B) Hello dear friend the fault you are experiencing rather it is an empty leak in the fuel feed system to the injection pump ...
Recommendation: 1) Check if you find losses of fuel on the housing of the injection pump.
2) Place a transparent hose from the fuel filter to the feed inlet of the injection pump, verify if the fuel with bubbles with cosntant air bubbles.

In the case of observing losses in the injection pump, it must be taken out and perform basic maintenance work (change of rubber stamps, withholdings, accelerator and washers

Good, thank you very much for your response, I will check that but Ed Anyway I believe and I still insist on what I say .. for me it is for the injector where he takes air and makes the fuel back up .. since one of the return hoses, when everything is armed (it was disarmed because the joint was breathed because they put a joint that did not go) Oil upwards .. After adjusting the hose I kept splashing the same, so I took the work of washing the entire full engine and drying it with the compressor to see if I kept losing and since I did not lose anymore, I

thre Base of the injector, takes something else like the orings (rubber washer) in the middle as shown in the photo ???? Thank you many to all

Good, in case someone reads me, I tell you that I think I am on the right track, find out that the injector carries an orrin orrin as a friend tells them, but that this is not the one who does that the pressure does not come out, the one that is in charge of that is the conica washer that apolla at the base of the cover and seal everything ..



If

I can get them, I will realize that it happened that it happened that it happened. If anyone knows .. anyone has an idea because it can leave white smoke? especially when it turns on and when the engine works a little more .. precisely long in 3rd and when I hurry .. I already put maximum compression wins and the same .. well I expect answers or ideas even if not precise people help people:) thank you

Estimated, in my humble opinion and I hope they correct me if I am in error, as our friend Ecnop said, I think your problem does not lie in the injector, in simple words, you must have pressure problems between pump and pond being its intermediary the filter with its respective priming pump that also acts as a "retention valve" preventing the fuel Filter. Regarding the return hose, it has no greater incidence in motor performance thus discarding the white smoke that I think is only air in the injection system
