fresh engine problem
just got a new engine back in my truck , the engine has malhe marine pistons , colt 181-210 cam , 60lbs valve springs, studs , dpp 140's , 181 dv's ,160 pump, adjustable pump gear , timing set at 16 ,
problem is white smoke and popping , i did a 5 min no water break in , engine sounds ok at 1800 rpm ,it's when you go to rev it up it pops , hold the rpm and its ok
i am going to try more timing 18-20 and bigger dv's and check fuel pressure

Sounds like your timing is off.

Was it timed by the right chart? I helped a friend out that had his pump timed in a diesel shop late at night and they used the wrong chart for his pump.
Also I have seen that happen with broken valve springs. I would definitely check fuel pressure and check the timing again.

I don't understand this. I've never had a p pump that was keyed. They are a tapered shaft press fit.
