Getting a slight smell of oil , through the air vents, when staitionary or moving , there is no oil leeks ,from under the car ,i had it in the garage, on there lift , so was able to see properly, with a inspection lamp, could it be the breather pipes or the pcv valves ?

Thanks stu {sussex stu } seems the oil smell might be rocker cover gaskets

It has to be an oil leak burning off in the engine bay to be able to smell it through the vents. As its burning off, you wont nessarily get any excess leaking to the ground.

 

Rocker cover gaskets is the most likely issue.

Ta ,Stu said the same ,So how long does it take, to replace gaskets aprox,

depends, it`s a plenum off job to do the rocker covers, don`t forget to check the half moon inserts too.
