WHAT CAUSES AN INJECTOR TO LEAK ? WELL AT AN IDLE YOU CAN'T SEE ANYTHING, BUT AFTER IT RUNS FOR AWHILE AND YOU KILL IT YOU CAN SEE BUBBLES WHERE THE NUT THAT TIGHTENS THE INJECTOR IS !

Might need to pull the injector and clean the injector bore,I would put new copper washers in to.You could try to just snug it down some and see if that help's.

Have you washed the motor recently? Is a valve cover leaking. If it's bubbling with the engine dead it is some liquid heatsinking my guess.

Yes I Have Washed It Just The Other Day, And The Valve Cover Leaks . What Do You Mean By Heatsinking? Thanks !

When you kill a hot motor it warms up 40+ more degrees than running temp. I would fix valve cover leak and wash again problem should go away.

is it diesel that is bubbling out? if so it could be the connector tube o-ring.

Worng forum- our injector lines connect directly to the injector body, no connector tubes.
