Or, a single line from the TB to the accordion hose with T in it going to the catch can. If you put a PCV valve on the accordion hose end that only allows flow to the accordion hose, that will put max vac on the can. The line needs to be a -10.
Ian needs a PCV on the TB end because he is...
I did misunderstand and that still won't work.
Think about this...the idea is to put vac on the catch can and pull in vapor to the can from the cam covers. Is that possible with the way you have it set up?
This is the last time I'm going to say this. That is not going to work...at least if you want a functioning catch can. The PCV valve between the TB and cam covers will just stop the reverse flow necessary to push vapor to the accordion hose (or catch can in your case).
I am really wondering...
Unless you route the line like the diagram (and like Ian's pics), it's not going to have much oil in the can. There is not enough vacuum at the accordion hose to do squat. That is not what Ian is telling you to do...he gave you a cliff notes history and said the cam cover to accordion path was...

Discussion follows...you will see it pretty much mirrors what I said earlier here. To be honest, a catch can is not worth the time and effort IMO. But if you want to run one, that post and my comments...
I've never used it, so I can't give you any personal experience. I have used Ford gear oils exclusively in my diesel Excursion (4 WD, auto) with excellent success. Looking at the site tells me it would work and it meets Ford long-life requirements. I'll tell ya though, MT90 is hard to beat ;)
Raw - you are on notice. You are no longer welcome in this thread.
I've seen it a few times, mostly when the PCV was ghetto rigged. I would do a compression test for peace of mind.
Ummmm and where does that compression go when the valves are shut during a compression test?
A leak down will provide good info too, but it is not the only method.
It's time for you to stop the pissing contest wise guy.
Oil pressure has nothing to do with it. Neither will oil level unless you have it waaayyy over filled. A way to determine if you have excessive blowby is to do a compression test.
If I read this right, you basically put a catch can between the cam cover outlets and the accordion hose. Is the...
Dave - you have the right idea ;)
A minor correction, over distance the psi decreases effectively reducing the rate of flow for a given pipe diameter. The larger pipe you speak of is producing the volume necessary to keep that BBQ hot.
One other thing to keep in mind...bigger is not always...
First of all I have explained it...you are too hard headed to get it through your noggin. The TCCS book I have has nothing to do with it...what is your point? Just because I have a much higher IQ than you do does not give you the right to make snide comments like this. Your "experience" does...
Would you explain how any significant amount of pressure differential (enough to pull vacuum) is produced by the turbo intake pipe, otherwise known as the accordion hose?
Where exactly is this vac line to up-size for the crankcase to cam cover vent?
I'm really excited about the opportunity to...
