I am in the middle of replacing both these items crankcase filter and EGR valve. I can't seem to get the filter off as its deep in the V. I have removed the fuel pipes, but there are 2 obstacles. The first is a thick solid pipe attached to the bottom of the valve and goes below the turbo and the second is a thinner pipe that seems to feed oil to the turbo.

Do I need to remove the turbo to get access to the filter and do I need to replace the turbo gaskets. Is there any thing I need to be aware of.

Thanks.
