I talked to Gordon at WitchHunter.com, who will clean, Repair, & Rebuild your injectors. He tells me the little plastic thing that gets stuck in the intake after you remove the injector is called a "pintle cap" and he replaces those with an injector rebuild. So if there's a plastic cap on the injector tip, there's no o-ring.

What's that little roundish plate in the middle of the intake for? I can't mine off.

TomoHawk, there is a seal(o-ring) too

Look at the FSM, both the cap and the seal are called for!

I have never pulled an injector that left its cap in the manifold. I have pulled some with a cracked cap.

The plate in the middle of the intake is for dinner! Actually, if you are talking about the plate on the top of the manifold between runners 3 and 4, I think it is to keep the heat from the exhaust from flowing up through the manifold, but that is only a guess. There is probably a much better reason having to do with some option somewhere, I don't think Nissan would have taken the expense to put that hole there just to have to put a little more money in making and installing a plate over it!

Uh oh...

I will have to go back to the hangar with a light and a magnifying glass to see if the o-ring is still in there, because I definitely didn't see any on the injectors that are on the bench. and I will try to get under and look up there to see what the hole is for. Maybe a mirror will help. Something to do with a pre-heater maybe?

Good info, thx.
