Dumb Question Thread!

[Skatieguy]

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?

[Rosssub]

Looks like hose #1 - IACV Intake air control valve. It's been locked in twin turbo mode/parallel, that hose/valve opens when the secondary kicks in. That will cause CEL's.

[Skatieguy]

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?

There might be other hoses swapped as well, you will need to check them all. You will have CEL fault code 65-differential pressure sensor, or 66-sequential turbo system.

Edit: Connect that hose back up and go for a drive, see how it changes.

[Skatieguy]

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?

Should be close enough, double check 8-secondary relief valve, 5-top of ECV actuator, 6- bottom of ECV actuator.

Do bh5 and be5 have the same length mid pipe?

Or could someone with a be5 exhaust handy measure the length from the dump pipe collected flange to the rear muffler flange in a straight line.

Same length.

PS: are you buying that straight through midpipe on TM? Had the same on mine - sounded like crap, got sick of it and sold.

PPS: any exhaust shop can do the same thing to your stock pipe - paid something like $50-60 to get it done neatly.

Yep, that's the one. Is it just a factory pipe with the reso/cat removed? I don't think my factory one is 3 inch.

Here's what my car sounds like now

How would sound in comparison to that? More raspy?

Thanks for your help and I apologise for the barrage of questions!

[Skatieguy]

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.

[Rosssub]

Unbolt the solenoids one at a time, so you can pull them out slightly to get a better grip on the filter. The filters are just pushed on, try gently rotating them before you pull.

Are GC and GF facelift bonnets different in size? The bonnet I got with my V4 GF8 doesn't fit correctly.

Yep wag/sed same just V1/2 is diff to V3-6 but easy to see the difference.

It's defiantly a facelift bonnet I'm sure about that. Must be the arms as when bolted up the bonnet sits way to far toward the windshield in turn making the bonnet loop not line up with the catch.

[ADIKT]

Should be able to loosen the bolts and move it back a little

Give me a yell sometime if you want - I'm in papamoa and I can give it a once over if you're coming over the hill. Someones played silly buggers

Hoses on a BD are slightly different to on a BE but nothing major

Someone 's trying to convince me, that all EJ208 B4/GTB's came with a varex type mufflers as a standard - is it correct? (apparently, that's according to factory service manuals)

[Divine]

Is the BE shape legacy meant to have a handbreak light?

don't the twin turbo's go from unequal length to equal length exhaust pulses when coming onto the secondary turbo? Certainly would explain a noise change when that occurs.

Yep, the standard muffler has a butterfly valve sort of thing.

Take a look inside the flap on the passenger side in the trunk.

Can Wing Mirrors be tightened at all? When driving over 70k there is a quite a good amount of wind noise coming through.

Or is it a case of using silicone sealant around it or replacing them?
