crankshaft bleeder pipe spurting oil into air filter city colf 1.3

it is the crankcase vent pipe

Possibly crankcase pressure from weak rings, blow by, and/or pollution control valve.

we blank off vent pipe but oil is seeping out of oil cover lid oil have to be top-up continoisly

Sounds like you have a lot of blow by. Maybe rings.

what do you suggest to fix it

Maybe a rebuild or replacement engine. If you take the oil filler cap off while it's running is there a lot of pressure. Probably yes. Not good.
