Essentially whats happening is the exup valve is binding to the point its preventing the exup servo from moving the valve. And as a lot of fellow thou owners will tell you -
- Cant stress this ENOUGH, always always ALWAYS!, spray copious amounts of quality penetrating fluid (not wd40) on the 3x m6*10mm allen bolts that hold the valve cover on and leave over night if you can. The absolute LAST thing you want to do is snap one of those off in the exhaust headers as its a fucking right pita to drill them out if you dont have acess to an overhead drill machine - Most owners replace these shitty mild steel bolts with high quality stainless or better titanium bolts.
- You will have some wear to the valve shaft ends will already have happened, but its not the end of the world.
- once you have the valve out, check for true - my simple driveway trick is to put one end on a variable speed hand drill and rotate to check, if its out wack it with a rubber mallet. Thenroad the valve so you insert the other end in the drill - rinse and repeat untill you have a nice straight exup valve.
- And lastly create a calendar reminder to lube the valve and the bolts with copper-ease every 3 months - it takes about 15min.
