It was close to 900 hours. This engine still burns about 12 % more fuel after the rebuild. Soot is not an issue since the rebuild except a very small amout upon acceleration. I'm either at 600 RPM or 2300 Rpm. Very seldom in between, I do go WOT for about 45 seconds on ocassion to "Blow it out". It was my starboard engine and no water in the oil.

The history of this C-7 has in it a head replacement at about 900 hrs said to be caused from a carbon build up on the intake valves, I have 1977hrs on the engine now. Before the high heat warnings occured the engine burned about 12% more fuel and would smoke a bit more than the starboard. The cockpit deck would get soot on it when running from 1100 rpm to 2000 rpm. Just wondering if you had the same issues before your cracked head was diagnosed and if it was the port engine. How many hours were on your engine when this happened? Did you have water in the oil?

Cracked cylinder head. Required engine haul that was not easy and a total rebuild. Had to strip engine to the block, attach plate to block to barely clear getting it out. Floor deck can be removed IF you don't have a tower.

At startup within a minute or two I get a High Heat Intake Air Alarm. I replaced the sensor to no avail but it did have quite a bit of carbon buildup on the old sensor. In the beginning I could shut down and it would reset after one or two attempts and run fine. It also bogs down and blows black smoke in the range of 1100 to 2000 RPM then catches up with the port engine and runs fine. Right now I'm not operating it until its resolved. I do have a call in to Alban Cat in Savage, MD awaiting a response and hopefully will be back boating shortly. Any ideas on this problem I can try in the meantime? Will post results once mission is accomplished.
