sounds like you might have lost the rings on one of the pistons.

Please need the groups help. Given: car has 270K miles. Valves due for
adjustment but not over due. Religious filter changes, Mobil 1 Synth.
Timing chain stretch unknown, I have never checked it in 100K miles (I know
a no no)
Was driving on interstate. Heard a "sound" in engine area for about 5
seconds. Imediately noticed power drop off on hills and alot more smoke
from exhaust, white blueish. Once I pulled over idle was rough, allot of
blue smoke. I suspect valve trouble. No bubbles in the open radiator. Car
runs starts but is very rough and no power at all on hills
Action items: Ordered diesel compression tester and 18mm glow plug adapter.
Also will pull valve cover check for valves clearance and timing chain
degrees and stretch. If a valve rod is thrown or bent I may find out by
doing that. I have a feeling it might be bad, but will be hopeful
Any more advise/war stories the list could share with me? Regards Tom
