I would bet money on a bad head gasket between 4 and 5. Repeat your test a
few times, cold and hot just for comparison. If the numbers continue to
match between the two the gasket is likely at fault.

White smoke is unburned fuel, or water. Since it goes away after a
couple min. it is 90% liklihood to be unburned fuel. That indicates
either low compression, or bad glow plugs or the oddball things, bad
nozzle, broken prechamber tip, bad headgasket between the two cyl. or
the like.
Compres
Set the valves to about 0.010 extra clearance and drive for a bit.
If they were tight, you can get carbon buildup on the stems, keeping
them from closing properly. They will go tight again very quickly as
the carbon wears off, and you still don't have them closing properly.

Really? We're not talking crazy big money to begin with. Rusty's gotta eat too.

I forgot to say how. Pull the plug off of the glow plug relay that goes to the
glow plugs. Test for resistance. Bosch glow plugs should read 0.6 ohms or there
abouts with an accurate meter. Beru will read a little lower (I have Bosch in
one car, Beru in the other.) Any that read open or over 1 o
White smoke is unburnt fuel. Check the glow plugs. Even if one or two are bad,
the light may not indicate it. I had the same problem recently. Rusty will
price match whoever has the lowest price. Currently that is Rock Auto. Buy all
five, I had two bad ones, and another went bad a week later. M
I hope it's not a failing head gasket between 4 and 5.

I've posted a query about this previously but didn't obtain much to look for
regarding my '85 300TD rough idle and serious smoking (white) upon cold
startup. After ~ 2 min. warmup, the idle smooths out and the smoking ceases.
