engine noice please help
noice# 1-i have this slight nock sound every morning when i start the car.it only happens with the car cold once it gets up to regular temp the knock goes away.
noice#2- this one really bothers me.when i accelerate from a stop i get this noice that sounds like if i have a chain draggin.the noice will go all the way from 1st gear to 3rd and then goes away,sometimes it only does it in 1st and 2nd sometimes is louder than other times but i noticed that is allways when going from a stop.
please shed some light on me on what could this noices be and how can i get rid of them.
i went to a shop about a week ago and he said that it can be the pulleys making noice but before i go and change them i would like to see if anyone has ever experience something like this and how did you get it fix.

Sorry, it was assaulting my senses. Here is the translation:
Noise #1 - I have this slight knocking sound every morning when I start the car. It only happens with the car cold, once it gets up to regular temp the knock goes away.
Noise #2 - This one really bothers me. When I accelerate from a stop I get this noise that sounds like I have a chain dragging. The noise will go all the way from 1st gear to 3rd gear and then goes away. Sometimes it only does it in 1st and 2nd, sometimes its louder than other times, but I noticed that it is always when going from a stop.

Maybe you need to do a little proof reading yourself.

Getting back to the issue (keep fighting over his spelling, morons)...
The knock (if it's what I think it is from your description) on start-up could be oil starvation. You don't mention what engine you have but you need to be sure you have the right viscosity oil in the crankcase. From your user name, I'll assume it's the 4.6L so 5W-20 is what's recommended.
The chain dragging noise could be a number of things but my first thoughts are engine ping. Since you've changed the tune and it still occurs, it MAY not be that UNLESS you're using too low an octane fuel. Have you tried a higher octane (93) to see if it goes away? Otherwise it could be anything from a rattling heat shield to a loose exhaust clamp... you name it.

After some additional thought...
Regarding noise #2, try to take note if it occurs in a specific RPM range. There were a rash of threads in the past regarding a "rattle" of sorts around 1800-2200 RPM (the RPM range varied for each individual) attributed to heat shields and the axle back pipe clamps. The RPM range in which it occurs may give a clue to the cause.
