At least the car is insured.

Some people just dont know when to give up and let go.

The car is a lemon, and unfortunately so is the owner.

From the shit off your other posts about the oil feed nut, id say its not the one pictured as that uses two banjo bolts.
A banjo bolt is a hollow bolt with holes in it to allow fluid to pass through it.

So, you could well have the wrong turbo fitted, and some prick has cut and shut the oil feed pipe to make the bodge fit.

But without anyone actually seeing the car in person its pretty difficult to make an informed decision over the internetz.

My advice, get rid of the car.
