High CHT

I have a c182S. 2000. My numbers are almost identical. Any answers.

Hi Elijah
Compressions are good.....all either 76 or 77 this past August.
Oil consumption about 1 qt/ 10 hours

What's the compression in cylinder 4? I've experienced a cylinder not breaking-in properly - which resulted in ring blow-by and comparatively higher CHT from the rings not seating.

I do partial cowl flaps but if I have them closed too far they CHTs go over 400 and I have not had thee guts to see how far up they go...

Thanks - missed that inner baffle part. I will pull the cowling and take a closer look.

Thanks.

Hi Steve
I will do the light test.
Also, I had been thinking about a typical cruise flight with cowl flaps closed to see where the temps settle.....I'll do this as well.
Will post my findings for both in a day or two.
I did a borescope a couple of months ago....concentric burn on exhaust valve and x hatching on cyl walls, so figure that is good.
I can't help thinking/hoping it is a cooling issue...if so. I will find it.
Again, thanks for all the input.
Steve
