I have recently found that the leaking injectors on my 944na, is caused by a break in the seal between the nozzle and the body.looks like a design fault,that also causes the nozzle to rotate freely inside the lower body. I m wondering if anyone else has seen this,as a german guy on a german forum claims that neither he nor his fellow members have ever seen this. I cant believe two out of my four injectors are the only ones in the world with this problem.I tested for this by putting low pressure about 2lb psi into the inlet and dropping the nozzle end into petrol, low and behold I had leaks from the aformentioned joint and also there was leak by on the nozzle itself, which means this being a common rail system, there must be dribbling from the nozzle all of the time,makes me wonder how many dribbling injectors are out there.I would be interested to hear any feed back on this

My fuel injector log developed a hairline fracture that caused it to leak at the junction between the square body and one of the injector nozzles, right where it is either brazed or welded to the body. It caused a microstream of fuel to leak when pressurized. I picked up a new used unit at Parts Heaven a while ago for under 50 bucks. It's perfect now.
