I'm pretty sure I'm missing some of the PCV hoses. I have the diagram from the FSM, however there's one hose I'm not sure exactly which one it is.

Does anyone have any pics of the PCV hoses?

TIA

I have a pretty good diagram on the same page as my vacuum diagram:

i have a qwestion, there is a rally car at my work 100grand for it and it has the little k&n filters on the vavle cover lines do you think i should do this or stay away.

I've got the same diagram, I'm still not sure though.

I can take pictures of the hoses in question and post. Maybe I'm just missing it.

Nico - I don't understand your question. Are you asking if you should buy the car?

Josh - I included every PCV hose in that diagram... Please do post a picture.

That is a beautiful PVC diagram..... WOW

It looks just like the car, even to scale!
I just replaced PVCs 1 and 14 this week, I wish I would have had that eariler this week, then that special nippel on my rad. broke got an new one in and now a seem a poped in my gas tank, so I get to change that tomarrow, but hey i am putting in a 90, 91 with the drain plugs so ...bouns?
well thanks again VRG3 , the vac hose one is great to. Have you posted more?

nico, the only thing that not having the PCV system routed through your intake will do is keep oil vappor out of there. some vacuum is probaly good for the system. on really built v8's, they sometimes run a engine driven vacuum pump to the crankcase which gains several hp having a low pressure in the crankcase. Im pretty sure its because the lower pressure helps the rings seal better. but it may be a moot point with the amount of intake vacuum the legacy pcv system sees. why not just leave it stock?
sorry for the highjack, but anyone know a reason to vent the PCV system to the atmosphere rather than the intake other tahn keeping oil crap out of there?

Here's pics of the hoses

I know they are not complete. I have an idea which is which, but it'd be nice to either get confirmation on what's what, or see a real picture.

Referencing numbers on my diagram, these are my guesses:

Thanks Vikash

I looked at things closer. Everything was dead on except this guy.

It's #8

#10 was still on the manifold

I've got one piece that I don't know what it is. I don't know if it was something a previous owner fudged to work, or if it's #17

I'll have to post a pic of later.

Here's pics of the mystery piece.

It looks like it was broken off, but I don't know where, and #17 is the only thing I can think of....

I'm pretty sure that, that little guy there looks like that. It goes into the 90 degree boot that attaches to the compressor inlet and the intake resinator on the intake tract (or the mug if you are mugged).

IIRC, it goes on the side nearest to the firewall and turbo. Then I think it connects to the PCV 'F' pipe (i think that's what it is?). Then the 'F' pipe connects to that big large metal piece comming out of the block itself.

EDIT: I got around to looking at #17, and infact that is the little piece. Good luck!

Thanks for the feedback.

Any idea why in the hell it is shaped like it is?

Does the half cut side go into the intake track? I would assume so, but just want to double check.

the side that is cut funny goes inside the boot B cut side facing down.

how the pcv system works thread is a good read on all that goodness.

in the diagram its number 17 connected to number 2.



note that i dont have an f piece but thats where it goes

Yeah, I'll confirm that it's definitely #17. Like Jason says, the opening faces into the compressor inlet. It helps the compressor pull the gases out of the crankcase.

Cool!

Thanks guys. It just looks like I need to buy the plastic piece that runs under the manifold, since it's busted, and some various clips.

Cool. You should be able to fairly easily fabricate a replacement for that piece out of some copper pipe and a copper pipe tee fitting. It'll last longer than the original plastic piece, too!

Or you can do like my dad did with #1, and 17 when we took off our manifold and Dremal it smooth and JB Weld it back together. Looked fine and the car hasnt eaten it yet so i gusse it works but then again ive only been driveing on it like that for a couple of days now.
