Ouch, that it horrible - Ok, I'm going to have nightmares tonight. But
honestly I would think that there must have been some advanced warning
that something was wrong (like running on 7 cyls)? 

I have almost 160K miles. I changed valve cover gaskets ~ 1 year ago,
and the cams looked beautiful (as much as I can tell). The motor runs
and sounds great, but I have been thinking about doing a chain,
tensioner & rail job for a while.

Anyone know about how much I am looking at in parts, and approx. amount
of time it takes to do the job? (I'll do it myself - no issue with
that). Any special tools needed? I know, parts cost << $ than a motor,
but I'd like to get an idea. $400, $500?

If the cam lobes look good, as they seemed to me, I don't see a reason
to replace them (lifters, valves, etc). Maybe valve seals - but I don't
notice any oil burning. I know, prevention costs less than replacement,
but what level is really needed.

What kind of life do you guys (and gals) out there have on your motors
with what level of maintenance/rebuild? 

Thank You,
