i used a long flathead screwdriver, hammered it into the cap and yanked it out.
getting the new one back in is a bit trickier as there isn't much space.. took me a few tries to push it back in with a rag

 

ohhhh ok so basicly u gotta try and pry the old one off or break it or something right? also can i put some sillicone sealant on the new cap? or just put it in dry?

 

yeah, the cap looks like this


as you can see on the back of the head it sticks out a little bit, just enough to jam something in there to pull it out.

i used some sealant but it turns into a mess quickly so don't stress, take your time, and push the new one back in.

will be a lot easier if you remove the valve covers, just be mindful of any dirt/debris

 

alright thanks man i aprreciate the help!

 

I did mine also with valve covers off. I didn't use any sealant on the caps.

 

alright... i guess im going to do this while doing my valve cover gaskets too then haha...

thanks again guys
