Just bought a 2002 GT Mustang two weeks ago and the second day I had it
when I started it up I got a slight noise at start up. This was done after
the engine sat over night. There is a noise that goes away soon after the
engine warms up. is this noise serious ?? If it is i got a warranty I
purchased with the vehicle. Noise sounds like a slight knock. Is the oil
not getting to the parts soon enough? Is there a cherck vavle that
supposed to hold the oil up there so it won't have a dry start?

You can check with the dealer for a little extra peace of mind (they will
want to hear the car on first start of the day) but you will find that some
noise is considered normal on the modular engines. These pistons are pretty
much a skirtless design so there's not much to stabilixe them in the bore
until they start to heat...

My Y2K GT has knocked on start-up since day one. At 10K miles I
switched to Mobil 1 10W30. While it reduced valvetrain noise on
start-up, the light knock is still there, lasting one or two seconds.

I hope you are not using FRAM oil filters. I had the same symptoms
when I tried a fram filter.. Went back to motorcraft filter and
startup noise was gone.

Agreeing w/RT, I've only found three oil filter brands that work well
with the Fords I have...Ford, Purolator and Mobil 1 (in order of
preference).
