2003 Sub Forester with loud engine noise-knocking. Dealer cannot find problem. Any suggestions?

Question

I have taken the car in for all its' scheduled maintanance like clockwork, and I use the recommended fuel. The dealer has actually gone over the car during my last two scheduled visits and cannot find anything that is causing the problem. The sound seems to be getting louder, and the car sometimes sounds as if it is going to stall. They have replaced the air filter and belts etc. They have put the car on the computer. The car has been taken out and driven by 2 of the mechanics. They have assured me the car is fine, but I just have this thought of having engine problems in the back of my mind. I have had really excellent luck with Subaru vehicles in the past, my last one had over 180,000 miles on it before I had to have any major repairs done. Can anyone give me any ideas what to do next. Would taking it in to a different Subaru dealer make any difference? I do know that engine noise tends to be louder in this model of vehicle. The noise is not affecting the performance. Thanks

Answer 1

Is it a rattle or an engine knock? With a Subaru, I'd say it's more of a rattle. Could be a heat sheild on the exhaust or the cat. convert. 2.5 is a very good engine and I'm surprised you had to have any major work done on the last one at 180K (probably the 2.2 if it was an older model). It is an all aluminum engine with cast iron sleeves in the cylinders. Made to survive longer than the driver. Lifetime corrosion free guarantee on the chassis. The only thing you have to do to these is to change the fluids, filters, and timing belt or belts.
