What lube to use on new injectors
 

What should I use to lubricate new injectors?

If you are talking about the o-rings - I just use a bit of motor oil. Seems to work fine.

Yeah, o rings.

Vaseline is a good go-to for any seal or "O" ring assembly.

silicone paste.

Where they sell silicone paste?

I use silicone too - I have a tube of paste I got years ago at an auto parts store. I was sold as brake mechanism lube for old school drum brakes.

I have some sil-glide I bought a long time ago. It is for brakes. Just didn't want it to slippery to seal. No pun intended. Well, maybe.

Home Depot/Lowes. Old silver dollar sized plastic puck with a pop top. Plumbing silicone for o-rings.

A little dab'l do yah.

Thanks. Taking apart tonight, can't wait to see what happens. If it changes any more, it will be a twin turbo. I wish!! This thing just keeps running better and better.

Any pool supply store should carry it. Smallest tube will be a couple of bucks and last a real long time.

This stuff good for all o ring slick em?

Old injectors are out. Should there be some back pressure when I broke the fuel line loose? On the fuel rail?

Dave, I just spray some lubricant on them and they slip in. Works for the heads or the rails. You sending them out to witchhunters for rebuild?

Hey Bruce. Good to hear from you!

Jaguar XJ6 1990 1992 Fuel Injector Bosch Free Shipping | eBay. Bought some here. For this price I will have spares. Yeah, will send them to witch hunters for a checkup.

Witch hunter just did mine. On the invoice it recommends just clean motor oil. I missed this note and called the shop who echoed this advice and added 'dont use silicone'. Honestly we are talking about the tiniest film on an oring so im not sure how big a deal this is... But i took the mans advice and they went in without drama.

Will try that this evening. Thanks

Any amount of silicone..could be just a very few molecules can kill an O2 sensor or even damage your cat. Don't use silicone sealants or lubes around your intake, exhaust flanges, etc.

Look for sealants that are labeled O2 sensor safe.
