Default Injector oring

I'm in the process of installing my injector cups and I've read to put vasaline on them I've also heard I need to use loctite or rtv just curious before I install them

Vasoline, silicone will be a royal pain to clean out of the bores. make sure to use new o rings and injector coppers not reg copper washers.

I put oil on the o rings and red loctite on the end that seats in the head, install cup, install injector and torque then let sit for 24hrs before I fire it up.

Everyone has their own way though.
