ARRRRRGGGHHH!

After realizing I had a bad seal on one injector at the manifold mounting rather than the fuel rail mounting, for the second time I might add (same injector), I decided today was the day to straighten that out. Took off the rail, replaced all 8 seals, rings and plastic hats, replaced the rail and injectors.

Same problem!!! There is fuel swelling up around the manifold connection of injector # 3 (counting cylinders with #1 at the back).

This is the same original problem, it even seems worse now! Damn!!!

After coming home and pouring a nice stiff vodka tonic, I'm wondering what to do. The gas that is coming out makes me nervous, it is actually dripping, slowly but steadily, down the intake runner to the side of the head.

A leaky injector?? I'll check the top new seal at the rail and see if it's coming from there, but I'm sure it's swelling up from the manifold hole.

Maybe someone was aggressive in cleaning out the manifold hole and opened it up a bit?

Sh*tty aftermarket injector seals? The other three are o.k.....

As a quick fix, what sealant would you recommend to put around the injector/manifold connection that would hold for a week/month/day?

I appreciate the advice and / or speculation....


Thanks, Josh
