catch can 1
catch can 2
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?
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.
if it helps the photos of my set up are here (if I have managed to do it correctly or in my photo archive

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

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?

Well Raceline & Omex certainly don't. Which 'main' tuner where you refering to?
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.
All engine were spec'ed wet sump, as I did not wat to go dry.

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?

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.
