oh man, I took it all apart; I was able to do it without completely removing the radiator. but anyways, took it apart and man, my chain is completely jacked. its got about an 1" or more of play. how does this happen? its only got 150,000 on it. I thought chains were supposed to last for wayy longer.
also, theres a spot on the cover that looks like two little tabs for a tensioner or something? is this used on the 4.2? cause they're pretty much gone on my cover.
