I have an 87 civic I bought last year. I'm having some issues with the compression. The first cylinder has half compression, the second and third cylinder have 0 compression, and the last cylinder has full compression. I can't find any resources for how to pull the head off and check the pistons. There are vacuum hoses everywhere and it's a bit hard to see what's holding the head on other than the timing belt and the torqued bolts under the valve cover. Any help would be greatly appreciated.
