Awesome that you got it sorted! Code 66 sucks! Just check for vac leaks, clean out the boost solenoid in the passengers guard and check that the secondary bypass valve isn't leaking.
Pretty sure the bg5a's use all four blocks with lines 15 & 16 going to the secondary bypass valve nipple and the bypass valve bridge. What year/revision is your bg5? Will take some pics of my bg5 for you later this morning.
At an educated guess as the exact same thing happened to me plus I've seen it on a bunch of other subies. Rocker cover gaskets?
Mine didnt leave any spots on the ground either.
It tends to happen around the 150-200,000k mark from what I have read.
Haha, well I only just discovered that term this week on here! I had a BH5 about 4 years ago which also had George, but never bothered to investigate what it was...thought it was a harmonic on a heat shield or something. It's not exactly the easiest thing to do a Google search on...

posting up for comparison, would love to know what everyone's doing to get like 190+ out of similar setups
Update - the solenoid was faulty. I must have killed it with the carb cleaner and compressed air.
A fellow naki Subaru freak sorted me out with a BBOD from an auto BH5, which got me back boosting again on the primary, but exhibited some strange behaviour (general peakiness and George was much accentuated). I was still getting error 66 at about 6k too.
This evening I replaced the faulty solenoid in my original box and put it back in the car. It's feeling good again but still error 66. I think I'll start a new thread for that one.
Regarding the wiring of the solenoids, it does appear they are permanently wired. I had to pop the terminals out from the big master bbod plug.
A whole bunch of UltraRacing bits finally arrived.
Took 2 days to get from Asia to Auckland, than another two days and numerous phone calls to get from DHL depot to my address.
You'd expect a better service from one of the priciest couriers. EMS is just so much better.
Holy S*** I am in the top 10!!!
Can someone please knock me off that list ASAP, its a disgrace with the amount of power some gents (and ladies) around here have at here disposal
I strongly dislike the number of "Special Edition" Subarus out there. I cant say I would pay more for anything stock or close to outside of a 22B, Coupe or an STI less than 10 years old over a plan old WRX.
