Listers:

I am seeing real high oil temps on my IO-360, Lycoming in my RV8. 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?

Thanks

Al,

Check to be sure that nothing has clogged your oil cooler intake. 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.

Al, this is common on the angle-valved engines.  They just put more  
	


heat into the oil.  I'll send you some photos of my (not original)  

solution off-list, but you can find the same info on doug reeves' site.

270-F.???   I'd check your Temp Sensor first as  that sounds awfully high for any  installation (especially with a 9 row cooler)!

  

 do not archive

Someone told me that early cowls had a 2" exhaust opening and that caused 

some problems and this was later changed to a 3" opening.  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

Al,

I experienced the same problem when my RV8 was new.

Tilt back the Oil cooler approx. 25 degrees.  Make the brackets from 030 or 

040 4130 steel.  This fixed my problem.  1350 hours on this set up.
