Hi everybody,
A friend of mine has a beautiful 8 with a hard-to-figure oil temp problem. He now has a 13 row oil cooler for his angle valve IO-360 mounted on the firewall. He has also gone to 4" scat tubing and the vernatherm's been checked and works fine. He has a Sam James cowl and a Whirlwind composite prop. He used some wetsuit pants legs to connect the inlet rings to the plenum but they are somewhat constricted in the middle and smaller than the inlet openings by about a third. When I pressed on them, they easily expanded but I'm not sure that they do so in flight.
His temp on a 90 degree day stops at 217F which is not bad but could it be the intake restriction? What do you guys think? His oil lines are mounted on the upper rear of the case and I believe there's another possible location in the center of the case but it's not very accessible now. Could it be a plumbing problem?
Thanks in advance,
