I have a new set of RV275 injectors mocking me from the workbench because I can't get any of my injector line nuts to break loose from the head. I hit them with PB Blaster last night with no luck. Since they don't look like the most sturdy things on the planet, I don't want to force the issue. Any bright ideas?

 

Get a piece of pipe and slip over your wrench and just take it easy. I have never had any trouble with mine.

 

I'm just being cautious, they look like parts I don't want to round off with a wrench. I think the PBB is starting to work its magic.

 

Day 2 and the PBB has finally done the job. I guess I should have planned ahead just a bit.

 

Make sure to torque those nuts to spec when you are finishing up the install!

 

Agreed, that's why I'm being careful during removal. Those just look like parts that are a pain to replace if boogered up.
