The ball is supposed to come out the side. It has to be installed,
after all!
White smoke is poor or non-combustion, so either you have a serious
quench problem or a bad injector, or low compression on #6.
Note that a cracked head will do exactly this -- coolant will leak
into the cylinder and cause it to quench until you heat it up and
blow out the water. It also leaks in while running, and causes
serious glassy carbon buildup on the piston and head, and that carbon
will interfere with combustion, too.
Are the lifters for #6 good? A dead tappet will cause low
compression, or worse, trap exhaust gasses causing poor combustion.
Also check for an EGR valve stuck open, although that usually causes
severe black smoke on acceleration.

After evaluating the slide hammer, I realized that it was 3 pounds,

help. So with a 10-12 lb tranny cluster gear and a 1/2 steel bar (3
feet long), we constructed the MOTHER OF ALL SLIDE HAMMERS.
Prechamber came out in less than 10 slides.
UNFORTUNATELY, the prechamber does NOT seem cracked, so the search
continues...WHY oh WHY does this 603 run like crap until it really
warms up....tons of smoke, lots of noise, missing on cylinder #6.
(FYI, timing chain is OK, injector timing is OK, compression is OK,
injectors are rebuilt (but not balanced), glow plugs all work
great). I am stumped.
By the way, what should the prechamber look like inside? This one
has a coating of carbon, but the holes are all clear. Also, it
looks like the little ball can be tapped out the side of the
prechamber...should that be done to inspect for cracks? The FSM
says nothing about doing that.
Thanks y'all.

Oh -- he offered the usual $500 several times - my son is determined
to make it "right" though.

Why didn't you offer $500? I'm confused, you condemn his
son's car, but
don't lowball him? Is there some special (Banned) relationship here
that we
don't need to know about? :-D
