Wow... I remember those pics but i didn't know that it was your home & cars. The photos made me sick but I can only imagine how you must have felt.

 

Hello there!

Ferrari uses liquid nitrogen to shrink and then fit such engine components. This task is performed by two robots called Romeo and Juliet.

 

Hi Bill,

Sorry you have to go through this, but you are definitely doing it the right way.

Will you put it on a dyno before it goes back in?

 

Hello friend.

Yes, I saw the 599 Factory video.

Shows them fitting valve seats with Remeo and Juliet.

I wonder if they use the liner puller or freeze them at the factory?

If you freeze them, you dont need the special tools to fit the liners.

 

There ya go, special tool to fit the liners.

I dont know why they wouldnt be seated hard Bill?

They should pull straight in man. Perhaps an issue with the deck height on the block?

We have NEVER had an issue with fitting liners, but our blocks are cast iron. Not alloy.

 

Thats for valve seats, not for cylinder liners.

 

It would seem that you are quite right sir.

 

on the bottom of your attatchment is a note about the first liner possibly causing issue with sbsequent liners if not seated fully.....
.....i know on the bmw v12 we had a hella-time, and found we had to work super-super-fast, more then we thought, as the block cooled so quickly.....finally it was a sprint-race, and suddenly in she went!? hope this helps?

PS reminds me, we also let the block linger for a while in oven-box, not just as soon as when the block reached the temp, mind you that isn't as valuable as anEnzo block, which is also likely made of less aluminum mass, so warpage would be of concern, but these were our observations

 

Any update on the liners Bill? Or a general update. Thanks! Hope everything is getting figured out.

 

I had that problem. The dealer found several ends from valve springs in the oil during an oil change. I had to ship the engine back to the factory for a complete rebuild because it was clear to me that they had a problem with a bad batch of springs and I did not want any of them left in my engine and I wanted a through inspection to see if there was damage to any of the cylinders. I had to pay for shipping and removing and reinstalling the engine and Ferrari in Italy did th rebuild for free. The car was about 15 months old.

 

If a seat was to fail it would have fallen out of the head as one piece. All seats are present and accounted for.
It looks to me like the valve itself failed. Are the keepers still holding the stem up?

 

By now you must be really anxious to get behind the wheel of your Enzo again.

All the best,
Andrew.

 

I would love to see dyno numbers from this rebuild!

If you ever have the car near Salt Lake City, I've got free dyno time with your name on it!

 

Good to hear mate.

 

Nice to see some good progress on this project

 

Looking good mate!

 

Can you please post some pics of the car with the engine removed? How is the removal prossedure?

 

I once took a couple of pictures of an Enzo (not Bill's) with the engine removed. I don't know how helpful it will be, but here you go.

All the best,
Andrew.
