Digging into this a little more, I think we should note that you're running these engines fairly hard:
Cruising at 25" - 26" manifold pressure, 2450 rpm, 3500' msl, etc. That would put you over 80% power I believe.
Through all this I see that you're running 110 degrees oil temp on the front engine and 128 degrees on the rear engines which is good news. The low oil temps mean that your rings have sealed and the hot combustion gasses aren't getting by them and heating up the oil. Also, I'll bet that fixing the rear baffling helped those rear oil temps get close to the front on your last flight.
How's your oil consumption?
