Chevy Cavalier 2.2L ohv engine noise

This is a 1994 cavalier station wagon with 313,315 original miles. Motor had a new timing chain and belt tensioner replacement.
The engine still has a knock and it to me is sounding like bad lifters, cause i checked the tighness of the rockers and push rods and the rocker arm nuts are as tight as they can go and it still has some play in it, it seems like the lifters isn't holding oil pressure.
Now can anyone tell me what they think it is, and if what i got is correct.
also i tried using a sethoscope (use to dectect origen of noise) just ignore that parts as for one i didn't have it on the mic on my phone and you probably wouldn't of heard any different.

Use some good synthetic oil & if that don't help you may have spun rod bearing..

@MrVetis no its not a spun bearing, im still driving this car today, and when i put on a head gasket i found out that the knock is comming from cylinder 2, the bore in the piston for the wrist pin is too wore out allowing the pistion to tap the head. I didn't fix the piston, considering the age, the amount of money needed, and the piston and head is damaged and just not worth fixing anymore, i know it sucks but when you don't have money you can't do a thing

Also I don't have that stupid fat can on this car, im over that dumb stage of owning a 4 cylinder car.

Could be bad lifters but, at 313k miles, the cam itself is a suspect as well.

[motorhead45102]

@Tiny19812003 yeah, but i know the oil pressure is 60 psi cold and drops to 20psi at idle and goes back up to 50psi while driving.

@motorhead45102 thanks man

Lifters not pushing oil as it compresses, sounds like lifters are not cooperating

[rcjg24]

that is a tired engine. run thicker oil in it.

sounds like my car except mine isn't as constant as that.. check out the video i uploaded today

Update on what fixed my sister's car. After installing the new timing chain and tensioner the noise is completely gone, the car has never ran so smooth and quiet. I did end up replacing the whole cylinder head also because of bent valves, found a whole 96 model head for $40 and the new valves alone would have cost me $150+.

My car does the same thing it is a 97 with 234000. From what I have been told and read they all do that just something unique to that motor design.
