I actually had this happen to me on one of the CSX-T's I owned. Not hot
rodding it or anything... sitting at a stop light on my way the eye doctor
one day. Just sitting there the car stalled... found that the cam broke -
just snapped! At that time I had learned that there were quite a few others
that had the same issue with 1988 cams... I still have the both pieces of
that cam... one of those things that I saved for some silly reason!

I had a roller cam break between the intake & exhaust lobes of the #2
cylinder in my '88 Daytona Shelby TII in the middle of winter in Illinois,
on a very cold day (about 0 degrees out), on a country road in the middle
of
nowhere, while teaching my 17 year old daughter how to drive a stick. She
thought that something she did made the car quit...couldn't have been the
jerky take-offs and stalling stops...LOL. Fortunately, a farmer drove by
and let me use his cell to call a tow. Once I got it home I actually got
it
to run for about 30 seconds on 1 cylinder. Then I noticed between the cam
sprocket and the head the polished area of where the oil seal rides on the
camshaft. Should not be able to see that!!! Installed another cam and it
ran fine. Sold it a year ago and it is still running great.

Subject: SD> Ever break a roller cam?
Last year my sister had her high mileage car break down for good and she
was
in need of a new daily driver. A local friend knew of a good deal on a 2.5
powered minivan so I thought it would be a dependable vehicle for her. I
use
one myself for m company minivan and it's been quite good with me.
It's been pretty reliable thus far but recently she's been had an unusual
problem that's been making her feel that it may be headed for a serious
and
expensive engine repair (which she can't afford since she was laid off
recently).
Last month without any prior warning signs it stalled out and wouldn't
restart. I went to take a quick look at it for her and discovered it was a
pretty simple problem, the timing belt had broken. Well that was common
enough
and it wasn't complicated or expensive to repair so I didn't feel it was
an
unusual.
The repairs went fine and it was back on the road and running fine within
days
but what happened next I thought was real unusual. Again it stalled out
and
wouldn't restart. I pulled the inspection plug from the upper timing belt
cover and the upper cam gear was turning so I knew the timing belt was
turning.
She had it towed to a shop where their immediate diagnosis was a blown
head
gasket. This made little sense to me since there was no warning signs and
it
had no history of or sudden last minute overheating or smoking. They said
they
ran a compression check and two cylinders were getting little to no
pressure.
I didn't feel that was the right diagnosis so she had a mechanic friend of
hers work on it at his house. He somewhat agreed with their theory but
when
the head was pulled the head gasket looked perfect. Upon further
inspection
(which should have noticed once the valve cover was removed) he discovered
that the roller cam had snapped between the area around the last 2 lobes.
In a regular stock setup without extreme driving conditions I don't seem
to
recall seeing camshafts breaking like that. I supplied a decent 2.5 used
roller cam that he reinstalled the head gasket & cam and it's back to
running
normally.
Someone told her that this was a sign that the bottom end of the motor
would
be going out soon and the engine was on borrowed time. I was thinking that
the
cam breakage was just a fluke and possibly due to stress caused by the
timing
belt breaking and wouldn't have a direct influence on the lower end of the
engine. Has anybody had any experiences with camshafts snapping under
routine
driving? If so are they having other engine problems later?
