Series 60 Question

We recently purchased a 1999 KW W900L with a series 60 detroit in it. It has been sitting for about 3 years. Here is my question,,,,, So we got it home and put it in the shop. About every other time we start it it has quite a bit of white smoke coming out the stacks. It is the type of smoke that your eyes start burning within a minute or so. (Shop is fairly small 40'x40'). What has me baffled is that it doesn't do it all the time and it doesn't seem to be temperature related. (outside temperature or engine temperature). The engine sounds good. No obvious knocks or misfiring noises. Any ideas on what might be causing the excessive smoke??? Thanks in advance.

I'm figuring it's a DDEC III 12.7 or DDEC IV 14.0L, in any case it has a injector bleeding down and it depends on where the rotation stopped and cam lobe is on the injector that bleeds.

Next time it does that pull the hood and check the manifold where the turbo bolts on. Mine did the same thing and when it did it was all wet with coolant around the turbo mount. It had a leaking injector cup. Funny it didnt do it every time!

The fix for that by Detroit was a large o-ring placed in the injector bore on top of the injector sleeve in the head. Install injector with new o-rings and torque down, no more leak.
