OK, so update time,
Bought new Bremi spark plug wires and they helped the starts for a couple days but the misfiring symptoms are still there but not as bad as before, the worst is on hot starts.

Oil loss was due to using wrong oil(5w-30), switched to 15-40 Rotella and the oil consumption is now gone

New Behr fan clutch has been ordered and should be installed later this weekend, does anybody sell the MB lock rod tool?

While I'm doing the fan clutch might as well do the power steering filter, new drive belt and coolant flush.
What type of coolant is recommended?
