i the enigne still runs but there is a knocking sounds which i believe its coming from the cylinder 1 which the bearing on the rod connecting to the crank is loose, just a lil. I removed the oil pand to check it out but from below i can tell all that much and im not sure what to look for. but the piston heads from the bottom look redish or looks like red marker lines idk. but the rods look fine. i want to find out but i dont want to have to tow it someplace and have to leave it there. or does anyone know someone i can call or a shop near me LA, CA (near 605 & 60 fwy)
