Did 1967 console gauge cars also have a low oil pressure switch?  Was it located in the rear of the engine block (any pics)?  It was separate from the oil pressure line?    Where did the low oil pressure light come on when illuminated - dash cluster?  Thanks

 I don't think so. The gauge attachment point to the block is where the oil light pressure sensor would have been screwed into if you didn't order the gauge package.
I have two BB 67's and the one with the gauge option has the oil line screwed in the same block fitting that the 'idiot light' sensor is screwed into on the other car.
The AIM shows this in U17 / A4

I've never saw any  car with both units. Does your car have both? If so where are the senders located?

Nope. The oil pressure gauge line occupied that port next to the distributor on a car with gauges.

The OIL lamp in a car w/o gauges would be next to the BRAKE lamp in the speed-o.  There is a (low) FUEL lamp in cars with gauges instead of the OIL lamp.

Mike,
Just wondering, do your 67's have a brass fitting or a rubber grommet for the oil line at the firewall?

Hi Bob,

  It's a grommet. I do have a brass one that I pulled from a parts car back in '87 that was screwed thru the firewall and the oil line was 2 pieces. I heard here that was never factory fitting but I dispute it because I have heard other people with the same setup in earlier Camaros. The car I removed this from was Dec 66 SS350 if I remember right.

Thought that was standard on Chevelle and Impala lines in mid sixties, maybe dealership service replacements?

 Anyone with the brass fitting have pictures to post?
I'm looking for one I pulled from a car 25 years ago to take a picture of.
I'll post it when I find it so we can compare.

Mike,
Just trying to pin down the change over date to the rubber grommet. I have a 05E build and not sure what to use as the change over was some time in May or June. Grin

I found the fitting and attached 2 pictures showing the body and the oil line compression method.
I removed this from a Dec 66 Camaro w/gauges parts car in '82 (not 87 like I said before). Notice there is a nut in the middle of the fitting to snug it to the firewall.

My 67 5B NOR car has the grommet and a single oil line. Looking at U17/A3 & A4 I see "Redrawn & redesigned" 3-10-67 and just show the grommet so I wonder if they eliminated the brass fitting if it did exist

Hi Brian K. here, I took a quick measurement of the firewall to engine block line and it's about 7 inches long. I dont have access to my inside line but the Chevrolet service bullentin says that dealers are to take off the junction, drill the hole bigger (1/2 inch in size) use the line thats inside the car to go to the block (it supposed to be long enough) and add the rubber grommet part number 3906193. Remember this is for people bringing their cars back to the dealer with oil leaks, that how GM told the dealer to fix it. The bullentin says effective June 5, 1967 the 2 piece design will be replaced to this one piece set up in production cars. My 11E build 67 RSSS has this set up owned since 1988, my original lines are white translucet in color. The current repops are black, I've found a good replacement from Auto Meter part number 990023 which looks and functions like original. Glad to help, I'm using my dads account here sorry for any confusion. Sincerely Brian Kotula

The bulletin may have listed June 5th but that is likely for the cars with the brass fitting installed before the redesign mentioned as 3/10/67 in the AM. I would suspect after that date the oil line was a single unit and used a grommet and the service bulletin released afterwards when failures started to show in the field. The AM drawing release date showing only the grommet was 4-15-67. So I would say Bob that your 5E likely came with the oil line and grommet. What size is the hole in your firewall? That should give an idea of what you should be using.

Mike,
That is why I am questioning the 6-5-67 date because I have a .320+or - hole in my firewall 5E and your 5B has a grommet .500+or-.

Hi Bob,

   Now that is interesting in that it looks like the brass fitting was still used despite the design change around March 67 and the drawing date in April showing the grommet and your May car has the smaller hole indicating brass.
   I guess at this stage it would be good to see others chime in if their oil gauge uses a grommet or the firewall brass junction.
Lets start a separate thread to solicit input!?  Huh

Mike,
One thing to remember is that AIM revision dates do not correspond to line change. John Z I believe, stated that line change could have taken effect several months before or after an AIM revision.
The service bulletin states that June 5 would be the cut-off date for the 2 piece fitting on the production line, but I am not sure how that would have played out.
Could be that test runs where mad before cut-off for drilling the 1/2'' hole and installing the grommet as this was part of an RPO and not a Fisher Line piercing.
Maybe John Z could comment on the time frame?  Grin

The revision date in the AIM is the date when Engineering Graphics released the new sheet; the actual implementation date on the line was managed through the NPC (Notice of Production Change) system, and very few closed-out NPC's (with implementation dates and VINs) have ever been published. The best indicator is observation of known-original cars.

Bob,
 
  In regards to Brian K's comment earlier ".......My 11E build 67 RSSS has this set up owned since 1988, ....."   which setup is he referring to...brass of grommet?
Which plant was your Camaro made? I wonder now if mine had the retro done afterwards by the dealer.  Huh

I feel like the German peeking from behind the branches (Arte Johnson) from Rowan & Martins ...."veddy interesting"  Cheesy

Mike,
Interesting point but why didn't my NOR 05E ( I bought in 5-15-70 from King Car rental) have it done at the dealer. As a dealer modification I am not sure if the mod. ( no recall) was done on all new product or only if the customer complained of an oil leak.

Not sure what the rental cars went through back then. In 1967 I was in 6th grade! I'm thinking now that the previous owner had a leak so the mod was performed. That's the only thing that sounds logical at this point. I'd sure like to see more input to this from owners of 67's with the gauge option.

 Sorry, not on topic but, I was in 5th grade in '68 and the secretary for the grade school bought a brand new 68 Camaro.  I watched that thing over the years and her daughter still has it.

More info on the AIM and dates: http://www.camaros.org/AIM.shtml

Rental cars were prepped thru dealerships back then. I don't know when that changed, but I've seen ledgers of dealerships selling their cars to Hertz.

 Thanks Kurt…Interesting reading!
So, one certainty with mass production is uncertainty.  Roll Eyes
Would it be safe to assume then that in this case of when the brass fitting was discontinued in place of the grommet, that there would not be an overlap of use or would an overlap be possible to empty inventory? Bobs 5E car has the brass and my earlier 5B has the grommet. It’s sounding more like my car had the dealer mod done at some unknown point in time.

In both 67 norwood cars I have the brass fitting in both  03B 350/295 auto, 03C 396/325 auto.
In the 2 Los cars: 02C 396/325 auto rubber grommet, 05C 396/375 4 spd rubber grommet.
The pics below are of the norwood 03B nor 350/295 auto. Looks just like the one in the 03C 396/325 auto.
The pic with the rubber grommet is from the Los 02C 396/325 auto.
The 05C 396/375 4 spd Los car was missing the rubber grommet.

Photo of the firewall for the oil pressure line to the console gauge. It has a grommet but you can see the score mark in the paint wher the brass fitting used to be. It must have been repaired at one time and changed to the grommet. 11C 1968 build.

Is any one able to tell me if the line and fittings need two of the small barrel sleeves (one on each end)?  My block fitting came with only one of these sleeves. If only one is needed what side does it go on (block or gauge)?
