engine knock? - YouTube

i asked this already and people said its the rod bearing but i think its the lifters i took the engine out put it on a stand and notice my fly wheel bolst were lose like really loose and it moved up and down since i used bolt tight green which makes sense why it sounds like death... now the rods r tight and compared to what i seen before when rod knock occurs there is no play i cant move them at all also my oil pick up was full of mud like sludge and i pulled 8.3 oz of sludge from the bottom of the pan which could be why the lifters werent getting enough oil... how do i know if i have rod knock now that the engine is out on a stand....

Look for metal pieces in the bottom of your oil pan, check and see if rods have play (up and down) on the bottom end that's what I found when I had a knock which was a spun bearing.

If the motor is out and you are going to be wigling the rods around why not just remove the rod cap on each rod and check.Real easy to see a spun bearing because the crank and rod will Prob be blue/black to start and will be tons of crap in the pan

Also check the balance shaft bearings if it has them in it

i bet it spun o bearing esp since you said you pulled sludge from the pick-up. not only was your lifters not getting oil but nothing else was either
