I'm sure that is why i've killed 2 turbos.
I've had a look in the Haynes book... it looks like to get to the oil pump i need to remove the sump. That is ok for me, i've already changed it so i know what to do there.... although i can see a small problem...... sump off = no oil = very very low oil pressure
So can anyone help? Where do you check the pressure with the sump still on.
