Usually when oil is coming out of the breather, there is excessive pressure in the motor.
this is caused by a faulty PCV system.
try changing your PCV valve and see if that fixes your problem.

I switched my zetec over to 10w-30 at about 75000 miles and ran 10w-30 in her through winter and summer for two years. I tried 5w-30 in her but she hated it. Then I got in the wreck and no more zetec. She had 120,000 miles on her, 45,000 miles of castrol syntec 10w-30 and she had full compression on all four after the wreck (engine was still perfect cept for radiator and power steering).

Now I have this honda accord with over 180,000 miles. I switch over to castrol syntec 10w-30 and voila, perfect. The car runs like a dream, no oil leaks whatsoever and she no longer burns oil.


So whoever said you can't change engines with over such and such miles.... you're a liar!

This will happen quite frequently (I hesitate only slightly from using always) when switching from dyno to synthetic on medium to high mileage vehicles. This is because synthetic has smaller molecules which will find and penetrate smaller cracks than dyno. There's a high chance you can stop the leak by switching back to dyno, or using autorx at http://autorx.com. See http://bobistheoilguy.com for any questions you ever had on oil, lubrication, filters, and additives.

Pcv system needs checked out. Should be something on this I remember others having this trouble, regardless the type of oil. I don't have a Zetec, sorry no experience.

I actually did just change the PCV valve yesterday but the oil is still coming out of the breather.

Synthetic does not cause leaks. PERIOD.
For a leak to start after the change, the problem had to exist allready. In other words, you had big problems in the VERY near future.
Synthetic beats regular oil in every way. Will not go into the power or fuel mileage debate here, or even value for money, but it IS better oil.
Synthetic blend is basically just snake oil. Either use dino oil or synthetic.

Well, i spoke too soon, it's still leaking. I've come to the conclusion however that it only leaks when im really pushing my car. I drove around like an old guy for the most part yesterday with no leaks but on my way home last night i drove like normal and there was oil everywhere....

i hate to get on everyone's bad side about this but i believe the cars need 5w-20 instead of 5w-30, here is why

oil recommendations

and read the whole thing before you bite my head off about it, and i am not trying to say that all you out there using 5w-30 and any other weight are wrong just maybe uninformed
