Here's what the 2003 TSB said:
"Purpose
The purpose of this bulletin is to communicate updated service procedures to the
timing chain and timing chain oiling nozzle due to design changes that have been
made to both components. All timing chain kits now available in service will
include the oiler nozzle. This new nozzle has higher flow rate characteristics
that will increase oil flow to the timing chain under low RPM operating
conditions. Whenever replacing a timing chain, it is important to replace the
oiler nozzle."

So it sounds like you don't have adequate oil pressure at idle to properly oil
the chain with the original smaller nozzle, and it's the people who sit at
stoplights or drive like grandmothers who have the problem?
