Code 66
#1
Posted 07 September 2017 - 08:57 AM
I cleaned and changed all the vacuum hoses in the solenoid box before the swap, did them one at a time so they're all where they should be.
I've checked the vacuum tank and it holds vacuum. Had it running in diagnostic mode and it seems to open and close everything.
Anyone got some ideas at where to start looking?
Cheers

.. hard to say.
Code 66 (if you search) seems to be caused by any number of things -- mostly mis-plumbing or the like.
some descriptive stuff here may help: https://www.scoobyne...legacy-gtb.html
I think it pretty much boils down to malfunction of something in the (complicated) vac control system.
- no boost suggests the intake secondary relief valve might be stuck open - try blocking it and see if you get primary boost
- check that the actuators pump back and forth in diagnostic mode (ECV and IACV) - you did this
- check the vac tank is holding vacuum -- should be a fair bit there even a couple of minutes after the engine has been shut off - you did this
relief valve would be my first bet
also see here, which also points to busted secondary relief valve or possibly maladjusted ECV:

Also is the restrictor pill for the primary wastegate in the turbo side of the vacumm hoses or in the hose going to boost control solenoid in the wing (hose 23 iirc?)?
I replaced the hoses going to the solenoid just want to check and see if it should be there or not cause I can't remember if I put one back in or not.

restrictor is in the line between turbo outlet and T to BCS.

is your primary turbo ok?
Wastegate shutting?
really can't see how it can develop less than ~7psi (wastegate) with the bypass blocked unless one of those two is rooted.
Only other option is the blow off valve leaking.
Any other (post-MAF) leaks usually lead to serious overfuelling (black smoke).
btw - I wouldn't worry about codes with the relief valve blocked.. they should go away when you reverse that.

Will block the blow off valve and see what happens

nah - should be fine with no exhaust.. unless the O2 sensor is missing, maybe.

MY00 Red RX, a nice daily that was sold off once the B4 became reliable...
MY02 Blue B4, aka 'The Project' - v8 JDM STi engine package and assorted other 'goodies' - Sold, then bought back for parts. Stripped and crushed.
MY03 Blue RX, the newer old daily, pretty well more B4 than RX now... In the process of being converted to the track toy... Watch this space!
MY02 Silver Wagon, H6 conversion, full blue/black leather and almost full black interior to go with it.
MY03 White/Silver H6 Outback, donor car for silver waghoon.
MY97 Silver RX, acquired to become track car, but plans changed. To be stripped and scrapped in time.

if you've got a A-C JDM, there's only one O2 sensor in the primary up-pipe.

Also, have you physically checked the turbos arent seized? The turbine/compressor wheels spin freely?

Will check for a pill in line 1, I remember putting one back in when I changed all the hoses but can't remember what hose it was.

Sorry, my bad.
You are correct, pill should be in line #2.
(Got confused with line #1 mod).

I have done the hose 1 mod too.
Are there any other pills i could of missed when I changed all the hoses across the manifold?

In your application, there's only one in the solenoid box (#2) and one in the little hose coming off the compressor cover of the primary, before it hits the tee.
How is your (main) BOV set up ?

I replaced the 2 intercooler hoses with silicone ones during the swap and checked the clamps this arvo and they're still tight so no leaks there.
Any other things I should check?
