loss of power and air leak

[Asaneale]

this morning my 1.2 04 clio lost power and got an air leak from the rear of the engine which gets worse at higher revs. im assuming a gasket has gone but unsure of which one. there is also a small oil leak at the rear could the two be related? any help will be much appreciated

I can't help with the diagnosis I'm afraid, but I know that if gasket valve seals are too worn out then they will be leaking some oil in that general area.

cheers for your help, can this also cause an air leak. if its any help the oil leak has been there a couple months but the level has only dropped a couple mm.

also the air/vac leak is more noticeable on load
