Sweet EB Member 27 Member For: 19y 16d Gender: Male Posted 09/02/14 07:04 AM Share Posted 09/02/14 07:04 AM (edited) Hi All, I have a failed wastegate actuator (perforated diaphragm) causing overboost issues.I am just replacing the actuator with another new standard one.I have read that you can replace this with the turbo still on the car. I have looked over this and had an attempt and I simply can't see how you can disconnect the actuator at the wastegate end let alone reattaching the new one with a new circlip..I have used a mirror to have a look and without being able to really see what I am doing along with only just being able to feel what I am doing I can't see how this is possible.Anyways, I have decided that I am going to remove the turbo instead to do the job. I have taken all the heat shielding off and taken all the nuts off that join the dump pipe to the exhaust housing but it doesn't appear that the dump pip has enough room to slide backwards off the studs and I am going to have to pull the turbo off with the dump pipe attached (no biggy)..If I remove the oil return line at both ends, will I be able to access the bottom front turbo to manifold nut with a socket and small extension??Any tips would be good. This initially appeared to be a fairly easy job but is turning out to be a pain in the arse... I was wondering if there is an easy way??? Surly tuners are not having to take the turbo off to fit a higher rating actuator so there must be a trick.???Any help would be appreciated..PS car is a BA mk1 xr6 turbo with all standard hardware.

Mine was tricky too. Once I loosened the dump I could get to the circlip easier and then you will need to work out how to remove the circlip you will home and hosed.

Sweet EB Member 27 Member For: 19y 16d Gender: Male Posted 16/02/14 09:12 AM Author Share Posted 16/02/14 09:12 AM (edited) Ok, Just finished the job. Ended up taking the turbo and exhaust manifold off. I have the support bracket so I had to take the turbo off the manifold as well as taking the exhaust manifold off. I separated the exhaust at the exhaust to dump pipe flange.I took too long trying to replace the actuator with the turbo in situ. I can't see how this can be done. Once I took the turbo off and had a look, you would have to be some kind if magician to be able to do this job with the turbo in place. The little clip holding the actuator shaft to the wastegate is sooo hard to get to. It was also totally destroyed once I had removed it. It wouldn't stay on with any confidence when I tried to re-use it. I ended up using just a conventional E clip when I put the new actuator on.Anyways, if you are thinking of attempting this job then be prepared to just take the manifold off as well as the turbo. It makes thing 10000% easier. The bottom front turbo to manifold nut can be removed easily by using a 1/4 inch drive 14mm socked on the end of a fairly lengthy extension. In all honesty, with this combination it was the easiest nut/stud to get out. All but 1 of mine had the whole stud come out with the nut attached. No easier or harder to remove/replace.Whole job was a little fiddly but definitely not hard. Be patient and most with a little mechanical savvy will do this job with ease.
