Ok, let's cut to the chase....upon removal of my downpipe (part of a mechanical overhaul/modding process), i found this....
Just what I didn't want to see, but i'm glad i found out now rather than it failing altogether and causing catastrophic engine/turbo failure.
A quick search revealed just a couple of threads that possibly suggest this isn't uncommon, especially for high mileage cars like mine having covered just short of 130K.
Any thoughts on possible causes for the cracks? I currently believe this is a combination of age, mileage and enthusiastic driving styles through the various owners. Is this a classic case of the engine/turbo not being warmed up and cooled down properly before or after being subject to hard driving?
On the plus side, my 3'' Relentless DP and 3'' Relentless de-cat pipe are now up for sale in classifieds - Monies will be going to a good cause....to replace my broken turbo
