996 Turbo Wategate Check

[Boggie]

Hi All,

Please can somebody tell me; should I be able to manually open 996 turbo wastegate by turning the lever on the outside of the turbo housing, even with the actuator lever attached? I am recommissioing the car after some years in storage, and want to check the wastegate operation.

Thanks,
B

Actually, I have found the answer! I needed to check it was OK to do this, before applying any force. So, if anyone finds this thread after wanting to check their wastegate is not siezed:

The wastegate actuators Push the rod, rather than Pull. There are a number of videos that show this in 996TT actuator tests. So, I used a pry bar to carefully open and close each wastegate. The RH lever moved cleanly, from closed to open and back with a good snap close. The LH lever was initially a little less smooth, and seemed to catch slightly, before closing fully. However, application of a little penertating oil and a number of times moving the lever through its full movement seems to have resolved this, and now it is as smooth as its partner.

Phew! The levers are a llittle rusty and seemed very hard to move, so I was worried they might be siezed. Turns out that the closure springs are quite strong, and a screwdriver is not enough to move them.
