cidion Posted October 19, 2006 Share Posted October 19, 2006 Hi folks. Often in the morning, if I let my wagon idle, there is a scraping, rubbing metal sound in time with RPMs. It makes my petrol car sound like a diesel. If I step on the gas, and step up the RPMs, the grinding goes away, and all sounds normal. After arriving at work (a 20min drive) i can idle, and there is no grinding. Some mornings, it's not there. Others it is. I can't tell it it's temperature related or not. I added some Rislone to the oil (as per my mechanic friends suggestion) and it didn't seem to help. Anything sound familiar about this? It's a 2000 OBW, 150K miles. Timing belts and water pump changed a little after 110K Thanks Bryan Link to comment Share on other sites More sharing options...

I've read here in past posts that these can often make noises, especially when cold, similar to "piston slap". Just a guess. Link to comment Share on other sites More sharing options...

Soutthpaw Posted October 19, 2006 Share Posted October 19, 2006 Just go to the ford dealer and buy a couple Powerstroke decals and stick them on your Sooobaru.... That should solve the problem. Link to comment Share on other sites More sharing options...

cidion Posted October 19, 2006 Author Share Posted October 19, 2006 Thanks for the quick replies. If this is a belt tensioner, should i get it fixed ASAP, or can i combine it with other work in the next couple of months. Will it do more damage to other things if not fixed soon?

cookie Posted October 19, 2006 Share Posted October 19, 2006 If the tensioner fails it is often a fatal blow to an engine like yours. Sooner would be good. Link to comment Share on other sites More sharing options...
