But wait…there is less???

As the Christmas Spirit draws near and Pistonheads relax with thoughts of good vehicular cheer…screw it, I'll get to the point:
Can timing chain rattle on start-up magically resolve itself after a mere tune up?
Sajeev continues:
Yes, after changing plugs, fuel filter, PCV valve, and a very necessary cleaning of an ancient K&N filter. The vehicle in question is my lightly-modified 1995 Lincoln Mark VIII LSC with 180,000 miles.
The early 32-valve, teksid block Ford V8s suffered from an obnoxious (yet harmless) timing chain rattle on start-up. I've owned this car for 11 years and, like all of its ilk, the rattle almost always rears its ugly head. Even after switching to Mobil 1 Synthetic.
That is, until this tune up.
Snakebitten.
I've been driving the Mark for 100+ miles over 4 days to-and-from work and Christmas shopping destinations: the timing chain has yet to rattle on start-up.
It's the textbook definition of "added perk" to go with the improved idle, extra power and 1-2 MPG fuel economy improvement normally earned via tune up. But it's still running the same oil and the outside temperature/weather hasn't changed. This makes absolutely no sense, and Google agrees with its lack of click-to-quick-resolution.
Perhaps the Mark remembered what the MKS looks like, deciding to straighten up/fly right as it's the last Lincoln that people would maybe-kinda give a crap about? (oops, sorry LS fans)
Off to you, Best and Brightest.
