fuel leakage again!

[digitaldrifter91]

alright i leaked fuel on my #4 injector last time so i took out the whole fuel rail and replaced every seal. put it back in and it was good. this was about 4 months ago

today i smeled fuel, not alot only a small drizzle....its comming from #4 again....***....should i replace it again just to be sure...though that one looks compressed more than the others...perhaps thats why?

now in doing so, should i change all the other seals again or leave them? since im taking out the fuel rail again.

o yea i had a cracked #1 injector but i got it comming in from someone so ill do that at the same time and then change my spark plugs to NGK for the first time.

possibly raise my timming from 15btdc to 16 stock.

thanks for the help

well i fixed the problem. i guess when we put it in something pinched the top of the injector and bent it a bit...but i bent it back and then put a new rubber and then put the injectors into the fuel rail and put it into the seaps. this way it wont damage.

before i did though i filled the injectors with some fuel injector cleaner, lucas. and then i put a little lucaus inside the intake manifold and the fuel rail to clean it out.

when the car started white smoke came out of the exaust, im guessing its carbon build up...i have to change one of the injectors for a possible crack. im thinking next time why dont i get a nice spray bottle and spray all inside the intake manifold and let it sit there for about 20 minutes.

do you think thats wise?
