My Toyota 2D truck has a knock sound that comes up and disappears when the truck is loaded and moving but its never there when the engine is idling. What could be the cause?

Excellent explanation, definitely my Toyota has a “fuel problem”, passed emissions test flawless (no codes)but under acceleration valve train rattle even using “93”, with the a/c on it’s even worse and also struggling to crank it up in the morning, my dilemma is finding what’s wrong, the fuel pump (hell of work) or the fuel regulator ( expensive part) ☹️

My Kawasaki GPZ 900 engine knocks rhythmically at 4000 rpm, as if a key were tapping the exhaust manifold. I replaced the tensioner and timing chain and it didn't help. Recently, I looked into the cylinders with a camera and the pistons 2 and 3 are covered with a layer of carbon. Do I suspect knocking combustion correctly?

What would cause a new motorcycle engine with only 1900 miles knock as it’s warming up, and stop knocking when it’s warmed up?

What if this engine has a little too much motor oil ?

[ronaldwilliams]
