I parked my truck for about 2 days and it was fine when I parked it but when I fired it up it had this tick or knocking sounds, wanted to see if anyone else had the same problem. We think it's the timing chain since I got a bunch of misfire codes but any extra info would be a great help, thanks.
Techron is available in shops and frequently goes on sale here in the US. Many people swear it's an effective cleaner.
Add it before a stint of local driving because it works upon shutdown.
FYI: Also, many will say your gas filter is overdue for replacement since you're at 185Kkm / 116K miles, but that wouldn't create a misfire/knock/tick condition overnight.
After you chase down your condition be aware that the oxygen sensors and timing chain tensioners are 160Kkm / 100K mile replacement items.
These are "Crossing the T's and dotting the I's things" to be done soon after you address your current problems.
