Question about 2003 Subaru Outback
2003 Subaru Outback wagon w/ 2.5L 4 cylinder boxer engine sounds like a diesel all the time. Some sort of valve slap/tapping. Two dealers have told me that the boxer engines just makes that noise, but I have had an '02 Legacy wagon w/ a 1.5L four boxer and have an '07 Legacy sedan with a 2.5L four boxer engine, neither one of which makes/made that noise. Is there a cure for the noise?
Heavier oil if you are not in a cold climate. but before you do that have the oil pressure checked. We used to use a can of STP every once in a while on a motor in a dodge we had... nothing wrong with it... was just noisy.
