The first time I thought it may be a
leaky oil pan gasket so I replaced it (without much analysis because it was easy and the part was cheap).
it had new shocks, front end completely redone, new rear halfshafts, newer brakes, has all new injectors, new glow plugs, newer battery, has new
filters oil pan gaskets and many more!
Further services in 2016 included a
new oil pan gasket, auxiliary fan, factory battery, fuses, bulbs, and accessories, while an alignment was performed concurrently with installation of the new tires in April 2017.
In certain cases you may have ruined the piston rings, fouled the spark plugs, or busted your oil seals (rear main seal,
oil pan gasket, cam cover seal, etc) but I imagine if you drained the oil to the proper level and removed the pools of oil in the combustion chamber, the engine would eventually fire, burn off whatever oil was remaining in the chamber, and continuing running without any catastrophic issues
And, wouldn «t you notice
a oil pan gasket leak when you saw other 2 leaks?
More common areas of oil leaks are
the oil pan gasket, valve cover gasket, oil filter cap, or the oil filter housing gasket.
New rear main seal and
oil pan gasket.
Oil leaks from a valve cover and
oil pan gaskets are common in a V6.
