My timing belt broke on my 87 Integra. (DOHC) I've replaced the belt but can't get the timing right. I've aligned the crank to TDC, I've indexed the cam pulleys to the proper marks, (notches facing eachother and the "up" marks pointing up.) but it's running like it's still off time. I've been told that having bent a valve is VERY unlikely, but I'm beginning to wonder.... Any suggestions? Thanks, Brian.
