Greetings RV'ers,
On the RV-8, I've got Stewart/Warner 10610R 10 row oil cooler for the IO-390. It's mounted on the rear baffle and its worked well and kept the oil temps in the low 180's under all conditions.
I noticed today, that the outside mounting flange that goes next to the baffle is cracked. I suppose I could get it welded or brazed or whatever they do to aluminium, but that seems like a hack.
Apparently, Chief doesn't carry the Stewart/Warner brand anymore and has to different variants of the Aero Classic brand in the 10 Row 10610R compatible unit.
One is the "Standard" model for $269:

The other is the "HE" (High Efficiency) models are $575:
http://www.chiefaircraft.com/aircraft/oil-system-filters/oil-coolers/he-series/aec-8001646.html
Any thought's on either of these two options? Pros and cons. The HE models look a lot like the S&W model I have, assuming the pictures are accurate.
Thanks for the feedback.

for what it is worth, I see nothing wrong with welding it. but you need to correct the real problem that caused it to crack in the first place. It maybe flexing or vibration mounting etc. but something caused it.

I thought the source of the cracking had been addressed. I had some issues with the left-rear baffle flange cracking too in the beginning. I made the rear baffle nice and strong, but used the stock left-rear piece which was .032. It just wasn't up for the task. I later added a cross strut from the crankcase just ahead of the hoist loop all the way back to the left rear corner and added some .063 angle stiffners over the oil cooler flanges for additional support. I'm wondering if I cracked the flange today taking the oil cooler off. It was pretty stuck on and I was having to do a fair amount of prying to get it to separate from the gasket. I would have been more careful if I'd of realized those flanges are made out of such crappy pot metal. Man, they are soft.
Since I'm rebuilding, I decided to rebuild the left-rear baffle part and was taking the oil cooler off today to accommodate that. That's when I noticed the crack.
Attached are some pictures of the setup prior to disassembly today.

I certainly recommend talking to Pacific Oil Cooler before you make any decisions. They can give you pricing to repair, and probably have a source for exact replacement as well.

My first choice is engine vibration, and the second is stress due to the baffle mounting flange not being flat.

Matt-
I see the probability of much motion in that area what with the sheet metal carrying the load and a long vectored brace like you have swinging it. I can show you a better way to mount it if you contact me directly or you can take some other advice that I'm sure you will get from the listers.

Matt,
A few thoughts:
- Mounting the cooler on the firewall solves the "heavy vibrating object
mounted with a large moment arm" problem. Attached photo is how I did it on
the RV-10 (not shown is the forward cooler support attached to the engine
mount). On the RV-8A I mounted the cooler on the right side of the firewall
with the 3" hose connecting on the right side of the plenum. I believe most
8s are on the right side as there is more room.
- Mounting the cooler on the firewall allows for an easy "oil cooler air
butterfly valve" install in the 3" hose between the cooler and firewall.
Here is one place to get this butter fly valve:

1ef861c7cd83d92c5a28010dc
- Consider using the AirFlow oil cooler if you end up buying a replacement.
I have this on my RV-10 and have never had a oil temp issue. Here is one
place to get this cooler:
