Hi All

I have and IO-550 G/N = Continental engine. Recently I had a fuel injector crack and eventually = break while torquing. The part number for the injector is 652312-612E = which is a tuned injector for the number 6 cylinder which was used in = the 2005-2007 time frame.

Attached are the = results of a GAMI LOP test which appears = satisfactory.

On = the first test we had the low boost on and the second test the low boost = was off:

1 - 9500 ft, 2480 RPM 11.7 gph to = 11.4

2 - 8500 ft, 2480 rpm 12.7 gph to = 12.2

My concern is when I am = taxing the number 6 cylinder temperatures are about half the temperature = for all the other cylinders, e.g., CHT 125 versus 240, EGH 425 versus = 880.

I know GAMI injectors would = solve my problem, but I would like to avoid spending $800 since my fuel = injectors were in range prior to the torquing = break.

My = question:

Will I cause = a problem for #6 cylinder in the long running with the Cirrus injectors = rich while taxing

Any idea what = might be causing the problem now and can it be = alleviated.

3. Any other = thoughts

Thanks in advance for your = thoughts,
