Update:
2019 Jeep Grand Cherokee Head Gasket Repair
It's Thursday now..
Had a couple unexpected jobs pop in so got delayed a few days on the "Operation Jeep 3.6L Teardown"

Besides the timing chain and tensioner...
Got a few more bolts to remove and that head will lift out.
However... It's Almost apart.!
Exciting Stuff. WhooHoo 🙄 😁

Brand New OE Spark Plugs with some seriously different spark gaps... 043 is the targeted gap but that's not what I had for all 6 plugs. Tightest gap was .006 😬

This is a good example why you should ALWAYS check any new spark plugs prior to installing them.

These would have been installed under an intake manifold plenum which is a 2.6 hour job to do.
Sure would suck to do this job twice for a one time pay. 😜😤

I was hoping that TopDon would get something like this working.! Thanks Haakan Light for the demo
