This thread needs to be updated!
The 4Runner had an engine had a knock coming from #2 cylinder. The knock would come and go then in 2012 the knock wouldn't go away. I bought a 1988 750 Ninja and road that for the summer saying to myself that I would rebuild the engine in October. In November 2012 I bought a 04 Harley Road King and didn't do anything to the 4Runner except drive it around town once a month to keep the seals from drying out with the engine knocking. November 2013 I put 5 gallons Chevron gas and was driving it around town and noticed that the engine knock was getting quieter the more I drove it. I filled the tank with Cheveron and I drove it around town everyday for a week and the engine knock went away!
I've been driving it ever since as my daily driver again
I have a new list of mods I want to do
