I had just gotten rolling down the interstate going about 70 mph when my truck started a loud clacking sound & the torque shot up, engine light came on and started loosing power.
I thought it might be a rod because of the knocking noise. The oil is clean with no signs of water so it didn't go through the block. The local mechanic says I need a new engine. I just got back from vacation & haven't talked to him so I don't know if he took off the valve cover to check the rods. If it's not the rods could it be the harmonic balancer?
Thanks for any help
