This proves it: -16 braided hose through rocker

[SoCal70RSR]

For anyone considering oil lines through the rocker to a fender cooler or front bumper cooler, AN-16 size braided hose fits OK... Here are some pics.

Wow
You really should think about washing your car every now and then

By the way, thanks to Pelicanite Doug Weirenga for guiding me through the install. Here are some more pics:

So did you just cut holes and start pushing???

[hobieboy]

Very very nice !!!!

I have a question about size: is AN-16 more comparable to the factory 30mm connectors & lines?

I have a set made up with AN-12 and I'm running into high temp issue Been wondering if its really a size issue since many of the internal passage on the engine are smaller than -12 I think? (Sorry for the hijack)

Yeap... I used this thread from Matt (Cali74) to guide me through the cutting. Once the holes are cut, insert one hose through the front wheel well and pull it out the back. The second hose is a little tighter, but it'll come out with a bit of pushing.

hobiejoy,

I originally had bought -12 hoses because I figured they would fit fine through the rocker, but then, I found some info here that basically boiled down to this "-12 is OK and should work find on the street, but -16 would be better" Not my words... just pharaphrasing what info I found in the archives. As far as I know, AN-16 is closer in size to the original plumbing.

Very nice use of the seat belt mount for the thermostat!

I will be venturing down this road soon. Can you tell me how much hose it took?

[SoCal70RSR]

Good catch on the seat belt mount bolt

I have to make one more hose, the one from the thermostat to the oil tank. Since my tub is a '70, it doesn't have the indentation to run the hoses parallel, so I have to run them over the wheel well. To make matters worse, I'll be running wide wheels 17X11 so I'm considering running the oil tank hose over the oil tank and around with a 180 connector (plan to do this one tonight). So to answer your question, I bought 36 feet of hose, I should have about 4 - 6 feet left when I'm done... better to be long then short...

Looks nice! I'm just a little concerned about the hole @ the bottom of picture 3. There is no grommet and this looks like it might be a wear point.

If others know this will not be a problem, please chime in.

[SoCal70RSR]

Sorry, I should've mentioned earlier... I'm not completely done with the installation. I plan to use some wrapping tape, rubber, grommets and possibly some foam to seal up the holes.

I don't think I'd use foam, it tends to hold moisture a long time when it gets wet.

[SoCal70RSR]

Hmmm.... I was thinking of using the "expanding" foam type you shoot from a can. Is the moisture issue for this type of foam as well?

[MattAlpha]

After the foam cures you will need to seal it to keep the moisture out. Once sealed it should work great.

Great work and thank you for the pictures,
Matt

Yeah, I think there are moisture issues with that stuff. I suppose you could try to seal it somehow, but it doesn't seem worth the effort, and if water gets past the sealant it would probably be trapped even longer.

I think a lot of people view using expanding foam on a car as a bit ghetto, I agree. I personally wouldn't use it if I owned your beauty!

[SoCal70RSR]

Thank you both for the tip on the foam...

The expanding foam is appealing because you can center the hoses where you want them and let the foam cure. Then add a layer of something else ?? to prevent moisture. If anyone else can think of a good way to seal these openings, I'm all ears.

[Slider79SC]

How about one of those replacement CV type boots that you could put around the oil lines and then glue the halves together? Then you could seal the end with RTV under the mounting lip and then screw it to the chassis?

I really like your set up. Does that thermostat have a built in pressure relief? I was thinking of using the same one in the future.

Grady was adament about needing a pressure relief, in this thread about front oil coolers: Additional Oil Cooler 1975 2.7

[SoCal70RSR]

The thermostat doesn't have a pressure relief valve.

It may very well be a problem down the road... not really sure. I've seen others use this type of thermostat and have not heard of a problem. I bought the thermostat from Patrick Motorsports and there was no mention of a pressure issue, not that he "had" to tell me either... what he did say is that they run this thermostat on many of their cars.

You could use some neoprene to seal the holes, either in a similar manner to the black trim you have added now, or around each oil line. You can buy neoprene pipe insulation at your local home improvement store. It will not absorb or hold moisture, and the flexibility will be a great asset for a good seal as the lines creep a bit under oil flow and temp changes. For example, you could slide some neoprene insulation around each tube where it enters the rocker and secure with a hose clamp or zip ties on the outside. From my experience, the expandable spray foam isn't durable in this type of application.
