So, I can only hear the noise when I rev the engine. Is that how its supposed to be for a rod knock?
It was almost empty, so i added enough to fill it.

Rod knock is usually heard when reving and under heavy load.

A more accurate description would be 'had to add 2 quarts' or 'it was at the end of the dip stick.'

I think that is what the original question was aiming at. :-/

In cars after 1989 the crank case holds 3.7 quarts

Edit: Come to think of it I just fixed a "knocking" only heard when the car was under load. I got a mechanic's stethoscope fro Harbor Freight and went poking around to see if I could find bad noises. Never touch the end to anything electrical or moving. The manifolds, block and valve cover (upper end) were OK and then I touched the EGR valve. :smackface It was knocking. It shouldn't do that. I got a new $1.50 gasket in anticipation of a major clog or failure. Took the EGR valve off and the gasket had blown maybe 1/2" out. New gasket and all is well.

Kinda figured you'ld add enough to fill it. What I was trying to find out was did you add 1 quart, 2 quarts, 3 quarts???

What's more important:

Why was it low in the first place?

I love this thread. Can't wait to hear & see the video...and find-out how much oil it needed to get full.

Meanwhile, although I have one of those HF stethoscopes, I use a short length of hose more often. The stethoscope is great for internal noises conducted through metal engine parts, the hose is great at hearing external noises in accessories.

Take a 3' length of just about any kind of hose from 3/8" fuel line to a chunk of garden hose, stick one end "in" your ear, and probe around with the other end. You'll be surprised at what sounds you can isolate.

For the "crankshaft sprocket bolt" mentioned by Woodie above, listen at the bottom of the engine on the passenger side from the underside of the car. This avoids the biggest risk when using the hose as a stethoscope - the hose could be "sucked-in" by a belt on the wind-up side of a pully - always keep the hose away from fast moving parts where the hose can get tangled and mangled.

good luck!

Sounds like a good idea! :thumb

I'll try that one... but only probe for noises on my car. ;)
