Fuel Inj Question
I pulled out the fuel injectors and broke the white plastic cap things off the ends of the fuel injectors. Does anybody know where i can get some new ones?
I think the purpose of these plastic caps is to keep the lower oring from slipping down. I put them back in and 2 days later its running on 5 cylinders. I pull out the fuel injector on the cyl that is missing and the f-ing oring has slipped down and it starts pouring gas down into the cylinder. I push the oring back on and put it back in and works good for 2 days and it starts all over again. |
They're called pintle caps, and they are more so to help the injector itself, not the o-ring (IIRC). I just yanked a pintle cap off of an injector I have laying around, and the o-ring won't go past the ridge on the bottom of the injector (where the pintle cap attaches) without some force.
Did you lube up the o-rings before reinstalling the injectors? You can usually get the pintle caps in injector o-ring kits from an auto parts store. |
Excuse my ignorance, but does a broken pintle cap even matter? I've used many injectors with broken pintle caps in previous maximas and I've had no problems with them. What purpose do they serve?
