I've always used water from a spray bottle to clean the combustion chamber if its a carbon issue in the cyl.
TO CLEAN OIL AND CARBON BUILD UP TRY AN INJECTION CLEANER. SEAFOAM WORKS WELL AND IS SOLD AT MOST PARTS HOUSES. IT WILL ONLY TO CLEAN ALITTLE BUT ITS A GOOD START
thanks pretty much I need it clean enough to pass emissions without having to pull the engine apart
I think you mean oil is ponding in the spark plug tubes, if so this requires installition of valve cover gaskets with spark plug tube seals! Also a mechanic to do so. Pretty tough job for a DIY!! Or an experenced tech. for that matter.
its mainly just an emissions issue thankfully I don't believe it has gotten that bad
the battery gave up before it could
Where do you see this "backed up oil" inside the cylinder after removing spark plugs? Or on the spark plug boot before removing plugs?
