70 Headlight Washer Check Valves

Re: 70 Headlight Washer Check Valves

Hmmmm.

I am really curious to see what Terry says.

I wish I had taken pictures. My 70 definitely had tape identical to the vaccuum connections. All the hoses were original. In fact, I reused the original red striped hoses.

Well here is another case where you guys have taught me something. I certainly appreciate Rich's wisdom. I too did not know about the black 1969 check valves.

And my initial guess about the tape was stone wrong. Enjoy the picture. Mark -- now you have seen one.

I apologize for taking so long to get to this.

Digital cameras are so cool!

Most excellent! A great data point. Now, any 69s out there...original....with tape?

Good PIC Terry.

Re: 70 Headlight Washer Check Valves

Tx everyone for the responses. I guess I'll be taping these valves. I believe the tape width should be 3/8 in.

Great photo now more information into memory what is going to get pushed out. Would not have expected the tape in this location learned something new that makes my day.

As a side note Terry did you notice the color on the head light warning switch is a deep red or maroon color not black as we see in the later service parts. Or is it caused by the flash.

Paul,

I learned something today about the car I have owned for over forty years, so it is a banner day all around for all of us. On the other hand I stuck the camera where the sun don't shine -- kind of like going for one of those tests, don't you know?

Yes I noticed that maroon color, and it surprised me. It showed up with my LED trouble light, but I thought it was just the LEDs, but there it is in the picture. I can't get to the passenger side headlamp, so I don't know what that side is like. I guess I have to quite looking at these unseemly places.

Something I have observed about the fiber tape up on top where it is easily seen. I see it on 1969 and some of 1970, but later 1970 production it goes away, never to return. I can not tell you about the washer check valve specifically because I haven't been to this area of the car in several, maybe even three, decades -- but I can tell you about the tape on the vacuum lines at the filter (right off the intake) and on the T fitting on the driver's side inner fender area. It is these vacuum tapes that go away during mid to later 1970 production, and I wouldn't be surprised that the tape on the headlamp washer check valves goes away as well. Of course the whole headlamp washer system went away in early 1971 production.

On my old Sept. 71 had some tape in a few areas at the filter like yours and also the check valve and if I remember correctly at the front headlight tee large white striped hose.

First photo is the passenger side and second is the drivers side. Car is VIN # 14803 - Early July build.

Re: 70 Headlight Washer Check Valves

Both Dave's and Paul's are later with fiber tape than I would have thought, but at least we are getting more data points for the OPs question about the washer check valve. It is beginning to look like they might have been taped all the way through to the end. We need more data points guys. Post those dark and dirty (well, dirty for me anyway) places.

Re: 70 Headlight Washer Check Valves

Terry my 1970 original owner built on July 18,1970 still has the original rubber hoses and white/black plastic valves. I just inspected all this and there is no evidence of any tape on any of the hoses that connect to the valves.

Jim,
Your Corvette is two weeks from the end of 1970 production. Thanks for the boost to "what I thought" about the fiber tape.

Re: 70 Headlight Washer Check Valves

If some data is being put together my June 6th 70 has the white black valve with the fiber tape, just like the pictures Dave posted and the head light warning switches are black.I tried to post pictures of the left and right side but had difficulty.

Terry never noticed that tape on the check valves for the headlight washers on my 71 and may have look right passed them but found the remains of the tape at the engine connections filter, check valve and at the front headlamp tee. I do not have photos on the computer of that and if I do would have to go through a few hundred negatives

Re: 70 Headlight Washer Check Valves

Hello All,

I'm curious about these check valves as I didn't see them in the '70 AIM. (Headlamp Washer System, Hoses, UPC 1, sheet D10) They show "tees" only" and again on UPC 12, A13 Headlamp Vac Hose Routing, only "tees" are shown. Furthermore, in the 4th edition of the '70-'72 TIM & JG it makes no mention of the check valves either. (Ref. pg # 39 - Headlamp Bezel, Doors and Nozzles)

Is this an item that is cuerrently not judged and will it be added to the updated TIM & JG?

[Terry M.]

Re: 70 Headlight Washer Check Valves

I would have to look in the AIM, but I suspect, especially given the fiber tape found on some cars, that these arrived at St Louis as part of a harness assembly and are thus not shown in the AIM.

They could be currently judged -- if the judge knows about them and wants to or has the time to go there. Remember the title of the work is a Judging Guide. That means that it is not a blue print, and your Corvette is unlikely to contain everything that is mentioned, and many Corvettes contain some things that are not mentioned. Thus the judges are not restrained by the contents of the guide.

Given all the excitement this thread has generated among the Regional and National early C3 judges I think you can count on them being mentioned in the next revision of the TIM&JG.
