Torment

Smelled strong gas smell. Found the source was the front injector on drivers side. It was actually causing a puddle of gas.
Replace O-ring in injector. Still smelled gas and still puddling.
Second O-ring kit. Still smelled gas and still puddling.
Replaced injector. Gas smell and puddling still a problem.
I've become quite proficient at removing the plenum.

What is next? Fuel rail a problem?

To do a full reseal, you need 3 o-rings for each injector. First, the insulator int he manifold. Pull the old ones out. They wil be shot and creating an air leak. Next if the cusion rings. Keeps the pressure on the injector so it doesnt rattle around. And last, the main seal ring. Always use some silicone spray on these before inserting them in the fuel rail. I doubt its the rail itself. Now dont overlook the puylsation dampner. Its located int he back of the fuel rail, pass side. Basically where the feed line hooks to the rail. Oh, remove the plastic cover before unscrewing it, if you dont, you will beak the blue VSV. And if you remove the plastic cap and a srew falls out, replace the damper. These trhings are prone to leak!

pull them all.. Send them to witchhunter.com for cleaning, testing, & new o-rings.
Cant beat $15/each.

Did the full reseal. Found some bubbles coming from the replaced injector. Guess it was bad. Going to try again.... One more time.
Noticed the reman. injuctor had different seals than the one that came out had. The cushion ring rubber was too thick and wouldn't let the injector set in the insulator correctly. What is the part number for the correct kit? Is the o-ring kit pricey?

I know the leak is coming from the top because the whole injector is wet with fuel, even where the plug is.

NAPA has a kit.. I think it's around $6. I don't have the part number.
You can look it up online.
