I have a 2013 and removed the head. You have a few components that need to be removed first. Intake manifold, timing chain, fuel injector rail and some wiring harness brackets. I did leave the exhaust manifold attached, disconnecting the 3 bolt flange to the catalytic converter. I had a broken timing chain guide and knew it was likely that I had valve damage. Here's what I got now...lol

Thank you....I cleaned it. It is direct injected and it had heavy carbon buildup. Brakeclean, degreaser and scotch Brite pads cleaned it up pretty well..

had you been using DI cleaner before the tare-down ? Im about to spray the intake to clean the intake valves, i do add Lucas every 3rd tank ,5-6oz,,,Im at 69k have done one trans drain and refill,,it came out like black water.. After doing trans it is shifting better. after i spray intakes ill change plugs...I have been lucky mine doesnt use a drop of oil between oil changes

I didn't use any DI cleaner on a regular basis. I wasn't aware of the amount of carbon buildup until I removed the intake manifold. A leak down test confirmed compression loss in cylinder one. After removing the head and cleaning it, I removed the rockers, springs and valves. I replaced all 8 exhaust valves, they were pretty bad. I then ported and polished the intake and exhaust ports and combustion chambers. I lapped the valves which went okay, but I still had leakage in cylinder one. I am trying my best to not go to a machine shop. I ordered 4 new intake valves which should be here tomorrow. In the meantime I pulled the CAT, and removed the waterpump & thermostat to install new ones. Hopefully the new intake valves will seat correctly and I can start putting everything back together.

did you lap them in ,,with course then fine compound ? how did your timing chain and guides look ?? how much work are in looking at to pull the intake manifold to inspect my cleaning job ? im 63 with a bad back so a 2-3 hour job can take alot longer lol

Lol....your timetable sounds like mine...Yes, I've lapped them in. The paste I bought is multi-grit...add a couple drops of water in....I've had some valves still leaking slightly, so that's slowed my down. Think I've almost got them...just a couple exhaust valves slow dripping... they're brand new, so I think more lapping should seat them. Then...into installing the springs and keepers...haha ...ya

Pulling the intake isn't bad, If I remember I think you just have to pull the throttle body first. It's plastic so it's not heavy like the exhaust.

tap them lightly with a plastic head hammer,,its like them running,,,you can use permanent marker and snap them shut with your hands without springs to see the pattern to
