[Solved] Lubricating New Injectors

I'm using Timmy's video to help me out. He uses gasoline on the injector seals. Is there any reason why I cannot use silicone lube?

 

Why use silicone lube and possibly contaminant the gas and injectors when the Toyota repair manual specifies using gas to lube it when installing?

The gas is just used to not break the seals while installing them. There's no need for ongoing lubrication.

 

I used a cup of gas and dipped the injectors in when replacing the seals.

Make sure you install them with a twisting motion or it will leak.

 

I used a thin coat of Vaseline and it worked great. Ended up swapping/replacing injectors a few times to isolate the problem and it worked well every time. Probably gives you a little more time to align the fuel rail w/o the gas evaporating and thus losing your lubricant.

 

I prefer non-petroleum products on rubber orings.

Professionally I use sylaglyde on my injector base seals. On the smaller orange ones I use silicone spray.

Oil causes swelling on orings so I stay away from them.

 

I have heard dish soap recommended before.

Across 5 car clubs around the globe, I've seen a bunch of different and sometimes crazy remedies. Everything from KY jelly to Swiss Navy silicone lubricant.

That's exactly what I was thinking. I don't see how silicone would damage the rubber seals, but I'll try the gasoline anyway.
