Default Injector issues. Leak? costin me $$


Was taking a peak at a couple of my injectors and they appear to be leaking. One for sure is pretty wet around the base and another is leaking somewheres closer to the top. and the others i didnt get close enough.

Im getting RIDICULOUS mileage, like 20 bux, is like 75 km's. I ordered a new O2 sensor.

I get outta my car and i smell like exhaust/gas. in a drivethrough i can smell gas.

i checked all other areas and im not leaking it, such as lines or tank or filter etc.

its drivin me nuts.
any takers

Usually injectors wont leak around the bottom, they usually leak up where it seals to the rail. Try replacing all the o-rings on them. Theyre cheap and easy to replace.

As for the mileage. I doubt your leaking that much gas and its not pooling someplace. THats a couple of gallons going missing.

Make sure that injector isnt stuck open, if that happens, you will be leaking some serious gas, but into your engine and out the tailpipe

use some penetrating oil to get them out and twist them around a little before you pull them out to not break the pentel caps.

Also, when re-installing your injectors make sure you lube the new o-rings. I usually use pentrating fluid, if you dont, youll tear the new o-rings and all of your work will be for naught.
