how do i replace injector seals for my 92 cavalier 2.2l?

Question

i can smell gas before i start it after a short trip.

Answer 1

It's actually pretty simple. You have the bottom feed injectors. basically remove the upper intake manifold, remove the pressure and return lines including the pressure regulator and then remove the injector retainer bracket. Disconnect the electrical connectors and pull out the injectors.

Assembly is as they say, reverse of removal. Make sure you lubricate the new seals so you don't cut them going in. The whole job takes an hour, tops.

Answer 2

I agree with most of the post above, but I have to laugh at the "hour tops" comment. Maybe for someone that has done several of them, but the first time will take at least 2 1/2 hours or longer. Book time is 2.4 hours so I know a novice will take longer. Take your time because the clock or flat rate is meaningless when working on your own car, but doing it right is the important thing.

Between my wife and I, we have owned 5 Cavaliers including a 92 with the 2.2L that I maintained from end to end and sold with 122K. Anyway, I ran into the same situation and it turned out to be a broken diaphragm in the fuel pressure regulator. it caused the fuel pressure to be high all of the time causing the injectors to leak. I would replace the seals and the pressure regulator at the same time. If you just replace the seals, and the fuel pressure is high 100% of the time because of a bad regulator, they will leak again sooner than later. Not to mention provide you with poor fuel economy and possibly a rough idle. It's about $65 at autozone. If you don't replace it, at least check it with a vacuum pump. I hope that helps.

Your car is probably throttle body injection , which means you only have one injector. The reason you smell gas may be that it is leaking,ie dripping from the pressure left in it when you shut off the engine. It may need to be changed,it doesn't have a seal because it is not in the cylinder. After removing the air cleaner there should be a Torx head screw to remove and then carefully pry out the injector.
Actually you might try running some Berryman's B12 through the gas tank to clean out the orifice. It's a stretch but you could have junk in the injector preventing it from opening and closing all the way.
Good luck ,hope this helps.

please don't do it, unless you know what you are doing. Plus, I wouldn't hold onto the cavalier. I wouldn't go into much detail, because it hard work. Especially when dealing with the injectors, chevy has that bad problem with their injectors.
