2017 No Compression Middle Cylinder

[Rick Chalut]

Hello

I have no compression in the middle cylinder. Haven’t had time to pull it apart yet. Anyone else drop a valve or blow a piston?

Also doesn’t anyone have the torque specs for the engine? Will also need to know the timing marks after I pull the head off if anyone has that info.

Thanks

Are you a VIP here? If so service manual has all that info. Can do a few checks to find what it is that's wrong before hand if you want. Use your compression tester hose to put a few psi of air in cylinder and listen where it comes out. Pressure test coolant system to check headgasket and easiest is bore scope to look at piston top and can see enough of valves to know if broke off through intake and exhaust. Ones that go to your phone are cheap and work well.

Become a VIP like CDale said, or risk being shunned like a step child with the Covid virus!

Besides it helps support the site, well worth the $$$$$$
