Valvespring ? with Pics
My dad picked up his own TA (LE2 heads, LE1.2 cam) a few months ago and the car ran great. It needed a fuel pump and since we replaced that everything was OK until two days ago. Coming home he heard a tapping noise from the passenger side of the engine, specifically toward the #2 cylinder. He couldn't pinpoint it, so we started it up today (my first time hearing it run since the noise) and the noise wasn't there. There is definitely a miss, the car hesitates to pick up rpms. When he was backing the car into the garage, it was smoking pretty bad out of the exhaust. We got the passenger valve cover off and could only find this out of place:
The exhaust side retainer looks like it jumped off the center of the spring, none of the other springs look like this. The springs are Comp 918s, not too sure what retainers, etc. Does this look normal for beehives, I'm definitely not familiar with them? We're going to be taking the rocker and spring off regardless and checking to make sure everything is OK, but I don't think this is normal and am looking for opinions.

Thanks for the replies, we were talking about it being a bent valve earlier today. What exactly causes this to happen? Improper adjustment of the rocker?
I'll definitely post pics when we get the rocker and spring off.

A bad guide would let oil in which would explain the smoking. I thought most valves bend below the guide but I could be wrong, and the valve would still have to smack the piston for that to happen which is very unlikely unless there was a huge over rev or broken spring.

Took the rocker and spring off and here is what we found:
The valve and the guide appear to be OK, no excessive wobble, moves freely up and down.

Keep throwing springs at it, that wont fix the root cause of the problem.
speed_demon24(when he had LE2 stuff) and wrd1972 both had the same issues.
speed_demon24 changed heads and cam to fix it.
wrd1972 got off lucky just needing like 3 sets of springs and a new cam.
Can you see a trend here?
