Oil leakage by retaineers

I have a JEPP Kia Sportage 2002 and I escape oil for the retainers the mechanic and change the same and seal with silicon but despite this follow the oil leak tell me because I could or what could it be

Buy a good packaging (retainers) a good silicone and change them ... as long as that is the problem ...

seals that crankshaft, camshaft or valve? If they are from the camshaft or crankshaft, they can be two things, that the sealing seals do not have an oil cutter or that the lip that bit, now occurs in some occasions (they are scarce but pass) that the axis is wearing and the retain that comes from factory does not fit through the wear of the axis and you have to put one with the new valves,

Hello, I read what Kikemec and Alonso2 says and they are right, it is the most logical but I tell you the same thing that I comment on another consultation, I cover the carter's breathtake, the hose that goes from the butt to the air filter, if it is a petroleum, sometimes it goes to the multiple of admission, and lost oil for almost all the challenges, check the hose and uncover it if it is easy to do. It may result. Greetings.

You have to check that you do not have excess pressure in the carter, due to carter oil vent tagger, engine blowing, etc. All this damages you the seals that do not support excessive pressure, if this is not happening you can raise with poor quality seals, damaged when placing them, that they have not done the job and told you that yes and for last wear of the metal parts (camshaft, etc.) where the lip of the retèn closes.
greetings.
