As far as the timing chain rattle I have read up on it and the explorer didnt seem to be making any of the noises described so im not too worried about that.
Wow, wish I seen this earlier.
Did this swap 99 ranger 3.0 to 4.0 Sohc
4.0 had 100000 miles on it, did the swap and dam if it didnt rattle.
So replaced all the chains, guides and all 2 months ago or less.
last several weeks was hearing a tick, investigated today and removed valve cover. Rear guide bolt broke and top of guide center top broke. This is not on tensioner side but opposite. I can honestly say this truck is great and with SCT custom tuned. Its a power house. This engine will be come out soon and 5.0 is going in.
Love the motor power but it's the worst mistake I ever have made. 3500 total ytd
