Been getting a knocking sound from my car so today i decided to take the sump off again and have a look. Took the baffel plate off so that i could see my crank and connecting rods. I have play in every connecting rod from side to side??? is this normal????? there seems to be no up and down play. How can i check the shels to see if they are okay is there anything i can use to check the gap?? and one last question, how are you suppose to take the chain off the oil pump.
