I have just bought myself a 01 forester a few days ago and between taking it to the mechanics for rego and doing oil change etc, I have started to uncover a growing list of things that need repairing. Front CV boot's have gone, I think the valve cover gaskets r leaking,as they are covered in oil. Today I noticed a loud tapping noise from engine, I think that means the tappets have nearly had it,am I correct there? Also today I found what looks like a leak coming from just above the thermostat, Does anyone know what that would be? Also wondering if it was normal that every time I do something like a oil change, or clean air filter and intake, the car runs like crap at first then the next time I take it for a drive it runs good again??? I am willing to spend a bit of time and money on it, but I don't want to be fixing one thing after another and end up rebuilding the whole car. It has 174,000 km on the clock. Any advice or feedback would be greatly appreciated. Starting to feel like I have bought a money pit and I don't have the money to rebuild everything on the car.
