Post by: RG8800 on July 26, 2011, 11:52:55 PM

Slight fuel leak from the exhaust manifold on my 730 Case.

Two possibilities Ralph. You have been running it too easy and slobbering unburned fuel, or you have an injector pintle not seating properly. Need to take it out and give it a good workout for half a day. Of course that manifold gasket ring is leaking so looks like only this cylindar is leaking. Replacing manifold gaskets is an easy job on this tractor.

Does it miss and sputter when starting when cold then catch on all 4 after a few seconds? Would indicate a dirty injector.

Gene, I meant to post more details last night with the picture but must have been half asleep. The tractor leaks like this all the time . I had been using it on the mower cutting hay before I took this picture. Not a heavy load for sure but running near to pto speed and I thought that might make it run cleaner. Did not make a difference. I don't know when it last had any work done on the injectors. Maybe it is time.
