914World.com _ 914World Garage _ 1.7L Air Cleaner connections

Posted by: BCinSC Apr 18 2004, 11:08 AM

Reviewing hose connections, I notice that I'm likely mis-connected. Per Haynes, PP, and convetional wisdom, the top nipple should connection to crankcase ventilation and the bottom to charcoal canister. Per diagrams and arrows on unit, the two nipples should be inline, however, this puts the snorkle against the firewall, which just doesn't fit. Thoughts?

The snorkel moves if I'm not mistaken.

Can you shoot a digital pic of your engine ? It will help us in determining what goes where.

One of the other club members may have a pic of their 1.7 engine for reference. I personally only have pics from 2.0 engines and 6's.

I was going to reply and then I realized that I never had an air cleaner on my 1.7 so I don't know where the hoses go.

My non-reply was just as good as your non-reply.

No, telling him to take a picture doesn't really help in my book.

At least we don't work on 914s for a LIVING... heh, yeah.

Sooner or later someone with a 1.7 will see us "non-replying" and reply to him.

I can only think of one 1.7 that we work on (Benjamin's) and it is the loaner motor for his 2.0 build.

I don't think it matters which way around you go. Put it together so it all fits. I believe that both fittings (they're on the air cleaner, yes?) simply supply air at "ambient" pressure, or in the case of the charcoal cannister lines they supply air into the air cleaner. They should all wind up in the main chamber of the air cleaner, so there should not be a difference between them.

BCinNC-
Dave is correct, I have a OEM 1.7, and my vent lines are connected from the "flashback valve" (#12) in the Haynes, to the bottom nipple on the air cleaner. I have this nipple facing the left rear wheel under the air intake duct. The snorkle aims out to left at 90 degrees from rear of car, lots of room and fresh air there. The charcoal can line comes from right side and hooks-up to top nipple on air cleaner.
This fits best and works well for me.
Hope this helps...

That's how mine was, but not how the book SAYS is should be. If it doesn't matter, wouldn't VW/Porsche have put them both on top or both on bottom? Pix coming

Wow this is playing right into my car project. found the additional hose that comes from the vapor canister. Not that it was any good. I need to replace all of them lines too.

So hurry up with the pics. kinda "I'll show you mine if ya show me yours"
