Money shift., Help me figure this out. Options

[ottox914]

A friend of mine, whom I would trust with my life or my wife, was taking the 914 for a little test beating with me the other day. At about 7k rpm and 15 psi he money shifted me from 3rd to 2nd. He WAS very quick to throw the clutch back in, but...

I now need a new fan belt, as the OEM one was thrown and is slightly mangled at present. More concerning, is the noise it makes now. It isn't the 1 in 4 cycle "thump, thump" of a rod bearing. I can pull plug wires and rev it up and the sound remains. Its more of a tic-tic-tic-tic-tic thing. Due to the speed of the tic tic tic and that it goes up and down with rpm, I'm thinking valves. Not that i really want to think that.

Any other thoughts or trouble shooting to be tried that anyone else can think of?

I'm thinking to start with compression test, move to leakdown, and submit some of the oil for testing of metallic ick. I can do the compression test and send in the oil, but I don't have the tools for the leakdow.

Wow! Sorry to here. Maybe it dropped a seat. Use a long screw driver up to your ear and touch the engine around each cylinder. Maybe you can locate the cylinder and start there.

Tried that from the top side, but my screwdriver wasn't quite long enough. I know, that sounds more like a personal problem, but it is what it is... are you thinking from the under the car, where I can get at the actual motor, and not just the tin? I would think the tin would to a degree "share" the tic-tic-tic between cylinders, so I might be able to narrow it down to one side sounding different from the other, but maybe not narrow it to a specific hole. I could always pull the valve covers and rotate the motor and watch the valve stems to see if one or more is that far out of whack.

I'd like to think we didn't do any MORE damage, we drove it back the 3-4 miles to my house at low speeds and low rpm's.

I didn't think our motors were interference. But I never thought about that when Jake, Len, and myself were spec'ing out the configuration of this motor.
