Hi po mga sirs!

Just want to seek your advise. It seems that my car has leak from the power steering. Bale just yesterday i had oil change in Petron fairview. Just when it was brought up by the hydraulics, may nakita akong unusual na basa sa may left wheel/suspension. I touched it myself and it was oil. So i asked the mechanic if this was normal and he said baka may tagas nga yung power steering ko. He suggested that to isolate the problem i need to have an underwash, only then can they find out where the leak is coming from.

Anyway, hingi lang sana ako ng payo sainyo since i'm not very knowledgeable pagdating sa auto... just really basic stuff. Ano kaya ang maaring cause neto? Any experience you can share?

My car is a 95 galant VR4 by the way.

Hope to hear from you guys, thanks!!
