Audi a4 Engine problem

Alanvtec

I have a 1.8T B6 quattro. I just bought the car like with a blown engine so we rebuilt engine but here is where the problem starts. We started the car and it ran perfect but when we took it for a spin in first and second gear there was no boost problem but half way in third (after about 10 secinds) it would loose boost and it sounded like it was trying to boost like this thread

but the oil warning light comes on the exact same time i loose boost. Also if you drive the car without the letting the turbo to kick in the oil warning does not come on. (I believe they are linked) and aswell we just figured out that the cam chain tensioner needs to be changed because it sounds exactly like this http://www.youtube.com/watch?v=toO2nP9UjDk



Is there anyway that all these are linked I have no clue whatto do. I am going to change the cam cahin tensioner but will this solve the boost problem

When you say you rebuilt the engine, what exactly was done? What was wrong with the engine beforehand?

Have you had the car scanned, what faults are logged?

The oil pump ran dry and it starved the head so I got the whole head rebuilt but changed nothing in the bottom end. when we put the diagnostics machine it only read the cam chain tensioner fault nothing to do with the oil light or the boost problem

Surely oil starvation would suggest the turbo is banjaxed too.

So the oil pickup was blocked and starved the head of oil, I'd also say the turbo is toast and the bottom end.
