Cheers for that taff I am busy at home this weekend but maybe we could hook up in the future to sort these monsters out I am definitely going towards the stuck vanes in the turbo the reason for this in my way of thinking the turbo used to overboost until i fixed the vacuum leak on the swirl diaphragm (which was in that condition for a long time and a lot of miles)ever since i fixed the vacuum leak i have had this problem so I am thinking that once vacuum was applied the vanes were stuck in a mid position and have stayed there ever since,now to find a way to unstick those vanes

You may be able to get some long nose pliers on the shaft of the actuator and move back and forth while applying WD40. I did strip down an old turbo to see how it all worked.

Isit best to get at it from below,it seems quite inaccessable to me,when i looked at it the other day the shaft seemed clean but I guess i cant see whats going on inside the turbo i just hope it is this and i can get back to full power as i have been a long time without itThanks for all the comments guys as i have said before without this forum the car would have been baled a long time ago

I changed my turbo in January was not to bad a job but needs to be on a ramp.

I took some pics of the turbo insides, I changed the turbo as the actuator rod was sort of detached from the valve at the end where the vac pipe goes.
