2002 Boxster engine knocking noise.

[AkiRofe]

Hi every one second post here and hope everyone is well!

As per my previous post: I am from Sydney and have just bought a 2002 Boxster (FYI dark blue with cream leather <3 - as I failed to attach a photo to this post using my iPhone as it gave a JPEG thingy error message - please help?) - why I didn't acquire this wonderful thing before and wasted my time with other cars I don't know!

Just one day after purchasing the car (for a very good price so I want to fix rather than return it), I noticed an engine knocking noise.

The noise also get louder as the car warm up.

And, accidentally I found that after being tilted to get on a tow truck, the noise was gone for a day with normal driving, but then back on again - oil level related...?

A Porsche dealer's technician listened quickly and say it could be "hydraulic lifters (tappet), exhaust leek, external drive pulleys. The infamous IMS problem doesn't have knocking noise", and said that I need to book the car in when they have vacancy in 21th this month August for a proper diagnosis.

Could you please help me:

1. Is it true that the infamous IMS problem doesn't have a knocking noise?

2. In each case of tappets/exhause leak/pulleys: What would it be if I want to save for now and really need the car all times and not having the car fixxed but continue to drive it? Would it worsen any other parts and how much affect on performence?

Thank you very much guys!!!!!
