Hi everyone,
I have no experience with turbos so I'm hoping someone will be able to advise me with my problem as I have no idea I have what sounds like either a grinding noise or a tin like exhaust blow (aggressive) coming from under the bonnet which starts around 1800rpm. and goes around 2500rpm. I've looked at EGR pipe and that seems ok (no splits). I've had a look around inlet manifold etc and all I can see soot wise is a bit on soot on top of turbo. I've removed air intake pipe and felt the centre shaft and this seems firm.
Looking at the photos I took I'm wondering if the impeller look ok to the trained eye? Does anyone think from looking at the photos that maybe the blades are hitting the sides when the turbos boosting as I'm not sure if it looks a bit scored in there around the outside.
Any advise is greatly appreciated
Here's some pics I took today
