15 quarts of oil in my engine

[stelan]

Nope, no deep sump, standard oil pan, it is crazy, yes Im doing spark plug tubes as well, prevoius owner probably was smoking something, he did say that he replaced the AOS about a month before he sold it to me.
The dipstick showed above full and the dash gauge showed all bars lit.

Now, almost 16 quarts is what I drained, and it has been leaking, inagine how much oil the guy actually poured in in the first place!
