Just throwing this out there as a last ditch effort to see maybe I missed something stupid before I start rebuilding an engine:
Someone borrowed my grandma's car [2001 Lexus GS300, 2JZ-GT engine] and it died while driving (completely shut off). Took it back to the house, it barely started once, just barely a second time after pumping gas, and not at all a third time after running scan on ECU. Computer has misfire codes on cylinders 2, 4, and 6. Ordered new coils and wires because I was pressed for time and couldn't do anymore diagnosing. The coils come in, I pull out a plug just to check and its covered in oil. I stuck a twig in the spark plug opening and the cylinder was completely full of oil. Matter of fact, it didn't even drain down as you would expect it to after sitting for a week.
My diagnosis: piston rings are completely shot. Engine rebuild.
Anyone disagree? Anything else to look at before?
Thanks everyone.
