Avoid Injector O-Ring failures. Here’s a quick tip that may help when installing injectors.

Jay, for what it’s worth, local parts stores do carry injector o ring kits. Maybe not for all types but the ls crap I have they do.

Good idea to use lubricant, I hadn't thought to do that. Would something like NAPA Sil-Glyde work?

Another thing to watch for is the RIGHT SIZE O-ring too(!!!) - we ran into this with my nephew's 5.0l SBF, we cut a few O-rings(vasolined up and all) trying to reseat the awful cheap fuel rails that the previous owner had used and went to the auto parts store to pick up a new pack of injector O-rings. Specifically packaged and sold for the purpose, they weren't just random packaged O-rings. But, when we put them on the injectors, they fit pretty loose, both the O-ring cross section was a little too small of a diameter to fill the groove in the injector body and the O-ring's internal diameter was a little too large for the depth of the groove in the injector body, was definitely a no bueno. Ordered the RIGHT right ones online, fit like a glove.

This is NOT an area where you can fudge it and cut corners - not paying attention to your injector O-rings can be a great way to burn your car to the ground

I keep honda brand silicone lubricant. Stuff is awesome.

Hmm, some articles say to NEVER use silicone-based lubricants, as the heat and pressure will make the silicone clog up the injectors. Also, they say silicone fumes or greases destroy oxygen sensors, hence the oxygen sensor safe RTV silicone sealant products that you see for sale They recommended only engine oil or your car's type of fuel.

Can I use petroleum jelly on any o ring on trucks? Filters included??

Question: I have an SC 2JZ that has a blown headgasket and is hydrolocked. The Torque Converter is still attached and the motor doesn't turn. Don't give a damn about internals, cause I'm probably going forged. The question is can I salvage the block?

Silly question, do new injectors come with the o'ring or is it necessary to buy a separate o'ring kit? Thanks for this video.

I prefer to use fuel itself as a lubricant
