Question Broken valve spring on E6 cylinder head

I am trying to buy a new spring for my E6 head on my car but im not what size or if its exhaust side or the intake side?

if i am looking at the cylinder head on the drivers side at the #7 spark plug the right spring is broken and needs to be replaced i am not sure which one that is?

asl when i replace the spring what else needs to be replaced with the spring?
The head is still on the car,found this out from no compression in #7 cylinder...

broken spring=good possibility of a bent valve and/or piston damage..

you may be in for some major repairs..better take the head off and check...

you've got quite the mess on your hands lately...

is there any way to check without taking the head off? hooking up the air compressor and taking the rocker of and pulling the valve stem through possibly?

you should be able to lift the valve up with your finger once you take the broken spring off..just dont drop it down into the cylinder

..but what good is that going to do if the piston is cracked?

you could upgrade to e7 heads or gt 40's..you could probably get a set of E7's for free lol

Because it broke doesn't necessarily mean contact has been made, there's a term called metal fatigue.

If they're E6 heads, I'm guessing it's the springs that came on them? :?: If yes, then it's probably fatigue.

What you do is try to lift the valve up even with the spring on it, just to see if the valve moves. If it does, then change the spring.

To determine which it is, look at the header. If it's in line with the header tube, it's an exhaust spring. If not, then it'll be in line with the intake port. I'm guessing it's an exhaust spring since they take more abuse than the intake.

If you change just the spring, then I would suggest change the retainer and locks with it to make sure you don't have a mismatch.

Edit:
If you really have a broken spring, it'll barely run at all because the valve will be open all the time, causing a dead cylinder.

If you can't raise the valve then contact has most likely been made and bent the valve. Sounds like the head will be coming off and a valve replacement along with a new spring is coming up.

i'd bet you could get someone's E7's cheaper than a new spring/retainer/lock setup..but it sounds like theres bigger problems inside..
