Ok my turbo has started making a right noise, a REALLY load wooooooooooooooo gets higher pitched as the turbo spins up and lower pitched as it spins down, but still VERY loud.

also seems to take ages to come onto boost too, normally picks a good boost up it 16-1700 RPMs now taking to over 2100 to get anything out of it.

I suspected a pipe had split on the intake system somewhere, but a cursory look round and they all seem ok.

the intake seems a little oilyer than normal too. although this could be build up as I haven't cleaned it for a while!

so, thoughts chaps?? is my turbo ********ed??
