my peugeot didnt smoke... if you have worn compression rings but good oil rings you wont burn oil as the oil ring still sweeps the oil off the cylinder wall on the intake stroke so it doesnt end up in the cylinder to burn..
compression smoke would only be an issue perhaps on cold start and if the compression were low enough that cylnder was having trouble burning fuel..
I would think thoiugh that youd see some blow-by smoke from the tube at idle... on my peugeot I rember a pulsation of blow-by smoke from that tube at idle.. not alot but some.. since it was a pulsation in tiune wit hthe rhythm of the engine i surmised that it was an issue in one (then 2) cylinders and not engine wide... it smoked on startup a bit more than it had previously...
of course that was a little 4 cylinder car diesel vs a big truck engine like we are dealing with.. but it was a mechanical diesel with the Bosch fuel injection system..
you almost need a go pro on the front bumper pointed under the bus to see what the blow-by tube looks like when you hammer a heavy hill....
