So… I had just fixed an exhaust leak on the mid muffler on my 99 LC100 1HD FTE and upon complete started to hear other unfamiliar noises. The noise in question sounds like something metal on metal spinning. The sounds isn’t apparent at idle and happens from about 750-2000rpm under load, with no load the noise is absent.
Things ive checked:
Pulleys - idler, AC, Power heater, alternator, water pump, main pulley(still bonded/not wobbling or contacting timing cover) timing belt, injection pump, cam and timing belt tension pulley.
Don’t think this is related but, the fuel pick up line had pinholes near the fuel tank this was causing long starts Replaced a section of the hardline with some high performance stainless braided lines, replaced the primer pump assembly(pump wasn’t stiffening up) fuel filter, and fuel water sensor and gaskets.
Oil changed 2000km ago, transmission fluid drained and filled 500km ago. New air filter 500km ago.
I’ve stethoscoped block, head, injectors, pump, timing cover transmission injector lines, accessories - ps/ac/ph/wp/alternator with no luck tracking down this noise
I’m starting to thing possibly flex plate issue. I’ve read that there are no sight holes and can be accessed thru on of the bolt holes. Will dive into this in a few days, maybe in the mean times someone has hear this noise. Will attach a video.
Thanks
