So I just put it back into parallel (somewhat properly) and didn't get any CELs ;D I will know for certain if its solved (for now) when I go for a bigger drive later on this arvo. From what I can see they didn't put the hose from the top of the ECV into hose 22, I'm not sure what else but that's all I changed from how they had it, and I now have no CELs. EDIT: It also feels like I have more power down low which I'm sure isn't supposed to happen?

This might sound silly but thinking back and reading all this now I think what may have been holding the ECV open came off on the way home (before my first CEL) and then after opening it up again I was hit with it. Might put it back to parallel and try sort that out, at least until I can figure out what's wrong with it in sequential mode.

Sounds to me like it slaps shut, checked the primary wastegate hose and did not see/feel/etc. anything inside the hose. No wire nearby but I could push a cabletie the majority of the way.

No boost gauge sadly, I think I can hear the bpv going off, I only got to drive it for 50kms (parallel) before I was first hit with these CELs. but when I got home it would at least push you into the seat a bit, even after putting hose 1 back onto the IACV IIRC it would accelerate well enough. After the first 2 gears.

Still getting code 66 turned up around 3k rpm just driving normally, feels sluggish don't know if it's just me seeing as I'm not used to twin turbo, but it felt much better acceleration wise back before the CELs first turned up.

My iPod camera is awful but this is what was in there, bit smaller than I expected Will report back once ECU has reset whether its solved now or not.

They seem to work at the start and then slowly stop with the ECV stopping first, the ECV opening/closing about 4 times before slowly getting weaker, and the IACV a bit more. Are they supposed to just keep going? EDIT: I also found this while trying to remove the secondary relief valve; is it supposed to be in there? Looks like it completely blocks it.

I just tried this, code 65 reappeared but I hadn't reset the ECU so 66 was still there too. I took it for a quick drive, got CEL (65 this time?) but no fuel cut/any cut over 3500 when the CEL hit. What are the chances of this being my issue?

Thanks mate, did find that hose 1 had come off so will be cabletie that if i get cel again and the hose is off once more.

I don't really know how to check for a faulty one so I'm going to try what I linked in the edit first, looks like its possible someone just switched it over to parallel turbo and didn't hook hose 8 into hose 22. Will check all other mentioned things as well though. Just want it to get running without CELs before I try anything different.

Hmm this thread may be more relevant now to my situation than the dumb question thread. I had both codes 65 & 66 myself. Code 65 seems to have been removed by putting some carby cleaner through the BBOD and hoses directly connected to it. When I bought the car it was in "parallel" turbo mode, hose 1 was blocked off and where it goes on the IACV had a little cap over it. Now. The car seems to trip code 66 in the higher gears, for example today I was in 5th and put my foot to the floor to try get it to trip the CEL, it got to about 3300rpm in 5th before what felt like fuel cut happened and then going into limp mode with a solid CEL. The car is a 1998 BD5C RS, EJ20R, manual, with 108k on the clock but was also parked up for 4 years, apparently has a chipped ecu, headers and "big bore" exhaust. I also cleaned out the primary boost solenoid today with no effect on code 66. I can't comment on whether the car has lost power or not as I have not driven it or any twin turbo legacy long enough to know what they really go like, only a V7 STi which definitely felt much quicker, cleaning out the BBOD did make it feel smoother and like it had more power early on. Would a faulty ECU be a possibility here? Both single and twin turbo modes feel fine to me until code 66 is tripped. EDIT: Had a read through this: http://clubsub.org.nz/forum/showthread.php?32559-Idiots-guide-to-converting-your-legacy-to-parallel Looks like I may have to go through all the checks here as this sounds like what happens to me: "In theory you can now go for a drive, and then watch the check engine light come on after the first few times you floor it. " And I see hose 8 is where it should be.

Nope, looks like tomorrows job though.

Changed the oil yesterday, cleaned out the BBoD hoses and the ones joined directly onto it. Got rid of code 65 and seems to go much better in general but still getting code 66

okay this one really is a dumb question, I am up to "4, remove the little breathers from the top of al the solenoids ( 4 of them) . **circled yellow in pics...**" How do I actually do that without breaking them? Seem a bit flimsy for me to just randomly try getting them off, hoping for the best.

I connected it back up on the drive home, certainly fairly lack-luster compared to it blocked off, CEL still came on, will go through them all tomorrow when I can actually see. EDIT: Also this is a BD5C will the vac hoses be set up the same?

So just sticking it back on doesn't stop the CEL coming up somewhat randomly, would an ECU reset fix it if this is actually causing my CEL?

What is this here actually doing? '98 RS Legacy on the drivers side. Seems to make the primary keep running or at least reduce VOD but will it wear anything other than the primary turbo out quicker? Also code 66 that seems unrelated to this hose, are there any vac hoses that are more likely to gunk up than others that I should check first?

I mean really I should have gotten a pre purchase inspection or something but it was a split second decision to bid, not sure if that would have turned up in the PPI anyway. luckily I could turn the car off and on again to get rid of limp mode/ solid CEL.. Basically drove like I'm supposed to home with no issues at least.

Picked up my $2510 Legacy today from Whangerei, enjoying it so far except for the fact that I have already been given a CEL that I will hopefully diagnose tomorrow. Not sure if magically happened 50kms away from the dudes house or he conveniently forgot to mention it to me and or on the auction.

Err maybe not exactly "my car" yet, but bid and won this.. http://www.trademe.co.nz/Browse/Listing.aspx?id=723411029

Yes now I just have to hope I get there before everyone else

Anyone able to do another for me, please? 7A8GF090705038820 GC8-038820 Hoping it is a V2 STi not just a WRX. No applied model code given to me yet. EDIT: Managed to find this myself. Hopefully the dude gets back to me as I shall be snapping it up if I can.

They want $4500 so may offer them $3500 and go from there..

How crazy would you have to be to buy a cheap V6 STi with 228xxxkms without a pre purchase inspection? Looks somewhat tidy at least..
