70 L46 TCS Wire Clip on Valve Cover and..

[Bill L.]

There is a 70 L46 Convertible for sale right now on ebay.

It looks to b every original. 39,000 miles.

The one picture shows nylon tape on the one way valve on the vacuum line out the back of the carb. It also shows a clip on the passenger side valve cover to hold the TCS wiring going to the solenoid mounted on the intake.

Is this correct? I checked my AIM and no clip is called out. I also do not recall the nylon tape.

Thanks,



Bill

Bill my 1970 original owner 350/300 turbo 400's passenger side valve cover has the clip installed on the valve cover. I replaced the original QJet with a Holley 6210 spread bore double pumper 650 in 1974. I do not remember a vacuum line coming from the back of the carb. I still have the original QJet in storage. I will look at it if you need me to. There is a vacuum connection distributon valve behind the carburator location screwed into the intake manifold that has a connection for the power brake vacuum and vacuum connection for vacuum supply line going to the vacuum storage tank mounted to the left of the master brake cylinder

Very interesting Jim. Thank you.

I have the valve exactly as shown in the picture. I am curious about the nylon tape wrapped around the valve and hose.

The AIM does not shown that clip, yet yours has the clip and so does the 39,000 mile example.

Hmmm.

Not sure this is the clip you are talking about. It is a clip that was on
the 70 LT-1 Camaro Z28. I put a picture of it for reference.

Re: 70 L46 TCS Wire Clip on Valve Cover and..

That is exactly the clip.

Wonder if the clip is the same as used for the plug wires by the oil pan?

Thanks,

Clip is different. The oil pan clip has a step built in to clear the oil pan side rail, also the shape of the clip is different.

I'm going to say the taped valve is from the vacuum port on the rear of the manifold, not the rear of the carb. Looks as it should to me as far as the tape. Don't recall seeing a clip on the L-46 valve cover. Not on mine

Re: 70 L46 TCS Wire Clip on Valve Cover and..

Great pics Dennis.

What is the serial number on your L46? The 39,000 mile original has the early shielding like yours and the clip on the valve cover.

I do not see the tape on your valve.

I also noticed that the bolt holding the coil bracket is painted orange.

These pics are worth a thousands words

I am guessing the clip is not a requirement as far as the judges are concerned?

Re: 70 L46 TCS Wire Clip on Valve Cover and..

There is a 1969 here at the Sacramento meet with the tape on the vacuum filter, and unlike that picture this tape looks original. A 1970 would have that clip on the rocker cover bolt for the TCS wires. I know we discussed that clip on this borad. There is a manufacturer's logo on it. I remember taking a picture of it some time back.

The orange bolt on the coil bracket is described in the TIM&JG. The TIM&JG will tell you why it is orange, and why the other coil bracket bolt is not orange. Don't guess -- read and follow the book.

The close up pic was to show the hose connection to the manifold. The bolts may have been mixed up. That's an old photo, before I refurbished. BTW I don't see the why as to the plate/paint thing with the bolts in the TIM/JG p65/66.

My Vin is 11327. Earlier than yours. The only two pieces of the original shielding were the supports when I took ownership. The supports were for the later style one piece shielding. Hmmm. I may have to try to seek out the early style shielding.

I don't get the bolts either inasmuch as the coil bracket was added after painting.

I also noticed that there is a spring clamp on the hose to the vacuum.

Like Terry said, I really need to read the TIM/JG more carefully.


Thanks again.

I was pretty sure the explaination was in the TIM&JG, and I have covered it here before as well.

One of the coil bracket screws (the one under the slotted side of the bracket) was installed at the engine plant and thus (on cast iron intake manifolds) got painted orange with the rest of the engine. At St Louis they installed the coil bracket under the existing screw and added the screw in the other hole in the bracket. This screw, since it was installed in St Louis, was silver color. The worker then tightened both screws and the car was on its way.

The clue to this is in the AIM on the page that shows the coil installation. The coil and the coil bracket arrived at St Louis as an assembly. There will be a box that is half white and half dark pointing to inboard coil mounting screw. That symbol means "installed by others" -- in this case the engine plant. This did not happen all the way from 1968-1972. You will have to check the AIM for your year to be sure of what the install practice was. This is just like the heater hose nipple into the water pump -- but that is an other story for another time -- and I have covered that one with respect to 1970-72 on this board before as well.

Terry,

All I can say is I am continually amazed at your knowledge

Thank you.

Re: 70 L46 TCS Wire Clip on Valve Cover and..

Good idea Dennis because this detail about the coil mounting bolts will be hard to find with the search engine because it is in a thread about 70 L46 TCS Wire Clip on Valve Cover and... We often veer off topic on this board to our long term detriment.

I will have some pictures to post on the original topic when I get home, express my fondness to my family, and have a few moments to catch my breath.
