98 outback timing belt inquiries...
Ok. so I'm working on my friend's 98 subaru outback legacy wagon with the 2.5 DOHC motor with an automatic trans.
A couple of years ago, we pulled this motor and put new headgaskets on it as well as a water pump and timing chain. What we did NOT do at the time was to replace any of the idler pullies or tensioner. Of course, while we were at it, we did the plugs and wires since they are such a bitch to get to. So, we got it all back together and up and running. THEN, fast forward to 6 months later... He's running down the highway in the fast lane and all of the sudden the car dies. He coasts to the shoulder and tries to restart. It stumbles but will not start. Then, the car gets towed to his house, sits a year, and now I'm finally getting back to working on it.
So I checked for fuel and spark and both and they both seem up to par. I was starting to wonder what was next when I thought to check the timing belt. So I pulled off the outside shrouds ( I have yet to pull the center one because I need to get the crank pulley off) and found a few things . 1st. The timing belt has been rubbing against something and was shedding off from the front of the car side of the belt (it is now thinner). 2nd. the timing marks on the drivers side bank are no longer lined up. I am getting ready to pull the crank pulley and get a more detailed look at all 4 cam pulleys and crank pulley marks for comparison.
1. The timing belt did slip. But only a bit (as the marks aren't to terribly off) and this is an interference engine, isn't it reasonable to assume that the engine will probably be ok once I get a new timing belt on and lined up? Maybe thats wishful thinking.
2. If the outcome is promising, this time I am going to get a full timing belt, tensioner, idler pulley kit and do it up right. Does anyone have any recommendations on the best quality kit per the best price?
3. What could have caused this belt to rub itself narrower? Is this a common occurence? The belt is obviously narrower than the cam sprockets yet it is guided by the crank pulley so once turning, it should line up with that pulley and stay in a correlating position on all of the other sprockets. Does this 'ring any bells' for anyone out there? Maybe I have missed something here?
