MF 65 exhaust leak around the seat of an injector.

MBU · Jul 13, 2016

I have a MF 65 tractor with a diesel engine. One of the injectors has exhaust coming from around its seat. What is the likely problem?

If the leak just started you might get lucky and see it stop by tightening the injector hold down nuts. If it still leaks the injector needs to come out, the bore/seat cleaned and a new gasket installed.

Thanks Dieseltech!

I cleaned around the injector and then removed and replaced its copper seal. That apparently fixed the exhaust leak. Thanks for your advice!
