Timing cover leak

Timing Cover Gasket Leak | PriusChat

 

Gunk the engine down, hose it off really well. Drive it to dry it off.
It's very ikely that their is no leak around the timing cover. There is NOT a gasket
for the timing cover, it's siliconed. Once it's clean, you can search for where the
oil is actually leaking from. And how much.
Since your oil level isn't going down, it's not leaking much, and nothing to be
concerned about.
And you do not have to remove the engine to remove and replace the timing cover.

Either the valve cover gasket or the oil pressure switch is likely leaking. This is common.
The oil pressure switch is a $10-15 item, and fairly easy to replace yourself.
