Hello Lance, When it was changed we had to order four cht screw in probes and two or three thermocouple wires. They came from the Australian agents and had the right part numbers on them so assume they were the right ones, they certainly looked the same. I have contacted the manufacturer and...

Lance, it has six thermocouple wires going to all six cylinders, all cylinder temps seem to be affected equally, there must be a master junction somewhere, possibly in the instrument.Ted

Found the answer. Nothing to do with the engine cowlings or anything like that. The instrument has became defective in some manner and changes, (reads lower) with an increase in cabin temperature. A heat gun under the panel very quickly caused a very large drop in indicated CHT's. Still waiting...

Lance, my curiosity got the better of me and I went out and took the top cowling off. The air intake for the cabin heating is actually right at the right hand front side of the engine, underneath the oil cooler and not on top of the cylinders as I originally thought. It is in a pressure air area...

Lance, thank you for your response. I will get the cowls off again early this week and have another look but I think, and another 182 owner could correct me here, that the cold air comes through a door on the starboard side of the aircraft and the intake for hot cabin air comes through a scat...

Thanks Joe B, I think that you are on the right track. I just wonder if the low temperature air, (ie OAT, perhaps 5 degrees) whistling over the engine, which is at 350 degrees, can contribute to the cooling of the cylinder fins by allowing a greater volume of air to pass by, that is greater than...

Thank you all for your responses. I have checked today and there is no connection between the cabin heat and the cowl flaps, they are well separated and movement of one does not effect the other. I can see no physical connection between the cabin heat cable and anything to do with the wiring for...

Lance and Dave, the change in CHT's is on all cylinders, not just the one. I can't see any physical connection between the cabin heat cable and the wiring for the instrument. For your info it used to be eight channels with 6 egt's and 2 cht's but I got sick of replacing egt probes and so...

I have a 1976 Cessna 182P, has 150 hours on rebuild engine with new Millenium cylinder assemblies. I recently installed at 6 probe digital CHT gauge which seems to work perfectly. The interesting thing I have only just noticed is that when in cruise with cowl flaps closed or nearly closed, the...

I ordered the cylinder assemblies as part of a complete engine overhaul package. After a few hours it started dropping out a cylinder at idle with a higher than normal manifold pressure. The engine people lowered the valve into the cylinder and gave it the gentlest of touches with the reamer and...

I have millenium cylinders on O-470S. Have only done about 170 hours on them, oil consumotion about one quart 15-20 hours, compressions all high 70's, (never had that before) sounds different but runs smoothly, only minor problem was two very slightly tight valve guides, needed a tiny touch of...
