I have an AP1 with ~150k.
My engine has always been noisier compared to other lower mileage s2ks but after a spirited drive one evening, ticking and squeaking noises appeared.
I've replaced the TCT with aftermarket and adjusted my valve clearance to try and narrow it down. Now I have a CEL for a misfire in cylinder 2 which could be that I botched my valve adjustment, but I cannot be certain.
There's been a time where I had a rather large oil leak and the car was driven (very slow and not far) with the oil pressure light on. So oil starvation from that time could have been a component of cause to my problem.
If anyone has experience fixing an engine that sounds similar to mine I would be eternally grateful.
Thanks for your help in advance.

 

I can't hear any abnormal ticking but hard to tell with internet videos. I can hear some odd sounding noise which could be the belt tensioner, try idling the engine without the serpentine belt for a few seconds and see if it sounds quieter, just for a short period of time enough to tell if the noises change. Squeaking noises tend to be belts, and you may also have some tensioner noise if the bearings are worn.

 

I can hear the ticking using earphones, the way it changes during the throttle blip doesn't sound too good.

In case dropping the oil pan and plastigauging the rod bearings is too much hassle, I would suggest an oil analysis.

If I am not mistaken, Billman once said, "The oil light comes on, you are screwed"

 

Pull the accessory belt and briefly run the engine. See if noise goes away. Sounds like it maybe a bad pulley bearing.

Good luck!

 

Thank you all so far for your responses.
I tried running it briefly with the accessory belt off and the sounds are still present.
Could it be spun bearings?
