Narrative:

I was flying at cruise power setting when I noticed that the cht and iegt readings were well above normal! The engine seemed to be running rougher than normal and the cht reading did not go down with a reduction of power. I was over mountainous terrain with the nearest airport about 8 NM. I saw an open area below that was part of a dirt road and decided to make a precautionary landing. I made an uneventful landing on the road and after some time the engine and cht/egt appeared normal. I saw no one and decided to take off. After climb out, I noticed the cht and egt climb very fast and as I circled near the landing area, spotted a vehicle. The cht and egt remained high and I decided to land and ask for assistance. My second attempt to land was too fast so I decided to abort the landing attempt. On climb out I stayed close to the landing area and the cht and egt began fluctuating up and down. On reaching about 8000 ft MSL, I flew to the nearest airport and landed. The cht/egt began reading normal and I did not notice any indication of heat on landing.

Title: A HUSKY 1 PLT MAKES AN OFF ARPT PRECAUTIONARY LNDG WHEN HIS CYLINDER HEAD TEMP INDICATOR READS HIGHER THAN NORMAL AND THE ENG APPEARS TO BE RUNNING ROUGHER THAN NORMAL NEAR Q99, CA.

Narrative: I WAS FLYING AT CRUISE PWR SETTING WHEN I NOTICED THAT THE CHT AND IEGT READINGS WERE WELL ABOVE NORMAL! THE ENG SEEMED TO BE RUNNING ROUGHER THAN NORMAL AND THE CHT READING DID NOT GO DOWN WITH A REDUCTION OF PWR. I WAS OVER MOUNTAINOUS TERRAIN WITH THE NEAREST ARPT ABOUT 8 NM. I SAW AN OPEN AREA BELOW THAT WAS PART OF A DIRT ROAD AND DECIDED TO MAKE A PRECAUTIONARY LNDG. I MADE AN UNEVENTFUL LNDG ON THE ROAD AND AFTER SOME TIME THE ENG AND CHT/EGT APPEARED NORMAL. I SAW NO ONE AND DECIDED TO TAKE OFF. AFTER CLBOUT, I NOTICED THE CHT AND EGT CLB VERY FAST AND AS I CIRCLED NEAR THE LNDG AREA, SPOTTED A VEHICLE. THE CHT AND EGT REMAINED HIGH AND I DECIDED TO LAND AND ASK FOR ASSISTANCE. MY SECOND ATTEMPT TO LAND WAS TOO FAST SO I DECIDED TO ABORT THE LNDG ATTEMPT. ON CLBOUT I STAYED CLOSE TO THE LNDG AREA AND THE CHT AND EGT BEGAN FLUCTUATING UP AND DOWN. ON REACHING ABOUT 8000 FT MSL, I FLEW TO THE NEAREST ARPT AND LANDED. THE CHT/EGT BEGAN READING NORMAL AND I DID NOT NOTICE ANY INDICATION OF HEAT ON LNDG.
