I have had a small leak on my #5 fuel injector for some time. I can tell because every oil change I see dirt collecting below the injector on the intake runner.

I wonder if this is a simple repair like a new o-ring or is it time to rebuild/replace the fuel injectors now that I have 130K on the clock?

Thanks

Pulling fuel injectors is a pain because of the 'quick release' fitting for the fuel line. If there is physical fuel leaking, it would have to be either from the top O ring or the injector body is cracked. The injectors are not normal replacement parts, they usually last longer than the valves. Same for the O rings, unless they are disturbed.

I would look for a leaky oil filler cap seal first. They need to be replaced every other year at the latest because they dry out and get brittle.
