hi david, in addition to shiming up the tens., i hope they replaced the
timing
chains,( precautionary) since, you probably dont know how many miles
are on the chains, and it sounds like the top chain is stretched.(provided
you
shimed the cam towers up to standard. you have to measure the head thick.
subtract it from 4.528[std.], and shim up the head that amount). you dont
know if the head has been machined before, unless you measure it. im sure
you know if a chain breaks, at least 2 valves will bend. sorry to be a
harbinger of doom. bob smith

From: mtbdavid2@aol.com> Subject: [Roadsters] Timing chain rattle at start up
(death rattle)> > Hi,> ? I had another non-rebuilt?2liter motor dropped into
my '68 2000.? I ended up using my original head which has been rebuilt (shaved
and cam towers shimmed with B cam).? I went to pick up the car today?from the
shop which installed the motor and noticed when I started the car the dreaded
death rattle.? I had the shop pull?the valve cover and sure enough the timing
chaining is eating into the timing chain hanger when I start the car.? After
startup the rattle goes away, I suppose it gets enough oil pressure after
starting to keep the chain off the hanger.? > > Is there any quick fixes to
keep more tension on the chain when the motor is not running?? I may have been
hallucinating but I thought I had seen a tie wrap on the tensioner to keep the
tensioner out when the motor is not running.? This was on my rebuilt head with
the original motor.? There isn't a tie wrap on there now.? I am looking for
the easiest, cheapest fix to get by for a year or so.? I already spent too
much money buying the used motor and having the motor installed.> > Thanks,>
