Injector seals


A smoke test revealed 6 out of 8 injector seals are leaking. The question is which part?

This is the traditional one

others are recommending this one

I use pelican parts as an example.

Most of the cups, seats and O rings are all put in at the same time. If it were me, I would change all of them out of an abundance of caution. I am not spending your money, just telling you what I would do. Once you seat them, start the car and get the temp up good an hot to operating temps, then wrap them again to be sure they are fully seated as the temp change can loosen them when you once popped them back on a cold engine.
