Re: Valves are stuck open!
I heard somewhere that ATF has good cleaning properties. Someone wrote that their lifters were sticking and someone said to try using the ATF. I think the other solution was to use Marvel Mystery Oil.
If the valves are sticking open, perhaps you could remove the valve cover and pour either the ATF or the Marvel Oil over the valve springs and stems where they go into the valve guides. Let it set for awhile to soak in and see if they close. Maybe things are alittle gummed up.
I have never used either of these products for this purpose so I cannot recommend you do this. I am only telling you what I have heard from other people.
If you go this route, especially with the ATF, I would definetly drain the oilpan and change the oil before starting the engine.
I think the Marvel Mystery oil is an oil additive so read the instructions.
