Maintenance / Re: rear differential fluid

« on: August 20, 2020, 02:07:13 PM »

Thanks to everyone who has responded to my post, I really appreciate the response.

When we jacked the car up to turn the wheels we found the original GM sticker on the rear end advising to add posi traction lubricant. Brilliant. We turned the wheels anyway and yes, it is a posi traction rear end.

Thanks for all the info on rear diff fluid and additive, I now have some on order, arriving shortly.

Best regards, Nigel

Hi Warren, To be honest I am not sure. Is there any markings on the rear end which will tell me one way or another. Many thanks Nigel

Maintenance / rear differential fluid

« on: August 14, 2020, 11:46:38 AM »

Hi there. My mechanic is going to change the rear diff gasket next week and I wanted to check what grade differential fluid was correct for my car. It is a 1968 RS / SS 350 L48 with it's original rear end.  If there is a particular brand then that would be good to know too. Also the quantity I need to purchase.

Many thanks in advance, Nigel

Restoration / correct air cleaner to valve cover hose 1968 L48 engine & standard air cleaner

« on: April 28, 2020, 02:40:03 PM »

Dear Sirs, I am trying to locate the correct hose which runs from the right valve cover to the back of the air cleaner. I have a 1968 Camaro RS/SS with L48 350, 295 hp engine and original single snorkel air cleaner.

Please can you advise the correct GM part number and also where I may be able to purchase one.

Many thanks as always,, Nigel

Thank you again Ed for clarifying the part number, I really appreciate it. I will go ahead now and order the PCV.

Is there anywhere that I can download a copy of the 1967 - 1968 Camaro Parts and Accessories manual or is it something you can only buy as a physical book. I think it would really be useful to me in the future.

Kind regards, Nigel

Thanks Ed,

To clarify, the left hand side (drivers side) valve cover has the Edelbrock vent and the right hand side (passenger side) PCV valve hose runs to my carburetor currently.

I understand that the passenger side hose should run to the air cleaner and the drivers side hose should run to the carburetor.

There is currently a rubber stopper in the back of the air cleaner. If I remove the stopper I presume I need to purchase the correct connector to go into the back of the air cleaner. The hose will then attach to this connector.

Thank you for confirming the correct PCV valve for my engine, I really appreciate it. Unfortunately I am in the UK so no Rock Auto but I will track one down.

Kind regards, Nigel

Hi Ed, Just to clarify as well I did mean PCV valve.

I checked this morning and the left hand side valve cover PCV valve hose runs to my carburetor and the right hand side valve cover has the Edelbrock vent.

I had a look online and it appears that the correct PCV Valve for the L48 350 SS (with correct Rochester 4 barrel carb) is GM part no 6421972 (CV679C) however I would be grateful if you can confirm this before I go ahead and purchase one.

I also checked the air cleaner which has a rubber bung in the back. Is there a special fitting which goes into the air cleaner or does the hose just attach directly to the air cleaner once the bung has been removed?

Many thanks in advance, Nigel
