Default Big problem!!! Distributor rotor spining!!!

Hello All,

Ok, I have a 1989 Corvette. So I replaced my spark plugs, plug wires, distributor cap, coil, rotor and ignition module tonight. I fire it up and notice that when I turn the key to the "on" position (Not cranking yet) I can hear the rotor spining around in the cap..... Is that normal? The stock rotor did not spin when the key was turned to "on". I made sure everything was hooked up right....

So I crank it and it fires up and it's running smooth, firing better than ever has, when I notice! White smoke shooting out of my exhaust pipes!!!!! Also, its idling high at 10,000rpm.

Is the rotor suposed to spin with the key in the on position? The new one looked just like the old one so I don't think it is the wrong rotor/ignition module?

Could the white smoke be from me needing to take the car for a ride to let it adjust itself, to what is the best timing its probably had in 10 years.

Pleaes help, I don't want to break anything by driving the car like this!!!!

No it can't spin without the engine running. You're probably hearing your fuel pump, which should run for about 2 seconds

10,000 RPM? That's way past red line.

A bit of white smoke at fire up is usually the valve stem seals. Was it
just a bit, or serious fogging for mosquitoes? And your tune up didn't
included Sea Foam, did it?

Rotor and shaft are gear driven by camshaft. I agree with Sweets:fuel pump. "White smoke is either steam or valve stem seal oil leakage. Are you reading your tach properly or is that 10,000 a typo? :o

This is not even possible. There is nothing "electric" inside your distributor to make the rotor turn. As already mentioned, it's gear driven and can only turn with the engine turning.

Ok, how high is it really idling? There is no way your engine would even survive at that rpm.

Good point about steam. Steam will dissipate very quickly and be gone. Smoke will drift
away and thin out as it spreads out, but not gone.
