Misfires and flashing CEL

[Stl-986]

Dont forget to lock the cams!

I almost have all the bolts off the cam cover. it’s a bit of a squeeze. i pulled off the scavenge pump and so far things are looking neat and clean inside, but the real telling part is yet to come

I got the cam cover off and i’m not going to lie, it looks perfect in there. it’s got 124k so there’s a little bit of wear marks on the cams and lifters but nothing catastrophic. no metal in the oil. from what i can see of the lifters everything looks okay.

What are your thoughts? I’m leaning towards a broken spring at this point. Just as a recap the dealership said they could see one valve stuck open on what i’m assuming is cyl two, since that’s the one with zero compression. When i took the header off though it was very obvious cylinder one wasn’t firing either.
