minutes). Next morning she wouldn't start. Would crank and blow black smoke (more than normal) but wouldn't start. Pushed out and let sit in the sun for an hour. Restarted, runs fine.

Any ideas would be appreciated, thanks.
