I stuck my bore scope in after the compression test, you can see valve collision marks on the crown of the piston. I'm pretty sure the chains are broke or worse.

I bought a running car for parts so I have a spare 2.7.

I just resealed the cam covers and installed plugs and tubes.
I'll do the IMS and RMS next week when it cools down here.
