1- loose bolts somewhere on the motor- usauay the drain bolt-
2- gasket failure from wear and heat or in some cases the installer of the part where the gasket was used unevenly tightend the bolts.
3- oil hose failure- either the hose has crack or split or the hose if connect to a metal fitting came lose
4- your motor is shot because you let your kid take it out on a Friday night and he/she decided to try out drag racing.
Suggest- power wash the engine bay of the vehical -let it dry - put a little oil into but don't over fill it- have a helper start the car and just watch the engine - alternate between the top and bottom of the car and if it starts to leek- watch out for belts and moving parts. Because a finger is a terrible thing to waste.
Yes.
An oil leak is always going to be out of the engine as the engine contains oil and the car does not. I think you are saying you are loosing oil with no apparent leak. If that is the case the engine is burning oil and that is why you see no leaks.
It will continue to leak oil and if you do not add oil regularly it will eventually cause engine damage.
Need to know the cause before it can be fixed. Could be anything from a simple oil leak to a major engine overhaul.
A loose, improperly aligned or worn-out oil filter are common causes of car oil leaks. A loose or improperly threaded drain plug could also cause an oil leak to occur.
Several things could cause an oil leak in a 206 Peugeot including a bad cylinder head or a problem with a pulley oil seal. There could also be an issue with the rocker cover gasket.
I would not expect a valve cover leak to cause a car to stall. A valve cover leak can fill the spark plug area with oil which can cause rough running.
It can leak at the connections or the cooler itself could have a hole in it.
Oil can either be burned, or it can leak
Oil probably.
can exhaust manifold leak cause you to burn oil
Yes, oil can leak through the switch.
