Engine 2000 RPM Vibration

93CalypsoConvert · Oct 30, 2021

I've got a vibration between 2000-2400 RPMs that gets worse with clutch engaged. It does it in all gears going any speed, or revving. It gets worse with load too. Not quite sure what it could be. I can feel it the most when I rest my hand on the shifter. Balancer? Clutch plate? Trans input bearing/shaft?

There you go, carbed 5.0s don't like odd timing numbers.
do 12* or 14*

A Misfire then slipped balancer are where I’d start.

Ok so I replaced the balancer. It got better, but not fixed. I have a cylinder which isn’t running as hot as the others, however, the vibration is present even if I remove the plug wire. Any other ideas?

If the vibration does not get worse with the wire pulled on the cool cylinder, you have found the misfiring one.

I had the same issue with my car with a vibration around 3k.

Ended up being a dead injector.

Looks like you found your cylinder. Now to check spark, fuel and compression (and air but you are likely ok there)

I still cant figure out this vibration. Its firing on all cylinders, has a new balancer, and it still does it without the belt.

The only thing left would be the pressure plate and flywheel right? It vibrates under any condition, completely engine related.

Check your fan. I’ve had bearings go bad on the fan clutch (actually found ball bearings in the driveway) and caused some serious vibrations.

Is it the same cylinder with the lifter problem from your other thread?

Vibration still there without the belt installed.

Yes, but I think I'm chasing two different problems. The vibration is there on deceleration, so a misfire should be out of the question.

Should’ve read the posts instead of skimming through! My bad. Lol

Took my flywheel/clutch assembly apart. Figured out I have a Valeo clutch and pressure plate. I can't see anything wrong with it. Is my flywheel supposed to have locating pins in it? Mine does not. Doesn't look like the pressure plate even has holes for pins? Interesting. Is there anything concerning here?

General karthief · Jan 7, 2022

Yes, there should be pins on the flywheel.
I just bought a valeo clutch for my ride

Rdub6 · Jan 7, 2022

That’s what I got spinning on my ride

93CalypsoConvert · Jan 7, 2022

Does yours fit into the locating pins? Mine does not appear to be set up to use pins.

Rdub6 · Jan 7, 2022

I definitely had pins on my flywheel when I did my install.

93CalypsoConvert · Jan 7, 2022

Weird. Even with pins, they wouldn't be doing anything. Nothing lines up other than the six bolts.

Your Valeo part number says AMC 01. I'm used to seeing the Valeo part # FDC 09. The alignment pins being missing could be your issue. They are different sizes depending on brand of flywheel. You also need to take a picture of the back side of the flywheel. It could be the incorrect balance for your engine.

93CalypsoConvert · Jan 7, 2022

Interesting. I will run the engine with just the flywheel and see if the vibration is still there. Back of the flywheel appears to be 50oz. Weight is too large to be 28. I can post a picture tomorrow. Part #E1ZR if I remember correctly.
