My car had a dead cylinder and the plug was firing. So I limped the car and I had an injector get stopped up by some aluminum from my fuel rail. I cleaned out the injector and put everything back together. Now the cylinder is still dead so I do a compression check and it shows half of what the other cylinders show. I pulled the head off and the cylinder wall and piston looks fine from up top. I flipped the head over and pour some gas in the chamber for a ghetto leak down test. Turns out I have one bent exhaust valve. The question I have is how did only one valve get bent?

edit:ITR cams and RS machines type R pistons btw

You may have a broken valve spring. Especially if you aren't even using upgraded springs but revving higher than stock. If not broken it could just be down on pressure. I'd say disassemble it and take it to a machine shop and have them check all the springs. You'll probably want to check the rest of the valves a little more thoroughly then have the guides checked out. Ever so slightly valves that are bent but still sealing are hell on guides.
