Well I just bought a 1996 Subaru Legacy Outback 2.5L. I was doing some maintenance/upgrades. Changed PCV valve, K&N air filter, fuel filter, injector cleaner, spark plugs and wires, and oil change. I have no knoledge of the type of oil previously used. I used Valvoline 5W-30 Full Synthetic SynPower. I have heard about cars that swith to a synthetic oil at high milage can have a problem with leaking. Has anyone ran into this problem? My car currently just hit 115,000 miles.
Also the air intake went from the engine bay out into the fender, then goose necked down and back up into the engine bay there it ended. I basicly removed everything so that the intake ends right before the filter housing. It matches up with the first hole going into the fender. I then closed off the second hole going to from the engine bay to the fender. By doing this I increased the intake diameter as well as I should be cutting down on the ammount of warm air I intake. Has anyone else ever messed with? I have noticed a slight noise difference, but not much at all.
I am also looking for similar type things, cheep and easy upgrades, to mabye increase a little hp and run the car as best as possible. Any other ideas that anyone has, I'd love to hear them.
