Hard to say. However, if the "rubber gasket" you're talking about is the center bushing on your harmonic balancer, that could throw your Harmonic balancer out of balance. This could easily make it shake to beat the band which in turn could be the knocking noise you're hearing. I suggest you get it looked at immediatly. If that is what happened, your engine won't survive long.
The harmonic balancer does require a puller if that is what you are asking.The harmonic balancer does require a puller if that is what you are asking.
If you jacked the car up from the harmonic balancer you could have bent the crankshaft or bent the harmonic balancer and now it is no longer balanced. Hope this helps
The oil leak is probably comming from the top of the oil pan there is a rubber gasket that goes between the oil pan and the water pumb which would make it look like its comming from the harmonic balancer, try replacing the oil pan gasket this should fix the problem. New answer: There is a small round oil seal / Harmonic balancer seal that fits in the timing cover and the balancer slides through the center of it. That is probley were your oil leak is. Most of the time the balancer itself gets a groove wore in it over time from that rubber seal running on it. You can repair the balancer by buying a Harmonic balancer repair sleeve/ speedy seal. Also replace the front timing cover seal.
If the oil is leaking from the timing chain cover behind the Harmonic Balancer (main large double pulley the belts run on). After removing the belts you need to remove the Harmonic Balancer using a puller, not to damage it, and then replace the seal in the cover. Inspect the back side of the Harmonic Balancer. The seal only seals to the shoulder of the Harmonic Balancer not the back face. If the shoulder's surface is not smooth replace it or it will leak again. Apply some light grease on the seal and mating surface of the Harmonic Balancer and reinstall. Re-install the belts. If it is leaking around the edges of the cover the sealant may need replacing. Also check the condition of the sealant around the oil pan. Both would require removal/cleaning and re-sealing.
since you didnt include any info on the car cant give a decent answer. look at the pulley on the bottom middle of your engine. thatll have to be removed along with the harmonic balancer then all you gotta do is remove all the bolts on the cover and remove it. throw a NEW gasket and some sealer on the new cover and torque it back down.

If its a legitimate knocking then you would want to go with head gasket if its a tapping you would be looking at a valve
Replace gasket why does gasket keep sliding
take off the head, replace gasket. reinstall head
replace head gasket
what caused knocking sounds for me was a pully on the serpentine belt that was attached to the power steering pump. the pump gasket busted which in turned damaged the pully. If you have a lift it is not too hard to replace. Doing while you're vehicle is on stands is a nightmare. its about a 650 fix at a mechanic...
What is the cost to replace the head gasket on a Mazda MPV?
