Attention: TDR Forum Junkies 
When replacing 12v injectors it is sometimes difficult to get the leaks stopped.
A famous vendor told me 40 foot-pounds. Another tech found a value of 44 foot-pounds. Too much torque can crack the injectors.
I torqued this set to 45# cold and had leaks. Using compressed air on running engine, one can determine if the leak is line, return line, or injector. Supply line leaks are easy--tighten until it quits. Return line leaks are just as easy to fix--gently. Injector leaks requre removal of supply and return lines.
I retorqued to 45 and a nudge hot. Still have leaks.
I'm using new washers, new injectors, new cylinder head, and anti-sleaze on the threads. What to try now?
