I took a bunch of digital pictures of the engine when it was out of the car, on an engine stand. The hole was located at the dipstick, about 4"x4". The engine was not reparable. The mechanic at the dealership just said the engine was shot, never gave a reason as to why it failed (kaboom). I really don't know if it was a series II or not....
Okay, several things here:
1) Engine flush basically _is_ a quart of oil, but with assorted goop added (varies by brand) to thin the overall viscosity, dissolve accumulated sludge and wash everything out. Letting it drain for a long time afterwards is a plus. (The few times I felt the need to use the stuff, I added it per directions, ran the engine and/or drove the car round the block as instructed on the can, then left it draining while I went out to lunch or worked on other car stuff for a couple hours.)
2) You said they had a videotape of the servicing that shows them _not_ adding the flush? So did they use it, or not? You got to see the tape yourself? Do they still have it?
3) Even if they had added the flush, they wouldn't drain all the rest of the oil first. It'* added to the existing old oil in the crankcase, not all by itself after the old oil is drained.
4) You said, "The mechanic at the dealership just said the engine was shot, never gave a reason as to why it failed (kaboom)." You're going to need more competent backup than that if you really plan to press your claim with Valvoline. You're going to need someone who can examine the old engine and write up a coherent analysis of what they think went wrong.
It sounds like you may need small-claims court to get any money back from the shop that you're blaming for this, but before that you really need a better summary of what the heck happened. I've read your posts twice so far and I still can't piece together exactly what did or did not happen to trash your engine, and I'm just a casual observer; a judge is not going to be more sympathetic.
So write up a chronology in your own words of what happened, one thing at a time, and find somebody at your dealership who can describe clearly what failed in your engine, and why they think it did that. Good luck...
