Drivers Side Cylinder Head Noisy

[95_GTS]

So here I was troubleshooting Code 122, where I determined it was a bad TPS. As soon as it ranked up after sitting for a few days, the RPMs jumped to @6K. So I immediately shut the car off, performed a quick visual, and found the Cruise Control arm flipped around and hung up on the EGR tube.

I started it back up and at that time is when I noticed the driver's side cylinder (AFR 185) head was noisy (ticking/clacking).

Possibly a valve spring broken?

Thoughts?

One way to find out for sure: crack her open and look/poke around. I had a similar sound on my AFR heads on my old ‘64 ChevyII. Turned out to be just a loose rocker arm. Ez Pz

Got her back apart and found out 90% of them on both sides are loose, especially the driver's side where all the noise was coming from.

I also noticed that a lot of them were not perpendicular with each other.

So I should loosen each one, verify lash, half turn, lock it down, then another quarter turn?

It wouldn’t hurt to redo them all, yes, just for assurance, especially since you’ve got the cover off anyway. In the case of my ‘64, I just tightened the nut back down to spec, rechecked same on the remaining rocker arms and buttoned her back up. Fired it up and was smooth as silk!
Good luck, I’m sure you’ll be fine so don’t stress or over think it.
Cheers!

Let us know how it comes out!

Hey Daryl, did you go through the whole firing order as you retightened?

No sir. Admittedly, I went straight to the bad one, torqued it to spec THEN went to the rest

Unrelated, but my first car was a '65 ChevyII.
