Hey all, I am replacing my valve cover gasket on a 1991 Civic 1.5 twin carb. The cover is stuck fast as it looks like the old one was installed with sealant. What is the best way to pry it off?? Also once off, I have to replace the plug tube seals. Are the tubes attached to the valve cover or the head?? If they are attached to the valve cover, how do you remove them to replace the seals?? Thanks guys for ya help.
