Zetec 2.0 Catch tank set up?
Bought myself a catch tank but I'm a little unsure on how to set it up. Made a post about oil usage the other day and a few commented on how
they set them up but I can't access the post. Looking at the engine, there is a breather at the front of the block below the exhaust manifold
that has a pipe that runs into the inlet. Then there is a pipe on top of the cam cover, is running this pipe from cam cover to catch tank, then
venting to atmosphere enough? Or should I run a T piece, block to cam cover then to catch tank? The catch tank I've bought only has two
inlet/outlet. I'm a little uneducated in this field but if someone could shed some light on the best way?

catch tank.....
I have just reached the same point.........I was going to join the two breather pipes with a T piece and then to one of the pipes on the catch tank.
Then fit a small K&N type breather to the other. At the moment the two breather pipes have a mini breather each. Sure this set up will be fine??

Do not T them together. Run two separate lines to the catch tank. If you T them you are potentially putting crankcase pressure into the cam-cover,
which can't be a good idea.

forgot to mention I have a blanking plate on the other breather so only have the Cam cover side.

Not to tee....
Good thinking.........not to tee the pipes , all crank fumes etc. coming from one exit point , you presumably have no issues with blocking the lower
breather......

Non at all, engine built by dunnell, done several track days and lots of road miles with no problems

Cheers for the replies, my main concern is that the catch tank doesn't have a filter, just two inlet/outlet so if I ran two separate pipes how
would it breathe? Also blocking the PVC looks like a nut ache in fwd cause the exhaust manifold sits right above it?

I bought a cheap catch tank for £20.
It came with 2 sets of barbs, 2 large ones & 2 smaller ones so I am using the smaller ones for the pipes to go on & I drilled & tapped the
catch tank lid so that I could fit one of the bigger barbs on top. Got a small filter that fitted onto the top barb for about £3.50.
Job done :-)

Pretty much the same as mine, just bought a cheapo so will try what you've done there, how have you routed your pipes? Is there a specific
inlet/outlet pipe on these or just pipe them in wherever?

Please don't block the crankcase breather, it is there for a reason. Use the standard Blacktop breather unit but remove the valve. Pipe that
to the catch tank and run another hose from the camcover.

Why do all the main zetec engin tuners block it off then?

Mines a silver top, don't know if they're different, if I pipe the from of the block and can cover what about the pipe on the side of
inlet manifold where the pipe from the block goes?

Well Raceline & Omex certainly don't. Which 'main' tuner where you refering to?

Dunnell, provided engines for most ford based series
Scholler
Ric wood
When I spoke to raceline at the time of getting my engin sorted was not mentioned and no comments made after I had it done and got there sump
fitted.
As said have done several track days and may road mile with no issues or leaks.
May be different with forced induction due to increased pressures

Why would you so this when the blacktop unit is so effective. It makes no sense to block the crankcase breather. Are you sure Scholar and Dunnell
are not expecting dry sumped engines which would breath through that?
But, fill your boots, your engine.

You need to blank off the hole in the inlet manifold. The stock system works of manifold vacuum to pull the gas out of the crankcase and send it
through the combustion chamber. This why you need to remove the valve from the Blacktop breather. Get hold of the Blacktop one and not the Silvertop
unit as it is more efficient.
If someone wants a very nice, redundant, blanking plate I've got one in the garage but on your own head be it.

Right I'm a complete noob when it comes to this, is a plug or cap enough to blank the inlet port? Also, when you refer to "valve" is
this the spring loaded part in the piping to the block/inlet or is the valve what is actually attached to the block below the exhaust manifold? I have
two PCV pipes, one has a small spring loaded valve and one has a larger one? Is this what you're referring to, again sorry for the questions but
just want to know how it works so I plum it in right?
