Did you ever solve this problem. I would be interested in the solution. Thanks!

4.0 OHVs are known for carbon issues that can lead to; spark ping (from increase in comp ratio), ticking (from piston contact with deposits in quenche zones), buzzing and rattleing (from carbon loose in the exhaust sys) First I'de recommend getting a good combustion chamber decarb additive from the local autoparts store, and run with that for starters. Can't promise this coarse of action will cure it, but the next option is a bit riskier! In alot of exsteme cases the deposits are so tough that it can take flooding the chambers with special solvents or blasting them with ingested shots of water, :nono: but if this isn't done carefully you can hydro-lock the engine! :2cents: You may want to have a shop that offers induction and de-carb services perform that chore if my first sugestion doesn't help.
