Gummy rings is there a cure

[SKINY]

Obviously the cure is open it up and change them lol
But, is there anything else that you can do ? An additive or anything
Was sat for maybe an hour earlier and had the occasional puff, nothing major like Puff the magic dragon on the like lol
After compression test(in my thread) it's down the same psi on all 4 cylinders

Stick some seafoam or similar down the plugholes and leave it to soak. That might help if you are lucky

No magic cures.

Would need stripped and cleaned IMO.

Must test it again see what it's at, pulled well as per yesterday

 

[SKINY]

I see the seafoam but haven't looked into it yet

Leak down test is what you need.

The engine will still boost, it's just those gummed up rings will pressurize the oil system and could also promote bore wear.
