1290 DB Case Engine Rebuild

ml44special · May 21, 2015

Guys, after rebuilding the engine, injection pump and injectors, when we fired it up it puffs white smoke. First I thought injector, then I thought valve adjustments, and now timing. Nothing seems to be working, any thoughts or ideas?

I am willing to get stuff tested and check out but it is just frustrating because we have not had an issue like this before.

Does it run at all or just a weak attempt? I pulled a dumba** move on our 1290. I didn't understand the engine designation as it was not the standard C.I. of the engine. Ordered a kit for a AD 4/55 which I had heard of (219 C.I.), but I needed the AD 4/49 (196 C.I.). Pistons are 1/4" shorter for the 219 as it has a 1/2" longer stroke. When I went to start it all I got was white smoke. Only had the compression of a gas engine and it sounded like it. Were the pistons almost flush with the top of the block when you put it together or 1/4" short of that?

If it runs, get it up to temperature for a few hours working it hard.

I'd bet it clears up.

Well it runs, starts slow, but it just literally buffs white smoke like one clydiner is not firing.

Loosen the injector lines one at a time when running to try to isolate it to a certain cylinder. Then pull that injector.
