In the 270degree range. I have the 9 row oil cooler mounted on the rear baffle. This is a new engine. Any suggestions on what to look for? Better oil cooler placement?

We had high temps in the beginning and found that we had sucked a piece of paper into the intake. While we had it apart we increased the size of the intake.

I'll send you some photos of my (not original) solution off-list, but you can find the same info on doug reeves' site.

I'd check your Temp Sensor first as that sounds awfully high for any installation (especially with a 9 row cooler)! do not archive ----- Original Message ----- From: Al Grajek To: glenm@sealritedoor.com ; rv8-list@matronics.com ; scottr@vansaircraft.com Sent: Friday, July 21, 2006 7:32 PM Subject: RV8-List: Oil temp problems --> RV8-List message posted by: "Al Grajek" Listers: I am seeing real high oil temps on my IO-360, Lycoming in my RV8.

I also set the cooler back from the baffle by 1/2 inch and it's tightly sealed. Just something to check. My IO360A1B6 with the 9 row cooler and high compression pistons rarely gets over 200 degrees (hot day full power climb at less than 100k IAS for several thousand feet) Good luck Paul Schattauer RV8 808PS >From: "Al Grajek" >To: glenm@sealritedoor.com, rv8-list@matronics.com, scottr@vansaircraft.com >Subject: RV8-List: Oil temp problems >Date: Fri, 21 Jul 2006 21:32:45 -0400 > >--> RV8-List message posted by: "Al Grajek" > >Listers: >I am seeing real high oil temps on my IO-360, Lycoming in my RV8.
