More Rear Mount Oil Cooler Questions, Setrab Setup Options

[BeatNavy]

I'm trying to nail down why I'm having oil cooler issues. Specifically, I've blown two sandwich plate adapter seals in the same place / manner. In addition, during my test drives I wasn't necessarily thrilled with the temp drop I was seeing.

First, I'm running the Setrab oil cooler and Setrab sandwich plate adapter. Anyone else running the Setrab sandwich plate adapter without any issues? I know I'm not the ONLY one, but how many people run this as opposed to something like the Mocal setup?

Second, when I contacted Pegasus Racing to order more seals, I spoke to the tech guy who gave me some food for thought. The most interesting thing was he said the oil cooler needs to be mounted with the inlet and outlet ports facing up, otherwise the cooler won't fill up all the way and you won't get ideal (or any) cooling.

Here's my setup with it angled somewhat down for what I hoped was good airflow: http://www.914world.com/bbs2/index.php?s=&...t&p=2826235

Essentially he says the oil takes "the path of least resistance" which could largely be from the inlet port to the outlet port using few of the cooling rows. I assumed the pressure would fill the cooler, but I can see what he's saying. Any thoughts on that? If that's the case, I really need to completely redo my mounting setup and plumbing.

Glad to read you solved the oil leaks.
Would you mind showing your hose routing? I see you are not in front of the valve covers. I have them there and it makes an issue when adjusting the valves.I would like to see yours before I do any cutting in the sheet metal

Hey Mark, hopefully I've solved the oil leaks. At least the major one at the sandwich plate adapter. Did second test drive this afternoon, and so far, so good. It may be as Rod ( @root ) told me several years ago with regard to 914's: "Three times. THREE TIMES! I have to do everything THREE TIMES before I get it right!" (IMG:style_emoticons/default/smile.gif)

I'll post pics of the hose routing once I put it back on the lift for inspection, but basically they go from the sandwich plate, up through the J-tube hole in the shelf tin, then back through holes I cut in the back tin (and grommeted) to the oil cooler. I also didn't want anything messing up access to the valves, and more than one person here suggested it, including Joe ( @Porschef ).

Oh I see what you did. But going through the J-tube hole kills half of the heat from the heat exchangers. I am not sure I can live with that. I would like to see your setup just the same.
I know what you mean about the "three's". Happens to me also

Some cars only had the aux blower going into the drivers side anyways. My '73 was set up this way.

Originally I added the aux fan splitter and the extra hose to the passenger side. When I installed the oil cooler I eliminated the pass side hose. The car got plenty hot inside without it. And I thought it just cluttered up the engine compartment even more.

The engine fan shroud is always sending air down the HEs whether it is directed into the pass compartment or dumped out under the car. So you really don't loose heat to that side. its just not boosted by the aux fan.
