My mate has a xr3i escort cab, mk4 cvh mfi! he keeps empty the air box of oil but a couple of days later and days later its full again!
Any ideas have cleaned oil breather pipes etc, it seems oil is coming from pipe from rocker cover to airbox?

Cheers Pez

 

snap, me got this prob 2

 

Just a hint ...you are overfilling the engine with oil???just maybe...
there should be a small hole at the bottom of the air filter box...maybe it's closed
meybe the oil filter has burned and keeps stucking the hole

mine box has two compartments. one for the air cleaner and other for oil cleaner filter, both have holes down at the bottom

 

have you got the oil vapour seperator the right way up ??? how old is it ???

it sits on the l/h side of the rockercover breather large black bit of plastic..
it has a mesh in there that gets caked up .. just go get another one .. should help ..

 

mate

your motor sounds poked

do a compression test , me thinks your rings are gone
cvh's blow oil like a bastard when they are on the way out

 

Shit breathers on these engines.Ford revised (changed the design) 4-5 times due to this problem.Try an after market breather(BAILEY).Also your engine could be on the way out.Try cheapest option first.

 

cvh engine is a notorious heavy breather as mentioned above, try and external pot that vents to atmosphere, as all that oil fumey crap going into your air filter means it obviously goes back into the engine. Not gona be best for emmisions, perfermance etc. Or just have a longer bit of hose going to underneath the car, bit antisocial though. lol.

 

its ok the engine died when my mate was on his home from work the other day! so rebuild on cards for him, trying to talk him in2 sticking a 1.8 zetec bootom end on it as he has 1 in the garage!
