62 Starfire Fan, Fan Clutch and Air Cleaner?

In the process of restoring my 62 Starfire I discovered some possibly incorrect parts. My car does not have A/C but has a 7 blade fan vs. a 4 blade fan and it has thermostatic fan clutch. The chrome air cleaner cover has a fitting on the snout for a 5/8 dia. hose. I looks like it might be for a pcv valve, but there is no where to connect it. I have a chrome vent pipe running from the right valve cover down the side of the engine. The illustration of the 345 HP motor in my 62 Olds brochure shows a 4 blade fan and no fitting or pipe on the air cleaner. Any help is appreciated.

Well, I solved part of the mystery. I found two photos of a 63 Starfire engine, both showed the hose running from the air cleaner snout to the right valve cover with the pcv valve.

Oldsfan has a California-built '62 Starfire with original PCV & could probably clear this up.
Which I would be more than glad to take photos of it if wasn't in a hundred pieces.
Not California built, but it was a California car with PCV. Built in Lansing, which I still don't understand. Only thing I can figure is it was a Lansing factory delivery. It's a June built car. I have this grand fantasy that the original owner was a school teacher who took delivery at the factory and then drove it to Seattle for the World's Fair, for which Oldsmobile was the official car, and then home to California. Makes for a good story, doesn't it? Unfortunately, I have NO documentation.
Pre-'62 Non PCV cars used that downdraft tube. The PCV cars had a hose in place of that tube that ran to a valve in a spacer plate under the carb as Chuck mentioned. Post '62 cars had a valve mounted right at the valve cover grommet with a hose that ran up to that port on the snorkel.
And, A/C fans were 6 blade, not 7, at least in '62.

Thanks gentlemen, my car is also in many pieces. But, with the help of some photos I found on the web, here's what I think happened. My radiator is a Harrison 3 row whch is correct for a non A/C car. I think as the car aged and the radiator became clogged and less able to cool the engine, the 6 blade fan,(thanks Oldsfan)fan clutch and the fan blade surround were added. I noticed when I took the car apart that the fan surround was not fastened correctly to the car. I had the radiator completely rebuilt so I think I will keep the 6 blade fan and lose the fan clutch and fan surround. Or will the 6 blade fan be too noisy without the fan clutch? What do you think?

I've had no personal experience with this, but it's my understanding that clutch fans aren't supposed to be operated at engine speed. For one thing, they can be quite noisy. The more important thing to consider is safety. Those old clutch fans weren't designed to operate at a high RPMs. If one of those blades let go it could play havoc with your engine compartment, your hood, or your head!
Non-AC fans on these cars consisted of two heavy steel blades riveted together in an X fashion to make a 4-bladed fan. Then the whole assembly is bolted to the water pump. Barring some unfathomable catastrophe, there's almost no way one of those fans could come apart.
You mentioned that you had a fan surround. Are you referring to the ring that goes around the fan? This is also an AC-only part which you really wouldn't need in a non-AC car with a standard fan. Because of the lack of the fan ring, non-AC cars also have a larger guard at the top of the radiator.
If you're not particular about keeping the car correct, you'll probably be fine with the existing clutch fan & ring. If you want to take it back to stock, it wouldn't be terribly difficult to find a standard fan, pulley & a guard. Paul, do you still have that stuff off the parts car?
Before you go buying parts, I'd suggest confirming that you have a '62 engine. Your '63-4 air cleaner is a minor red flag. I've seen a few '61 & '62 cars with '63-4 engines in them. These particular motors have different front covers & water pumps & thus MAY have different fans, shrouds, etc.
'61 & '62 394 motors have a front cover with a small round water pump face & a lower hose connection that points straight down. '63-4 motors have a large rectangular water pump with a lower hose that points off to the driver's side at about a 45-degree angle.
Here's a link to a lengthy Starfire thread with some illustrations of the differences between the front covers:

To determine if you have a Starfire engine, look at the boss on the cylinder head between the middle two pistons. It will likely be on the driver's side of the engine. 1962 Starfire engine numbers have a "G" prefix, then start with 300001, & are followed by an "S" suffix.

The plot thickens. The fan clutch on my car is not attached to the fan blade it bolts thru the fan into the water pump, so I could install just the fan. I took the following numbers off the left head today, G 586745 S. According to my shop manual the G and S are correct for a Starfire, but as you stated the number should start with a 3. I'm pretty sure the number started with 5 not 3. I will confirm tomorrow. When I figure out how to, I will post a picture of the front of my engine. The water pump is round and the water outlet points straight down.

Gentlemen, these parts have been off the car for a long time, but you are correct, I also have a big hole in my fan that connects to the back of fan clutch and the clutch attaches to the water pump. I cannot put this fan on the car without the clutch. I'm pretty sure that the fan guard I have is correct. How can I post a photo to a post? I OK with you I could email you a photo to you're email address.
Mine is tpawlik@ocincnet.com
Thanks again,
Tom

There was a heavy duty cooling option available on these cars according to an invoice of one I looked at from someone on ebay selling theirs. But it came with a 4 row radiator. Check your top bracket to see if the radiator fits tight into it. The clutch fans are all made that way, even today.
