Hi Sean, My name is***** will be glad to try to help. Could you please upload a picture using the paperclip icon of the weep hole you are referring to in the head to be sure we are both on the same page for the source of your leak
Thanks for thew picture. Is fuel coming out of that hole or spraying there from one of the fuel lines? If it is coming from inside the head you are correct that you have likely failed injector o rings or a faulty injector. apply air pressure to the fuel rail to confirm.
Thanks for the info. Remove the valve cover and look for leaks under the valve cover at idle.... do not put your hands anywhere near the high pressure fuel. Let me know
Hi Sean, Did you get this resolved?
