914 flywheel noise? Options

[Socal70]

So I just pulled my transmission out of my 70 (side shifter with a 1.8), I replaced my flywheel due to work teeth, got the car back together and the car sounded great for 5 minutes and then developed a light grinding noise. It's coming from the transmission area and most noticeable when it's idling. Anyone had similar issues?

Yes Anytime you replace a part (case, crank, bearing, or flywheel) the end play needs to be rechecked. the pocket in the flywheel determines the amount of shim required. the face inside the pocket seats on the crank and the face on the outer edge sets the amount of shim required. The "o" ring stops oil from leaving the bearing or shim pack and going past the bolt threads onto the clutch. It set in the grove between the two faces. Back the clutch cable off and wedge the throw out bearing away from the clutch then start the engine. That will insure that the noise is not the bearing. next reset the cable, start the engine, push in the clutch, listen for a change in noise, with the clutch pushed down put the transmission in and out of gear, notice any change in noise- pilot bearing.
