hello. I have a 2005 Ford Sport Trac with the 4.0. A little over a year ago I had all the timing chains replaced because they guides were wore out. A couple of months ago the truck died on my son. Towed it home and to my mechanic. The left side timing chain had broken. Replaced it . checked over everything to check for issues. All looked good. Thinking maybe got a defective timing chain. The other day I noticed that the engine
had a slight "tick" on the left side while running. Pulled the valve cover off and saw that the timing chain - which I just replaced not even two months ago - had a couple bro***** *****nks. What would cause this chain to keep breaking?
JA: Where exactly do you think the noise is coming from? And how long has this been going on?
Customer: The bro***** *****nks are hitting the valve cover and guides while the engine is running. Got some plastic shavings in the galley on that side. Just noticed it when I changed the oil the other day. Its my sons truck so I don't drive it much
JA: What is the model of your '05 Ford?
Customer: Sport Trac
JA: Are you fixing your vehicle yourself? What have you tried so far?
Customer: I do 98% of my own work. Had my mechanic do the timing chains because I don't have the specialized tools needed to replace them
JA: Anything else you want the mechanic to know before I connect you?
Customer: Like I said - I had ALL of the timing chains replaced a little over a year ago. And then the left side replaced AGAIN a couple of months ago
