Help: KA24DE Vacuum line routing (CA smog legal) - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Jaketenpointo · 01-30-2010, 04:33 AM

Long story short:

I got a car with a DOHC KA. The head was off, and vacuum lines were cut. I need to figure out what the "spider web" of hoses go to on the back of the head. The FSM is nearly impossible to read, and I can't find any good documentation other than removal of emissions equipment.

Also interested in the Charcoal canister lines and etc. I have the canister, but I'm uncertain of which hose goes to where.

Basically reference photos and helpful info would be greatly appreciated (even MS paint).

Thanks
Jake

STEP 1:
Learn to read a vacuum diagraam.

STEP 2:
No longer suck and get your engine running.

Unless someone is feeling REALLY nice I doubt you will find much in the way of "reference photos". You gotta make sense of the diagram man...

I'm feeling a bit generous this afternoon after some breakfast and found an old picture I saved.

Don't know if its right but you can always reference the fsm to double check.

i guess you dont have bigger pics?

red goes to bottom of aiv. white goes to side of aiv. other two go to purging canister.

ok, I agree with you on all 5 lines. the only problem is tracing the lines under the intake manifold. i guess you could blow air through them to test which is which.

So based on this image.

1 > 7
2 > 8
11&12 > T > 9
5&10 > Y > 6

This looks right?

AND the 5 from Wonderbread's post is straight out of the manifold yes?

Update: It almost wants to start. Almost.

The 5 from my post that you're referring to come out from under the throttle body.
