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.

Hey guys, thanks for the interest and input. We had a brief but really intense thunderstorm not long after I posted on Monday evening, and we lost a HUGE branch off our "prized" tree out front. Plus a few Bradford Pears doing what Bradford Pears do. The last two and a half days has been cutting, limbing, loading, and hauling wood. Still not done, but I need to wait for my neighbor with his front loader. I'm absolutely beat from all that "fun."

Anyway, I took it out a few minutes ago. I got it up to temp, and it seemed to peak at around 210 (it's pretty hot out today, too). If that's where I peak, I'm ok with that. Best part is it didn't seem to leak -- I didn't leave a trail of Brad Penn 20W50 on our rural road like I did last week. I still need to take it out some more, as when I've had problems with that seal it's been on the 2nd or 3rd drive. I wonder if it had something to do with the air I was trapping in the system (IMG:style_emoticons/default/confused24.gif)

I kept pulling over to the side of the road and/or turn offs to peak under the car for massive leaks, and at one point to add a bunch more oil that had been pumped into the cooler. As one car was driving by fast in the traffic I heard a guy yell out "NINE FOURTEEN!!!" (IMG:style_emoticons/default/smile.gif)

I do have another issue to address sooner or later -- oil leak at the bottom of the oil pump cover plate. I'm guessing the front seal has given away partly, or perhaps the oil pump cover itself is leaking. Not cool, and either way I'm looking at an engine drop.

Rob, Thanks for posting your oil cooler installation threads. Good info for those of us considering an oil cooler.

Your comment above made me wonder how much additional oil you needed above the usual 4 quarts.

Another question. Does the additional oil drain back into the engine sump when the engine is shut off? Or does the oil in the cooler remain trapped in the cooler?

Thanks.
