Oil temperature question

[Steve Pierce]

Those temps over ambient wouldn't bother me.

That’s about 115° over ambient, not bad.

How’s your CHTs? If they’re still up I’d still work on the lower cowl. Actually, I have a problem with improvements on systems that are probably good enough - I might still be working on it :lol:

Ya my CHTs are still 370-380, doesn’t seem to matter what OAT. I’m still going to try to improve on what I have but at least I can fly it when it’s hot outside!

There is nothing wrong with 370-380.

It's kind of the ideal target!

What they said. So long as you can keep them under 400 in a climb I’d be happy with that.

 

[Kid Durango]

Did you continue with the lip, or were you satisfied with where you ended here? Thanks!

I haven’t done anything yet, ordered an engine monitor and will install it prior to trying to make improvements. Temps are manageable and I think with a monitor I’ll be more likely to notice the smaller improvements.

Wes, when are you gonna be back here at TX00

 

[Schwarz]

I'll be in this weekend hopefully.

 

[SD cubman]

Wes, I have to go back north for a few days so I might miss you. This weekend

First thing I would do would be to get a manometer and see what kind of pressure differential on either side of the oil cooler. It is all about air flow and without modifying anything you can see what you have going on. https://www.amazon.com/Digital-Manometer-Pressure-Differential-Hti-Xintai/dp/B07KQVWFMK

Tom and I spent many hours troubleshooting a similar issue and documented it here.

I ordered one. It looks handy to have.
