Question about 1996 Geo Prizm
Oil looks good and no oil pressure alarm going off some think it has pressure
Knocking is a big thing, its a cry for help.
can be minor to horrific
knocking parked? or only driving.
in neutal or park?
knocking hot block, or cold block or both? at what RPM>/
only real oil pressure gauge works, not the idiot lamp
when the lamp comes on at 3-5psi, the war was lost.
my 96 makes 55psi cold just cranking, want a video of that?
find the knocking first.
if can ,be knocked , parked.?
id check oil pressure. real.
use a $5 stethoscope. find it.
drop all belts. to see if an accessory device knocks. (5min test max cold to start, yes, water pump dead)
PS/AC/ALT dead too.
listen at valve cover. coming from there.
is the timing belt is old over 60k thy all shard and some knock load hitting that cover, it a for sure thing, skipping the 60k mile service point,
exhast header collerctor fange gasket , bad, allowing bang band bang as the 2 flanges pound themselves to death.
the top of the engine, see induction pips. (AIR) those mounts for sure can bang away, bolts missing.
1 overheated the engine so bad its pinging? knocks up hills?
2: say exaclty when and not you get the knocks.
