The problem with this is the inlet valves clog up due to no fuel going passed them.

The heads have to come off to clean the valves if the intake cleaner spray fails to work.

The only way to avoid this is to use an intake cleaner like wynns direct injection intake cleaner at every 10k service.

@billayles intake valves dont get clocked from no fuel going passed them. what about diesel engines diesel engines use direct injection to. no fuel goes passed their valves. The only thing that could clog the intake system might be egr (exaust gas recirculation) but engines run cleant these days thats even un-likly

"electromagnetic combustion valves" ... so they're not piezolectric injectors??

Already wow i dint think it was going to happen for a while.But i knew it would becouse of how good it worked for diesel engines.
