Engine breather set-up for Zetec

It will certainly help if breathing was restricted beforehand.

Have you got the blacktop Zetec? If so the PCV is at the back of the block (assuming you have it on a rear wheel drive car and not sideways) on the right side. Look down below the headers at the rear side of the block and you'll see a pipe coming out of the PCV which is simply pushed into a rubber grommet - you can just pull it out. Unless the valve is being operated by a vacuum source, which your setup isn't doing, then you risk the same problem I had,

I found my valve. Gutted it as shown. Engine still pumps oil from the rocker cover, front and rear seals.

Mk2M - what breathers have you got and how arranged? If its still forcing oil out of seals and the breathers, you've got serious blow by / crankcase pressurisation issues.
