Hey DOC
Great write up
Have a question about the spark plug tube. The left rear cylinder head is coated with some oil blow by. I was told by the Dealer during my PPI that the spark plug tube needs to be changed? Is this hard to do or is it as easy a pulling the old one off and sliding the new one in. Also should I replace all of them or just the one that is leaking? Lastly do I need special assembly lube?
Thanks
