There was a slight wistle from the turbo, and then sometimes when pegging it, a woosh of air can be heard - which I assumed to be the wastegate.
Anyway, given the good weather, and new facilities ( we've got a house with a drive
I found the turbo pipe FROM the turbo to the intercooer was very loose to the point of hardly being "inserted" into the turbo itself. I noticed the mounting bracket had the bolt missing from the plastic pipe to the engine, so pushed the pipe upwards into the metal flange of the turbo ( two o-ring seals were visible before, both now inside ), and found some cable ties to use as a temporary bolt before I can "borrow" some bolts from work tomorrow.
The difference in the refinement and performance of the car is amazing, the first time I pegged it, you should have seen the c**p out the back -
So, the moral of the story - don't assume, check !
