Oil temps

Nice mod to the baffles, Jerry. I can see where it would make running the cowl seal material easier, but i am not sure that it would facilitate better air flow through the cooler.

I ordered goodies from Spruce yesterday. . will put the new cooler on next week and report back if there is noticable improvement.

Thanks to everyone who replied with advice on what i perceived as higher than desired oil temps. I bought the 6 row Stewart Warner and installed it a couple weeks ago. Both the trip to Oshkosh and the trip home happened on 90 degree days. Highest oil temp seen was 205 degrees. I believe that i have seen an honest 15 degree improvement.

engine temp on my rv4 is always a going concern for me[320 160hp] 0n hots days this time of the year 180 dgs but the winter time i plate my oil cooler and cover half of my cowl intakes and its still hard to get up to temp.

I was tooling along over Fisk Boulevard heading for runway 36L when the red warning light came on and this time, it was not switch the fuel tanks. After a long slow run up from Ripon/Fisk, etc. the oil temp finally reached 213 degrees for the first time. I realized that with my heavy load of camping gear and my hangar mate in the right seat, my angle of attack and low speed was not helping my cooling. By the time we reached home-built camping and turned off the engine, the temp said 217 degrees as I switched off the avionics master.

On the way home Wednesday, the alarm tripped again when we diverted around the west end of the big line of storms spread from Saint Louis to Chicago. It was really hot at our fuel stop near Brookfield, MO. The oil temp alarm went off during the climb to altitude. Up above the scattered layer at cruise altitude and speeds, all was fine as usual, around 180 degrees F.
