advice please. x5 m54 problems

[ake53]

hello everyone, I'm looking for your advice. My x5 is at the point where it has a ton of problems. Its almost at the 100k mark soon.

-oil filter housing leak. -pissing oil. A LOT OF OIL.

-CCV doesnt work. -yellow sludge in cap and in dip stick. Heating engine snit enough.

-Belts need replacing. seen some cracks today.
---------------------------------------------------------------------------

As I attempted to do the gasket this morning, I learned without the special tool. I will never take apart the clutch Fan. So I put everything back and drove it. Still has oil leak problems.
--------------------------------------------------------------------------Talked to a few trusted car business people. They told me the job is way to much to do, and will be very expensive.
Even said to consider swapping the motor...?!
-others said to put the car on the auction. loose money and buy JAP car. -_-
-dealer offered me 6.5k as trade in for my 02 X5 3.0 94k miles. low..
--------------------------------------------------------------------------
Now I will ask my indy to give me a quote and advice on what to repair. If its to expensive.. I will do the repairs on my own when I have time. And buy tools and parts needed.
--------------------------------------------------------------------------
Finally question... What do you think? What else should I repair/replace since half my engine will be apart.

Thank you
