1984 300SD smoke during Wide open Throttle (WOT)

Hey guys and gals.

1984 300SD
142k miles
I have had it about 8 months
I have changed both fuel filters and purged about 5 months ago.
It has a fairly fresh oil change and filter about 3 months and 3500 miles ago.

It starts and runs very easily and well.
It kicks down and shift correctly (sometimes a little jerk on upshirt but really minor)
All my vacuum stuff works

When I drive the car it start and warms up to 1/4 the way above 80deg on the temp gauge and stays there if it matters.

transmission differences, 300Dt / TD / CD / SD (W123, W126)

I'm looking at cobbling together an engine and tranny, a car with a blown engine, and a car with a wasted tranny..

The problem is.. The car with the wasted tranny (300SD) is in Arizona.. The car with the wasted engine (300Dt) is in Missouri, and the available donor engine transmission is in Michigan..

..Oh, and I'm in Ohio, closest to the engine/tranny, but even that's 70 miles from me.

560sel ignition coil

Have a 1990 560sel with 127k miles. Want to start changing the oil myself via the dipstick. Other sites say that it's best to disconnect the ignition coil before cranking the engine over after the change. This prevents too much strain on the timing chain. Have a repair CD but the coil is not behind the EZL as shown on the diagram. Looking for the location of the coil. Thanks.
