Bad noise in my 67.

[en-gedi]

OK…… Here is my issue.
I just purchased a 1967 Toro from California. The body and the interior are immaculate. Mechanically however there are some issues. I knew this before I purchased the car and it was priced accordingly. But I am uncertain how to proceed.
The car turns over and runs. It makes a rather disturbing noise however that only increases with higher RPMs. I can only describe the noise as an abrupt squeaking (metal on metal maybe) that actually shakes the car a bit. No it is not a fan belt. Far too ugly and violent for that.
Could it be that the bolts between the flywheel and the torque convertor have come loose? I heard this can happen.
Any Ideas?
If I need to re do the motor is “remanufactured” a good route to go?
Thanks

With any luck, it's the water pump. Check it for wobble and weeping. Take belts off and spin it to see if it makes noise. Otherwise, try and determine better where the noise is from and isolate. Use the old screwdriver to your ear method if you have to. If it's internal.....it sounds like a bearing, probably the mains.

You can take ALL the belts off and run the car for a minute or so and see if you still have the sound. This will definitely isolate the water pump, AC compressor, and alternator. If you still have noise, it's the engine.

In that case, it's rebuild time. ): Need more info as to whether you have your original engine rebuilt or buy one rebuilt. In either case, the engine shop MUST know the Olds 425 intimately and have done Olds before, as they ain't no Chevy 350 crate motor!
