October 19, 200619 yr 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

I've read here in past posts that these can often make noises, especially when cold, similar to "piston slap". Just a guess.
October 19, 200619 yr Sorry.. someone's gotta' say it... Did you put diesel in it? but serioiusly, i'd check the timeing belt tensioner.
October 19, 200619 yr Author Sorry.. someone's gotta' say it...Did you put diesel in it? but serioiusly, i'd check the timeing belt tensioner. =) someone said I'd get better mileage? (kidding) How do I check the tensioner? and .. uh.. where is it? I'm new to this whole internal combusting engine thingy.
October 19, 200619 yr Just go to the ford dealer and buy a couple Powerstroke decals and stick them on your Sooobaru.... That should solve the problem.

It's under the black center cover on the front of the engine Open the article link on this page http://endwrench.com/main.php?smPID=PHP::article_detail.php&&RECID=184
October 19, 200619 yr Author 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?
October 19, 200619 yr If the tensioner fails it is often a fatal blow to an engine like yours. Sooner would be good.
October 19, 200619 yr my car did the same noise...and it turned out to be an idler gear...blew up 2 weeks later..... my g/f's impreza does that noise and its been going for a month or two with no problems yet
