Bought a 97 12 valve with 292xxx should I be worried about miles drove truck 300 from where I bought it

No just your head gasket, these motors go over million ml if taken care of.

1989 to 2002 Dodge Cummins engines will do over 1 MILLION miles without a thought.

 

Its the Common Rail 2003 and up that have a hard time getting past 100k to 300k without eating a piston from failed injectors.

Last truck in my yard lost $6,000 worth of engine after #6 injector took piston and ring out for #6 cylinder. Need to be bored and sleeved. This all happened with the factory injectors at 112K miles on the clock. Factory injector stuck open hosed the rings and ate the cylinder. Most people don't take the warning signs of the hard starting serious or the grid heater light always on Dodge's way of telling you that you have failed injector(s). I've got another one I continue to warn the owner to park the truck because the grid heater light is on. Doesn't listen though. When he eats the engine he'll be all pissed off.

Wouldn’t a stuck injector cause hazing out of the exhaust at idle

No. Typically the only clue you get is a hard starting the engine runs as normal no change in smoke typically.

My truck needs a little throttle to start but ik some of these trucks are that way it’ll start without throttle in couple of seconds

97 is a P-pump and don't have any cold start idle for them so yes its normal to give throttle to start a 97 Dodge cold. This was resolved in 1998.5 with the VP44 where the ECM kicks the timing up to 20* BTDC and ramps up idle speeds based on ECT temperature. Once warmed up the timing falls to 12.8* BTDC. Something P-pump can't do.

I didn’t know that I just know it doesent really have a hard start but it doesent take a minute to start either
