The first time I changed the oil filter I had no idea of the correct filter to buy so I removed it and got a similar sized one from super cheap! I think. Anyway this time round doing a filter change I bought a filter online specific to the ej20 and BG5 chassis. What I received was clearly way too small compared to the one fitted to my car. The filter fitted to car is about 83 mm diameter Not yet removed from car. The specified OEM filter is 15208AA100 replacing the original ...024: Which is about 68 mm dia. It has been suggested to me that an over-sized filter housing has been installed possible from a 6 cylinder Subaru. When I bought this car years ago now I was told the motor had been rebuilt by the 2nd best Subaru guy in NZ believe it or not and I took the mans word on that. Any how is this all possible? An over sized filter housing on original motor. Could there be some clever good reason for a larger oil filter maybe installed in the rebuild. Can anyone advise what oil filter I should be looking for as replacement, or no anything about what's happened here? ....

Thanks for that, hope you are right on the money, sounds not too expensive. Much appreciated.

Would that be drive shaft universal bearing?

I've recently bought a 96 legacy GTB Wagon Auto which is now making a brief hum/wine noise with moderate power on in 2nd to 3rd change up. I'm not sure if this is the auto trans or other part of drive train. Sounds like noise is coming from behind front seating. Any ideas would be appreciated. Could this be expensive! Cheers Legover
