Question - 2002 Montero Sport XLS - 1/2/2007 3:38:14 PM    nashje   Posts: 7 Joined: 1/2/2007 Status: offline Hello all!!! I'm new to this site and have a situation with my Montero Sport.  Yesturday, while driving, all of a sudden, a horrible noise came from the engine.  Shortly after the noise the vehicle basically killed and coasted to the side of the road.  I opened the hood and attempted to statrt it again.  After starting the noise almost sounded like a belt flapping yet I didn't have any broken belts and it was behaving like it was misfiring/very rough idle and white smoke was coming from the exaust.   Any ideas on what I may be up against?  Any help is greatly appreaciated _____________________________ 2002 Montero Sport XLS Post #: 1

If the timing did go off, is your engine an interference engine?  Not sure which engine came with the XLS sport.  Which engine do you have? If it's an interference engine, then hopefully you were able to shut if off quickly enough that nothing was damaged.  The things that go bad are the valves, pistons, and head and related components (Because the timing belt prevents the valves from hitting the pistons). If it's not an interference engine, then you have no worries about valve damage when the timing belt goes out. If you need to replace your belt, you will essentially have to remove EVERYTHING from the front of the engine (all belts, pulleys, etc.) or if possible pivot/move them out of the way to allow access to the plastic cover that protects your timing belt.  Remove the timing belt cover.  Replace the belt and ensure timing marks are lined up. Re-assemble.  If you have to do the belt, you may as well R&R your water pump, tensioner pulley, pulley bearings, etc.  Depending on mileage and age of your radiator and whether or not you use tap or distilled water with your coolant you may want also want to consider rodding your radiator as a preventative measure to overheating your engine.

RE: Question - 2002 Montero Sport XLS - 1/2/2007 9:14:17 PM    nashje   Posts: 7 Joined: 1/2/2007 Status: offline It has a SOHC 3.5L v6.  I spoke to the mechanic since my last post.  He hasn't really looked at it yet and after starting it for a moment, he thinks the last place I had change the oil overfilled the oil.  He suspects they didn't drain the old oil by mistake and added 5 quarts since the specs say it takes 5 quarts.  What damage can come from that scenerio if driven for ~3000 miles? _____________________________ 2002 Montero Sport XLS (in reply to off roader) Post #: 10
