The engine never came with glow plugs. The heat from the starter warms it up lol

incomplete combustion on a Diesel is white smoke, Cold Cylinder moving air compressing fuel and it not detonating. on the contrary a similar thing happens when Fuel knock Occurs too much fuel in the cylinder. causes a Very Very loud knocking noise and the engine will produce alot of white smoke but you know the diffrence because one sounds like a rods about to come out the block and the other is when the engines cold..... black smoke on the other hand is from a Not ideal air to fuel ratio. more fuel than air for the 14.7:1 air:fuel ratio its probably a bit too far below that.... some diesels under load can be as low as 12.1:1 AFR... really rich in fuel... and key here is under load as the Engine is free to spin up there fore the turbo charger doesnt really need any time to spool and it does it freely. its why "boosted launching" a diesel is really effective. you're pre loading up the turbocharger with more and more fuel yes expelling black smoke typically. but the turbo can spool because the engines demanding more air for the increased load which also calls for more fuel. Diesels are unique. they're Compression Ignition engines. they're alot simpler in most ways than gas motors, and far far more durable. alot of drag racers modify their engines to incorporate Timing gears instead of a timing chain from the crank to camshaft....... i've not really heard of a Diesel engine that's come without timing gears from the factory..... i've never seen diesel engines over 2.0L displacement with out 4 BOLT mains or more. i've even seen 6 bolt mains on very large engines. and almost all diesels have a bed plate design. so instead of main bearing journals bolted on... when the blocks cast with the mains in it. then the mains are cut in half. and that half uses a gasket and its bolted to the block.... that huge piece of cast iron adds block stiffness and is infinitely more durable than crankshaft main caps. usually held on with 20+ bolts of significant diameter. and almost all diesels are at least 4 main bearings. a good number of gas engines are 3 main bearings. they have a tendency to banana the crankshaft and this will happen around 400-500 hp mark... even some of the weakest diesel designs of the same Displacment the engine can and will sustain 1500 hp or more without any major engine failure.
