glen, how would you suggest to get sea foam to clean those valves? you just pour it into the intake manifold? i dont know how that would work.

Well, pretty sure seafoam will do squat
Picture a thick layer of grease that caked on the valves as well as intake tracks over time, and rubbing with a tooth brush won't do anything, but instead you have to blast away with a very abrasive material (enter crushed walnut shells), chemicals have little chance to work, unless you're pouring acid in ......
