The topic could lead people to thinking somethign gross is coming up - but it's not.
I pulled my fuel rail today to swap out 17# injectors with 30# injectors. All was wel until I got cylinder 1 injector side out. I noticed the rubber seal on the tip was not present on that injector. I checked in the inake manifold and alas, there it was, all better! Not. There was no green spray tip on the end of the injector either and thus the reason the rubber seal was able to stay in the manifold.
It felt like I had an injector sticking - i would get a hesitation that felt more like a rich condition than a lean condition so i attributed it to my ultra high fuel pressure due to rising rate fuel pressure regulator w/ boost.
My question is - there was no tip on the injector when i pulled it out. That means either the angle i pulled it out in ripped it off and it fell down or it came off while the motor was operating. Unfortunately, the #1 cyl intake valves were open about 3 or 4 millimeters and I am worrying it slipped past them (i pulled the intake manifold off... what a PITA) and fell into the combustion chamer. I assume the sprayer is just plastic and so if it fell in the chamber it'd just burn to hell and whatver... but I am not totally sure.
Winfred, Bill R, anyone, have you ever seen this happen? Has the tips ever fallen off the injector and into the chamber somehow/sometime? Has a tip ever fallen off during removal and managed to slip through open intake valves? I looked in the head there and there was no sign of it - i gapped the valve its like 4mm, and the sprayer tip is like 4mm also, i cannot imagine it just falling in, but I've seen stranger ****. Any advice people?
Also - assuming the sprayer tip is plastic can I start the car? What would happen? If it's metal... which I hope to god it is not- what do you suggest?
