I'm not an exprert, but I would guess that the metal shavings that you are pointing at with a screwdriver are what's left of the bearing for the crank shaft. I do not think that this would confirm damage the the head as the damage that I can see is in the bottom end.

I think that this is why the engine is seized.

i missed the s2ki.com bylaws that state my posts have to "add value" to a thread.

i'm stating my opinions as the thread unfolds.

it's not popular with you guys, but that's not going to hold me back from stating my opinions.

i think it's pretty interesting that spitfires provides an explanation of how the OP can be at fault for this as well.

someone want to inform the dealer of this explanation?

didn't think so.

is everything that is posted on s2ki.com the truth, the whole truth, and nothing but the truth?

get real here. if the dealership had a thread on here, this story would get a helluva lot more interesting, don't you think?
jyeung, you're getting a little misguided here. I'm not totally ruling out the OP as being at fault. But judging from what's been stated, it doesn't sound as if the OP did anything extreme to cause this problem. We can only go by what's been stated. Yes, he took a turn in neutral (you may want to try to get over it - I lost count how many times you emphasized this). Yes, he used some terminology that was not representative of what a "car guy" would use. However, he's done his best to explain the situation and hasn't given any reason for people to ignore him. You are not going to know everything there is to know on a given topic and that's why others are here to help.

So please cut the OP some slack. You're also trying to provoke fights in your recent post. Give me a break - nobody is intimidated. Try to take a step back and think about why nobody is really providing a lot of support for your comments.

Good luck to the OP. Sorry for posting - I probably should've just refrained.

i don't know if the OP is at fault.

but 9 pages is enough to conclude that we don't have enough facts and it turns out to be very possible that the OP did over-rev, as the dealer suggests.

are we receiving any information to suggest otherwise?

so at what point do we all say, as much we we'd like to help, we can't be certain that the dealership is even at fault here.

i think everyone else should take a step back and think about why they all believe this is the dealerships fault.

In the picture where you point at the "shavings" with a screwdriver I think you're pointing at parts of the thrust bearing.
IMO a severely damaged thrust bearing could seize an engine.

There was a post not that long ago about an engine stalling as soon as the clutch pedal was pressed.
That turned out to be crank walk, aka failed thrust bearing.

When you take corners in neutral, do you keep the clutch in during the turn or do you actually shift into neutral and release the clutch?

Just a wild guess: if you keep the clutch in during a turn in an engine extremely low on oil, you could - in theory - have an oil starvation issue manifesting itself mainly at the thrust bearing.
The oil level has to be low enough to - during the turn - be all swept to the side and away from the oil pickup point.
(that's the slot with the wire mesh at the bottom of the oil pump)

Yes, it's the thrust bearing. It's located right between cyl.4 and 3. I noticed a very tiny glimpse of a bearing part in 2 pictures.
Repair is possible.
I have to disagree with the "wild guess theory": the thrust bearings are not connected to the oil pressure system.

taking a turn in neutral is a huge clue as to the competence of the driver...is it not?

keep in mind, there are many s2ki posts that show many drivers think they can't over-rev because they are protected from the engine cut-off feature.

i don't know about the OP...but his facts are lacking, and his statements are suggestive of driver incompetence.

so while you guys say to get over it...i'm saying it's a big clue to what may have caused the problem.

To help the OP and to satisfy my own curiousity, what would need to be done to repail this?

I'm guessing replace the crankshaft and machine the block and replace the bearings?

perhaps you didn't over-rev. perhaps you did.

we have 10 pages here and we haven't got a clue.

good luck to you.

How do they get lubed then?
Just by what draines from above & splash?
There's no feed through the crank or block?
With feed through the crank I'm thinking about what leaks out of the main bearings.
If so, than agreed: that's not the oil pressure system.

I can't find the pics I've seen on here of the thrust bearings & crank.
