See pic for crankcase breather/oil trap connection :-

Breather_Pipe_02

Is this correct, or completely wrong? Cannot find any other suitable connection, as I'm using pancake filter.

Er, very wrong. The pipe from the canister (cannot remember the name, PVC, PCB or something like that. Someone will know) vents to atmosphere or back to the air filter. It is the crankcase breather. I think you have taken it to the brake servo take-off.

Hi Dick, this is a job I'm on with at this very moment. I will take some picks tonight and post my solution. In essence I have a catch tank and vent the breather to that.

Later.......... Neil

The breather vents into the inlet manifold, as you have done. mine is the same...

Thanks for all the replies. Had a feeling that it might be wrong.

Nash - will check your pics with interest; Mike, I guess you'll also be interested.

IIRC, on the original Escort installation, this can was connected to the air filter, to re-circulate the oil vapour (I think?).

This is how my Xflow was plumbed when removed from the donor.

There should be a PCV valve in the catch tank which is 'sucked' shut when there is a strong vacuum in the inet manifold (i.e. small/no throttle opening).

As the vacuum in the manifold decreases (i.e. as the throttle is opened) then the valve opens and the crankcase gases are vented into the inlet manifold and burnt in the engine.

As Gary says - what you have in the picture is the standard setup on a x-flow.

As for how well it works? It probably did work OK when new and clean. On my engine, the tin box was full of disgusting oily crud, and the PCV thing was locked solid.

Now the engine has an outlet from Burtons in the hole where the box went, and a pipe to an overflow tank.

Had'nt we used to put out hand over the oil filler cap to make sure there was a small amount of vacuum in the old days...

If it was blowing we considered the rings n things were shot... lol... 56K head off de-coke hahahahrrrr....

I still think a small amount of vacuum in the block will stop small oil leaks when the engine is running..

cheers....

Ok guys here is my solution to the Crank Breather.

My contention is that its not a good solution, performance wise to put hot gases into the inlet (unless forced in by a turbo). The reason I say that is that if you have the air filter taking in hot / warm air you get a performance drop off with the engine. Hence I've vented mine to a catch pot (or at least I will when its finished.

NOTE the piped photo is a mock up I did in Photoshop to demo. as I haven't finished the job yet.
