NCDriver1 those are only the solenoids. Its recommended that all 6 be changed if you replace 2 that come in a pack. That's the best price I've seen on those though. I'm gonna pull the valve cover maybe this weekend and ohm mine all out and see if there any odd ones. By the time those are bought and new harnesses its over a grand if I do the work myself. If its actually an actuator those are really expensive new. Here is a set used for 400 bucks.
my cat c 13 kcb , 2007, 1798000 miles ,only put a new cylinderhead on ,and still running good ,no rebuild yet
Not really ignorance. Just more costly to maintain. Cheaper to convert it to single and not breakdown as much.
