Ok. Should I do a leak down test first?

It doesn't really matter you can if you want. But you have to pull the plugs to do a leak down test so it'snnice to just take a quick peak first. That way if you see something major you can save yourself the time of doing the leak down test

Where are you located?

[mark4g63t]

Eden Prairie. Plugs are already out from compression test.

[asshanson]

With zero compression I'm going to guess a bent valve. Any broken springs? At this point you pretty much have to take off the head anyway.

[mark4g63t]

No broken springs from what I saw at a quick glance.

[goodhart]

Just take the head off.

[mark4g63t]

Will most likely start doing that tonight.
