@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
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+.
As long as the oil pressure stays over 5 pounds there is enough pressure to run the engine, believe it or not. My sister has a 93 Cavalier 2.2L with somewhere around 240K miles that started doing this after I replaced the head. I am going today to replace the timing chain, I believe the chain tensioner has broken. I am going to try and tighten the rocker arms upper today, but I suspect it has a lifter going flat. Her car has been making the "lifter" noise for quite some time.
Sounds pretty darn good for that many miles on it. That is probably the hydraulic lifters. I had the same engine, same noise, but it was a PITA to try and change the lifters without pulling the head.... tried to use a magnet. I did snap a rocker stud off thinking it needed tightened and found that a ford 302 had the same studs, lol. Its its not loosing power, I wouldnt worry......
@motorhead45102 thanks man

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

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

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.

Could be bad lifters but, at 313k miles, the cam itself is a suspect as well.
Tiny19812003 1 year ago
@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.
