I have a 1988 iroc tpi 350 186,000 miles on engine. 2 of my injectors are leaking, for #7 and #2 cylinders . Would it be the injectors themselves or the O-rings on the fuel rail (gas is leaking from the top of the injectors, look like where the injector connects to the fuel rail) and how could I tell if it was the injectors. Also where can I get injectors on the sameday of fix. Autozone and O'Reily have to order them down here in Houston TX. Thanks John

 

If gas is running down the outside of the injectors from the top, I would have to say the o-rings are shot inside the fuel rail. For it to be the injectors leaking that way, the tops would have to be broken. Also check the 4 bolts securing the fuel rail to the intake manifold for tightness. Should be tightened to 15 foot pounds.

Trickster The bolts were the first thing I checked cause I didn't realy want to pull the plenum and runners off but I guess I'll be do it this weekend, appreciate it. John

 

I can feel the pain and sympathize with you John, been there and done that several times and it didn't feel any better at any time.

Just think of the good points though, not the pain and agony you will go thru. The O-Rings are a lot cheaper than injectors.
