Hey guys, this is my first time posting i'm trying to figure out if i should buy a 92 legacy turbo wagon for work reason(window cleaning) i went to take a look at the car today, and the car seemed in reasonable shape the only thing that concerns me is when i was test driving it, i heard some type of metalic clicking noise from the front of the car. I know the owner just had the brakes fully replaced, so i'm pretty sure it isn't that... can anyone help me out with this... also when i release the handbrake the light is still on.. also another concern usually i would search all this up, b4 posting but i can't seem to get the damn search to work for me =( i came across a thread here relating to click'n noises in the EA82 engine, http://www.ultimatesubaru.org/forum/article.php?a=8 but i believe i have the Ej22t engine anyways i believe specs on the car are 2.2L, overhead cam, 16 valve multi-port fuel injected (please correct me if i'm wrong) if anyone has any links where i can find some information about this car and the engine that would be great... again i tried the search function and i wouldn't work for me .. so spare me plz thanks alot guys .. -ped
