Heavy oil usage despite power test shows equal compression in all 8 and oil been changed timely. Dealership/3rd party mechanics all say the engine is fine and won't work on it.
What is your question?
Heavy oil usage (1-2 quarts per week) despite power test showing equal compression in all 8 and oil been changed timely. Plugs 2 & 4 need regular cleaning. Dealership/3rd party mechanics all say the engine is fine and won't work on it. Could vandalism cause this?

#2 "need regular cleaning"..... WHY? Can they explain that? Also , How many miles on engine? Valve seals ruled out? Why? ... How many miles in that 1-2 quarts per week?
