Critical - Maintain your Turbo Actuators

Is there any kind of grease or lubricant that will withstand 1000 deg C? Because that's how hot the turbine can get. I haven't heard of one. A problem with binding wastegates is caused by incorrect alignment or not actuating the turbos often enough. The first time you drive the car hard on boost for a while, anything you put on there to lubricate that hinge is going to become toast, literally. Drive the cars like they are meant to be driven, that's what Ferry said (or something like that ).

don't do anything to them except make sure you exercise them regularly...if 'lubricants' are helping, they are 'done'

1.3 is starting to push things. High boost is the other symptom of WG failure. The big difference with (un-controlled boosts is) that it could scatter your motor

Btw there are high temps lubes which are used in turbines. The lubes can exceed well over 1000 deg.

No one disagrees that the lubricant becomes "toast" at high temp. If you lube it so often when cold and not running, marvel will eat the corrosion from salt roads etc when sitting. This will allow the natural effect of the wastegates when running to be more free. The key is to keep the corrosion from hampering the metal hinge.

Just performed this service, 50k miles on the clock. Some points for anyone who reads this thread in the future (like I did)
- I used an anti-seize aerosol, high temperature (1,600 F; 870 C)
-- Loctite Silver Grade Anti Seize: https://www.tenaquip.com/product/loc...p-135541-ya275
- I was able to move both actuators by hand, slowly *pulling* them towards the rear of the car (there is strong tension, but I was able to slowly actuate them with my hand+thumb
- Access is fairly easy, I did not lift the car but did get a bit dirty on the floor
Spring punch-list items are nearly done!
