valves rattle when you start the truck. it then rattles every time it shifts from 1st to 2nd and 2nd to 3rd.it sounds like timing is too far advanced. would it be a senser,also you here a knock by no-1 that sounds like wrist-pin or connecting rod.milage is 235 k.burns 1 litre of oil in 2 k.

Has the check engine light come on? Do the valves only rattle at start up? Also, are you using a quality fuel?

If the rattle seems to be as you described, my first guess is a knock sensor. However, without having the computer scanned, that is a guess.

One time, you may want to try better gas. It may help. Also, since they charge so much to have it scanned, you should purchase an OBDII scanner. The basic ones are around 60.00.
