Hey,
I posted a month ago about a ZD30 squeal while under load, took it to my mechanic, where he isolated it to the wastegate and recommended a full turbo recondition (from GCG Sydney for $1430). [Yes, I stupidly did this knowing a new turbo is 1550, it was my only option over christmas and I needed the car ASAP to get to northern QLD to start work...which is now flooded...rats].
Anyhow, now the squeal persists and I think it is actually worse. My mech says its hitting 6pound normal boost, and is really stumped on what it could be. Anymore ideas anyone? I read people have seen cracks in exhaust make a squeal noise...should I take it in for an exhaust check up? Can you get exhaust check ups?
Thanks heaps for advice.
