I'm going through testing everything in the vac system and found my charge control actuator is no good. It works fine on one side and will move when vac is applied + hold the vac no issues. But the other side when I apply pressure leaks very very badly to the point it won't move at all. Amazing the second turbo worked at all. In addition the solenoid had a decent leak. Pic shows where it leaks, if that matters. I'm gathering these can't be fixed. Does anyone know where I would get one from. I've spent an hour on google and can't seem to find a source. Also for the solenoid, I can see them on eBay at about $300AU. Is that good or is there a better option? I've seen some mention of using MAC solenoids. I'm in Australia so a local source would be preferable but not essential.

You would be better off buying a used solenoid rather than spending that kind of money for a new one. In a another thread, it was noted the "new" solenoids are somewhat of a gamble. Not worth the cost.

 

Try to hook up with MARCUS Read in Sydney.

 

You have an effectively infinite boost source to that port, vacuum is a different story. Have you actually had any performance problems on the car?

Second hand is likely to have similar wear. If anything disassemble and have a new shaft Bush turned up, if you are really excited you could get an internal Oring groove cut in it to seal in the shaft.

 

hmmm, that is a damn good point. The side that leaks is connected direct to the output of the second turbo, not via a solenoid. From the point of view of the turbo the leak is small. If I use something besides the hand pump then it will stay open. I think I'll consider that good. Thanks
