Side by Side Photo L/M PCV Tubes
Posted by: Phil Dally ()
Date: February 20, 2020 04:12PM

After recent oil bath purchase I needed to find the right PCV tube.

From left to right: 140, 110/95, and oil bath for all three.

The new question is are the smog PCV tubes different?

Thanks to Jeff W at CA Corvair for clarification.

Try finding one for the Desert Air option package. Same with the "J" bolts.

Here is a picture of the PVC tube for option K46 installed and with the the air cleaner removed.

The assembly manual shows this set-up on a two carb engine (95hp and 110hp) and I have never seen option K47 on a 140hp, but the assembly manual does not specifically say it is not available on a 140hp.

Anyone know how to definitively tell if K47 was not available with a 140hp?

The breather tube for the smog engines attaches to the cross over tube of the air cleaner and is the same for 2 carb and 4 carb. It looks a lot like the tube that is used with the PCV valve system. The easy way to tell a smog tube from the PCV tube is that the smog has the small orifice on the short leg of the tube and the PCV doesn't. The leg of the PCV tube is open because the valve does the metering that the orifice would do on the other systems.

The PCV tube for the '68-9 smog system goes into the air crossover, and NOT into the air cleaner can. Attached is a picture of this as installed on a '66-7 a/c car (recommended in order to prevent bashed up condenser cores.)

Thank You Mark!!! Same for 1966 California only smog application?

If you're reading this Jeff I want both a K47 and a smog tube.

Wasn't there another oddball air cleaner besides Desert Air?

Also Harry's question about 140 Desert Air remains open.

We have not addressed the Corsa 180 turbo vent tubes.

Harry,
From Dave Newell's book THE (in)COMPLEAT CORVAIR STORY, page 57: "With the relocation of the condenser, the special setup for A/C was not used in '66. All other engine options remained as they were in '65 including the 140 which used a single-snorkel air cleaner when equipped with K47.".

Did the 1965 A/C cars which used Early Model air cleaners also use an E/M style PCV fitting?

Yes Phil. 65 A/C cars used a PCV valve instead of a metered orifice. I am not sure about the rare rare 65 A/C cars that had
the oil bath air cleaner option though. I believe all the turbo Corvairs used the same chrome PCV tube except the engines
that had a road draft tube.

Harry,
I went looking for additional confirmation regarding K47 availability with the 140, but found conflicting info. These two pages come from the Fingertip Facts Book, intended only for Chevrolet personnel (salesmen). According to this catalog's pages, the K46 was available on the 140, although the K47 is not mentioned. Oil bath is listed for 95, 110, and 180, but not 140. Haven't ever seen desert air on 140. Dave Newell has shown me many kindnesses and considerations in the past, I'd more likely believe him than a GM pub. We know those situations were often changed after printing.

I've found that you sometimes have to take GM publications with a grain of salt. Most of the time they're the most accurate that can be had. but on occasion can be in error or even contradict other GM literature. It often is the product of who develops the literature, the marketing people or the engineering department. For accuracy's sake, believe literature that the engineers developed rather than the marketing people.

I may have that smog tube in my stash along with the smog air tube for the carbs. Came from a 68 I scrapped. I will have to look at the PCV pipes I have. One seemed shorter than the rest.
