injection housing leak
After a hard drive i noticed some oil on the right side of inj housing. It looks like there is a leak from the gasket. Time to pull housing and replace the
gaskets. Should i replace the o rings on my injectors while i'am in there. Injectors are from FIC installed some time ago. I ordered new housing gaskets and plenum gaskets, but forgot to order o rings. Do i replace only the primary or do all of them. Thanks John |

FIC injectors come with new, Viton o-ring seals, except for the primary injector lower o-ring seals(8), Jerrys Gaskets PN 10067600-V. If you are not sure the o-rings you have presently are Viton, I recommend replacement. The rest of the o-ring seals are OK for re-use provided they are not damaged. Lightly lube all of the o-rings with motor oil before re-installing. Do not use silicone grease.

I’m curious why you recommend not using silicone grease? H

Re: injection housing leak
Silicone will damage the O2 Sensors.

Re: injection housing leak
Actually Jerry my understanding is that silicone kills the O2 sensor, not the converter.

Re: injection housing leak
You are right Dom, my mistake. I knew that but it just didn't come forward when I was recalling the issue with silicone. One of those symptoms of age.. Thanks for calling it to my attention.
