I have an 05 2.3 5-speed. Just yesterday at around 183k miles I noticed a knock relative to engine speed. It does not knock under load or at idle, it only knocks at very little throttle like when there is no vacuum or load. Oil was at the min mark on the dipstick (leaks alot) so I think it is rod knock.
generally when this happens on a vehicle with hi miles I pull the pan and replace the rod bearings to get by for a while.
I have been told it is unrebuildable and so far noone can sell me a rod bearing set. Does any one know why this is, or know where to get the bearings.
It still runs strong I just need it to get to about 230k or so. I am also annoyed that I wont be able to rebuild it myself and have to buy the complete short block (at rediculous cost)
Any help would be appreciated
