yup i have the head cover off, and removed the broken spring. was just trying to get my parts list together and wanted to make sure i didn’t need to add a bunch of things to it. Cyl one returned very little after doing the test again with more pressure put into it. I think it’s due to the fact that there’s a much smaller space for air to go since the piston is at tdc. starting at zero and firing up the compressor it builds pressure nearly as quickly as when an air tool is attached to the line.
there’s a slight hiss coming from back near the crankshaft area which i assume is just air seeping past the rings. it did it on all cylinders

after putting more pressure in and confirming air returned on cylinder one numerous times i think it’s worth a shot putting new springs in and trying to fire it up, and maybe it was just an ecu error causing cylinder one to not fire. I could be wrong, but i could be right. Only one way to find out.

The fact that the dealership only mentioned a valve being stuck open on one cylinder also leaves me to believe that they didn’t really find any other issues, but i’m gonna give them a call tomorrow and ask just to double check.
