This is how my Fzj80 engine sounds with 186k miles. The Fzj80 6-Cylinder motors are amazing. They are built of steel block (NOT ALUMINUM), which is great for water crossings!. The engine does not shake at all!!
Dude, strap that battery down!!!! No zip ties!!! You hit any large bumps and you will have leakage and broken post. I've seen it happen. Interstate battery, $250.00 Good Strap, $30.00
