I have a 1987 turbo two.. I put all my injectors back in and now the secondary injector closest to the water temp sensor leaks at the O-ring.. So, I take it off and put another o ring on... only to find a little later after it runs it is doing it again.
I did use a used o-ring to replace it with, but the first o ring was broken and the used one I replaced it with wasnt.. whats the deal?

 

When I had this problem, I found that the fuel rail was not tightened down enough. Also check to see if the grommets are in good condition. But check the fuel rail and make sure it is fully pressed down and that the injector is not turned to a bad angle or anything.

 

is the muff on the fuel rails damage ore got any scratchs
