injector lines leaking
I put a new head on, and thought I set the injectors and tubes back in properly but a couple of them are leaking under pressure. I thought it was the seat of the line to the tube at first but noticed the fuel only coming out the thread between the head and the ferral.
I just tried loosening the injectors and re seating the tubes but no good. #5 is the worst but #1 #3 #4 are weeping. Any thoughts or ideas will be greatly appreceated. |
sounds like you need new tube orings if its comin out around the threds
|
I did replace the orings that came with the head gasket kit??????
|
then i would probably try retorquing the injectors
|
Do you suspect its leaking past the injector o rings and not where the tube seats into the injector?? Or Could it have deformed "balls"on the end of the lines and not seating on the tubes properly. I have checked these for cleanes but just a thought....
I only have a 1/2 torque wrench so with the adaptors down to 1/4 drive should I allow a few pound in the torque settings????? very hard to find a 5/16 size socket in 1/2 drive.. |
over torque on the injectors causing the tubes to leak at the body could very possibly be the problem if you using a 1/2" wrench since they only torque to 89 in lb i would get new copper washers and retorque them with the proper wrench

Thanks for the surgestions guys. I loosened all the injector bolts off and retorqued them with a 1/4 wrench then swaped tubes, I put #5 into #3 and that seems to have stopped for now, Ill check it once I give it a road test, now the return 'T' is leaking so Ill look at that tomorrow.
01quadcab Yea I did remember about the grease trick. I found that I had better luck slowing the leak when I only "nipped" the swivel nut up than when I swung off of it... |
also, remember, the o rings only seal in the oil... they have nothing to do with fuel. I had a couple of tubes leak the first time I had mine apart, cost me 2 inj. tubes @ $50 ea. looking back, I probably had a bit of crud in the seat, and caused it to erode.

Well Im lost.... Fixed the return "T" leak then cleaned the seat on #5 tube again and put it back together and went on with the auto tuning Now after a week of driving, it doesnt leak any more..Im guessing the heat of the engine helped reseat the line to the tube.
So alls good and enjoying driving a ford with a cummins. Nearly got the auto sorted the guys at dieselconversions have been great. Hopefully be racing again soon...Cant wait.. |
