Our new-to-us Aztec is running some fairly high oil temps (am ashamed to post numbers) that don't show any signs of decreasing. It's bad enough that 20" MP and 2300 RPM requires full or partial cowl flaps to remain <220deg in cruise. We've worked on the baffling and I'll work on it some more this weekend. What about the oil cooler? Do those get clogged internally? We have decent oil pressure even at the higher temps but I'd really like it to run as cool as the other motor. We run 100W (east texas area)

thoughts? Suggestions?
