Pillar Emblem

Recommended Posts

In looking at jmarks fantastic shots of his newly painted Z, I'm reminded of a comment that was made in reference to the 240Z. The area were the pillar emblem is located, there should be a hole to allow for air flow within the cabin of the car. Is this hole very small or is it suppose to be quite visable.

Scott's Z has a red LED light that glows from behind both pillar emblems. I don't recall seeing a hole on the 280Z.

Hey Vicky, The first Z's that had the "240Z" pillar emblem probably had no hole as those cars vented out the hatch vents. Then the cars with the round Z emblem have holes about the size of a golf ball. All later 240/260/280Z's will have the vent hole behind the round emblem.

Hi Chris

Yes both cars have a golf ball size hole but it doesn't appear to allow air in the cabin, unless there tiny holes further back within the golf ball sized hole.

I always thought this was just a visual, rather than a functional item on our cars.

It can pretty much be said that all cars with the round pillar emblems have vent holes as ya'll are discussing. The exception applies to 432s and prototype models. The hole is for venting purposes and was originally back painted black.

This has been discussed many times before, and is one of the differences between series 1 and series 2 240z's. Series 1 dont have a hole behind the emblem (they had the 240z emblem the vents were in the hatch). Series 2 had the round emblem and a vent hole behind it. (moved possibly due to exhaust fumes getting in through the hatch vents).

Behind the hole is a pressed metal plate which is open at the top a few inches above the hole, so the rain and weather doesn't get it.

P.S. my 240z has one of each. A hole on one side and no hole on the other where the entire panel was replaced with a series 1 panel after an accident

There's a formed sheet metal piece in there that blocks the view from outside the car as to where the air enters from inside the car. Jeez that sounded confusing.

Mr Camo beat me to it.!!

Here is a picture from the inside. You can see the opening at the top.

Also if you look the emblem is sided so that it will vent while in motion. They are imprented on the back side R L and the slits are positiond to the rear. I think mostly that they were vents to allow the interior pressure to escape when the doors closed , if the windows and other fresh air vents were shut. I dont think that they really will clear much of the cabin air.

Flow-thru ventilation was one of Datsun's big selling points at the time. Considering the 240Z was one of the first automobiles equipped with such a feature, it is not unreasonable to understand that it didn't work as well as ventilation systems work today. The early cars with the hatch vents established ventilation through an elaborate system of ducts and louvers incorporating a rubber flap as a backdraft preventer. By comparison, the pillar vents are much more sophisticated. Still, it is unfair to compair their performance to anything contemporary.

Are these hole's supposed to be black?

Ed,

As you know, I am not a pillar vent kind of guy. I am a hatch venter. But I understand from my most respected gurus that the hole is supposed to be black. I was standing around some time ago listening to a guy go on and on about how his car was original paint and the snide comment was made based on the fact that his vent holes were not black. Beandip is also correct about the right and left hand applications of the emblem. I know its picky, but I wanted to share it with you guys.

Have a look at almost any car from that period. Most have holes or some kind of "vent" for this purpose.

FYI, The C110 has one vent, on the right behind the badge (the left is a petrol cap)

Hi Ed, Chris (26th) is right on. The 72 I used to have was brown but that inner panel in the hole was black. My 73 was repainted and it too was black inside.

Ed,

When I got new emblems from Chloe a while back I noticed that one was marked L and the other R. I installed them that way but otherwise didn't see any difference between them. I suppose I'll have to pull them back off and inspect them more carefully.

It can pretty much be said that all cars with the round pillar emblems have vent holes as ya'll are discussing. The exception applies to 432s and prototype models.

Clarification: Not JUST the 432s, but ALL the Japanese home market models had a round pillar emblem with the 'Z' mark in the centre. This emblem is often mistaken for a 'vent' type emblem, when in fact it is solid, and mounts on the two small holes in the quarter panel.

Home market cars switched over to the same 'vent' style emblem at the same time as the Export cars.

Pic of earliest home market pillar emblem for reference ( notice its round, solid, and not vented ):

They were indeed painted black ( pretty much flat black ) and by the same guy, with the same brush and pot of paint, as other areas of the car. Notably the metal behind some of the plastic trim gaps, and the front of the rad support panel.

Mr Ishikawa ( who was left-handed ) worked alternate weeks to Mr Imura ( who was right-handed ). Do you have left-handed or right-handed brush strokes? :bunny:

I can confirm that on my '78 there is an opening at the top of both pillar emblems. Checked it on my car tonight. Learn something new every day.....

On my '73, the vents look like they go nowhere. Was Nissan going to put something there later? I also have the emblem with the "Z", but it is not solid. (has 4 cutouts, one top, 2 side and one bottom.) What is the real "Original" one?

The vents actually open towards the top. What you have sounds original.

Ha! I didn't realize that! Send me to my photographs! Sure enough, here is a picture of an S30 with round emblems and hatch vents. The PS30 shows the same, but my pictures of an S30-S do not include hatch vents. Of course that makes sense. The home market cars would not have 240Z on the pillar, would they?

You must be insinuating that the North American imports were left-strokers and the home market cars were right-strokers?
