MDS PLUG POPPER

MDS PLUG POPPER
Some of the late model Gen 3 hemi engines have plastic plugs in place where the MDS solenoids locate in the valley. They need to come out for block cleaning. They can be stubborn or even break when trying to remove. There is a small oil port near the lifter bores that goes directly to these solenoid plugs. If you pressurize this port with a rubber tip blow gun, while prying up on the plastic plugs, they will pop right out. Stay clear because they will fire out like a bullet.
