I have a 2002 wrx wagaon. (my wives car and long overdue for a timing belt change 150,000) I purchased a timing belt kit and I am about to embark on the task of installing it. The kit came with camshaft seals and my question is should I replace those while doing the project? Most of the tutorials I have read either don't cover this or are very vague. The subi looses oil between changes though I am unsure whether cam seals are the cause; However, I was wondering if i should go ahead and replace the seals since I will be so close...But is this gonna be a TASK?...that may not be necessary? I will appreciate all advice given, though I am a nube so please don't be vague.
