I **think** the pinion bearing will make a sound like a marble swirling around in a coffee can. If it makes the noise when the clutch is engaged (pedal NOT depressed) it may be the throwout bearing.

Thank you,

Will do. Unfortunately, I got it into the shop too late to avoid the spring rush, so it is in wait mode. Given the weather here, that may not be a bad thing (rain and cold).

The good news, Gubi was correct.
I took my spider to Pinarello Motori and the conclusion, based on a test drive, was the boots were installed incorrectly and the awful sounds I was hearing were normal.
As expected, there were some other issues, such as the idle was too high (I knew that but didn't want anyone except an Alfa expert to fiddle with the spica) and he said it felt like an engine or transmission mount was deteriorating.
They will do a full inspection but I don't think much else is wrong, but the peace of mind is always nice.
Thanks to all who replied.

60sRacer Funny thing. I've had my 67 Duetto since new. Every time I took it to an Alfa dealer or Alfa specialist, I'd be told that the engine mounts need to be replaced.......

Kim Boydell Thanks Gubi
My mechanic commented on installing all the boots and seals, but let's hope he didn't get them on correctly, otherwise there are bigger problems.

BTW anyone else have to login twice, once when first accessing the BB and a second time when wanting to post? Not a big deal, but curious.

Gubi Here's a few photos I stole. There is a smaller inner boot that seals the shaft to the top of the tower (this keeps oil from leaking out of the tower down the transmission.) Then there is a second, bigger boot that seals between the shaft and the black metal ring on the body.

On some cars these are separate boots, on others it's a single piece that combines the two.

If these are missing or torn you will get a TON of transmission noise in the cabin even with a good transmission. They are generally installed after the transmission is in the car.

Thanks for this. As I mentioned earlier, I am no mechanic (oil changes, changing light bulbs, changing flats, basic screw turning is as far as I usually go.) I will still go to a knowledgeable mechanic.

I've done the job on my '63 and '74 which aren't too bad. The '91 would be a %&*$, and I suspect yours is somewhere in the middle.
Thanks Gubi
Well, it looks like the gearbox will be coming out again. Anyone know of a good Alfa mechanic in the Hamilton Burlington area of Ontario? I know of Pinarello Mortori in Toronto, but they are difficult to get to (more so for my wife who would have to pick me up once I dropped off the car).
