Default Get on your stethoscopes...

So I've been doing some small maintenance... started up my car and it sounded like someone dropped a rock in the cylinder...

It sort of comes and goes, sounds like its coming from the cam or the piston head.

It will disappear for a second, then come back

Give me a heads up if this link doesn't work. Had to use google photos because youtube was stuck in a processing loop and wouldn't upload.

update, seems to go away at idle after warming up a bit, which leads me to piston slap. It's consistent on revving it.

it's a 94 squirter motor.

Glad to hear you figured it out, the video also worked for me without issue.

My car had a very tiny amount of piston slap. When it's running rich with cold engine you can hear it slightly, when it's running leaner (difference between remap) it's not making any piston slap noise. Maybe it's running a tad rich, washing away a tiny amount of oil?

alrighty so I had checked the oil before and it was in the clear, but I think someone siphoned my oil because there was very little in there...

Gave her an oil change and it seems to have gone away or reduced greatly. Always check your oil
