Changed my spark plugs this weekend on my 2.7L following the Panda Motorworks install video. Pretty straightforward. Had to buy a torque wrench that does 133 inch/ft torque (well 11 lb/ft).
Yeah with the famous Jeep 3.6 Pentastar, yoy have to pull a bunch of stuff off, including the actual Intake manafold just to change spark plugs.
I think stuff like that is what the OP is asking about. Some engines seem to be designed by people that have never had to do typical work/maintenance on their own vehicle.
Shouldn't have to loosen motor mount, or pull off alot to get to spark plugs people! Things like alternators and starters should be relatively easy to access, etc
When you install the Ronin Oil plug the first time there is a wave spring that goes on there .... I want to take the whole plug out to see if the magnet has caught any burrs .... do i need to change the wave spring?
