I had the same problem--I closed off the air from #4 cylinder and= put in a naticu (sp) scope on the top of my cowling with a three inch duct= to the oil cooler--I have never had an oil temperature problem since doith= this.

Subject: [LML] Poor Slow-flight Cooling

Hi all,=

I have a Lancair 320 (IO-320) which I am just starting to fly "for = real" following 18 months of paint / renovations / panel upgrades since pur= chase.

During climb / cruise / descent all temps are as expected; ho= wever in slow flight oil temps rise rapidly even at moderate power settings= .  Never saw anything like this in my previous plane, a Lancair 235.&n= bsp; In the pattern on a "nice" day, if the downwind is extended significan= tly while gear is down oil temps approach the red by the time I land.
Air supply for the oil cooler comes from the aft left side of the aft engine baffle (3" hose around an oval exit), with an additional air feed (= 1 1/2" hose) coming from a small NACA duct on the left side of the cowl.&nb= sp; Oil cooler is mounted low on the left side of the firewall; air exits d= own into the low pressure area just above the air exit space by the exhaust= pipe.

Is this a common problem on the 320?  Is there a good fi= x?

Thanks,

Bill Reister
