So, I have a generic sandwich plate adapter that I'm going to be using for my oil cooler setup. I'm planning on drilling and tapping that and installing my oil pressure sensor and oil pressure switch into the sandwich plate. My question is, does it matter which surface I drill out? Obviously, the tapped sections are going to be on the outer surface of the plate. What I'm concerned with, is which surface is the in/out on the adapter plate? Does the oil flow from the center of the filter, through the filter, return through the outer holes? Or the reverse? (returning through the center of the plate?

Oil is routed through the center and returns from the outer regions of the filter.

I would follow mocal or hyden's 20mm designs. Both have their thermostatic switches built into the plate. IMO figuring that out is the hard part. Pressure sensor is a matter of tapping into the right area of the plate housing or just keep it simple and mount elsewhere in your loop.

Good luck.

 

Nope. It's the other way around. Oil exits the filter from the middle. You can see, if you look hard, arrows cast into this mount, http://static.summitracing.com/globa...prm-1701_w.jpg, that show the direction of flow.

Also, there's an anti-drain back valve on the filter which is usually a ring of rubber just inside the filter. You can see it through the ring of holes around the middle hole. If you poke it with a screwdriver it moves easily. It's obviously a clear shot out of the filter from the center hole.

If you do route your oil flow backwards, you will starve the engine of oil and probably hurt it.

Don't forget the thermostat on your oil cooler.

That picture has the oil flowing IN the center (from the engine) and returning on the outer edge.

 

I can see how this can be mis-interpreted. From the filter/plate perspective, oil is routed through center and returns from outside.

 

The picture I showed is a remote filter mount. A filter screws onto it. Hoses run from the engine to the mount. The arrows show the direction of oil flow.

Picture #1 (http://i157.photobucket.com/albums/t...3/Misc/001.jpg) shows the side that touches the engine, since it has a gasket on it. Oil flows out the bottom fitting.

In picture #2, the oil comes out of the small hole off to the side, enters the filter, gets filtered as it turns 180deg, then returns to the engine through the large center hole.

Gotcha. I wasn't paying much attention, so it looked like that adapter plate mounted to the engine. Haha. My bad. I overlooked that.

Thanks!
