car making knocking sound.

Me and a buddy of mine got 2 240's both with the ka24de and all stock but we both have noice coming from the vaulve cover, i got mine checked out and they say its something with the timing chains , does anyone else have this problem?

[driftingmy240sx]

all ka's have this problem. its normally caused by the upper guide which can be removed with out harm. just remove the valve cover then the 2 bolts and guide.

Yeah this is what i thought it boiled down to but i took mine off and it still is making that noise , i know its that but i just want to know is that going to be a problem in the future becouse the dealership dont make that part anymore

I was told to remove the side chain guide if the noise persists. I was also told to replace your timing chain tensoiner if you do this step.
