That doesn't sound too good.  If you haven't I'd recommend a full tune up.  And are you excessively losing fuel?  If you are, do a compression test and leak down test.  Strange noises are sometimes normal, but ultimately they are b/c of metal/metal contact, which is bad in the long run.

well, to one of ur noises orange-grey, there are 2 guides for the upper chain, the upper most on, and the one on  the right of the chain.  It is recommended that u remove both, i had the noise and after removing both, it was gone.  The second one, the lower guide on the upper chain involves mroe work to get to, but is worth getttin to b4 i can cause damage.  Its only an hour or so +/- job to remove.

and some of those other noises, not sure by ur description, could be heat shields that are loose and making noise. have someone rev the car to those areas and try to specifically source the sounds.

also what octane gas are u using

just some ideas

Check your damn oil pressure. I developed this problem and all of the sudden notice that I had been driving around 2 QUARTS OF OIL LOW.

I have a KA24de that sounds like this. with exhaust sounding like a rattling noise as well..

YouTube - 240sx KA24de problems: sticky valve lifter tick

same problem as yours?

I had this exact noise.. Take your valve cover off, and check the TOP guide for the timing chain, see if its loose.. Nissan OMITed it, so good luck on finding one there. Then flip your valve cover over and see if it looks like something has been hitting it
(you know where the timing chain spins around.)

Thats what the noise sounds like.. Like i said i had that exact noise, and that was my problem

I really appreciate your input. I'll check this out and give everyone an update as soon as I get a solution

ok- for clarification, the single cam (sohc) ka24E engine in 89-90 s13s has hydraulic lifters, and they cannot be adjusted. the dual cam (dohc) ka24DE engine sold in model years 91-98 has valve lash that can be adjusted, but it is labor intensive, and requires the use of feeler gauges on a warm motor, and a micromoter. plus you have to buy replacement shims of the exact size for any valves that are out of spec.
