Thanks

Thanks for the responses and discussion here. Looks like on a reman'd engine, the block is used but remanufactured and the moving bits are generally new. Works for me. Thanks for the insight.

Then there is an overrun to produce x amount of excess engines. Then once production ends, its over. I'm willing to guess that BMW is not making any more S65s at this point but they have a bunch on the shelves.

I think our cars will run into an issue in the future...used components will be pretty expensive. If you look at an S62 and what they command...I think the S65 will be similar. Not to mention the S62s are somewhat hard to find. Then we will maybe run the fate of the E30 M3 and its S14. Many just drop in S50s because finding an S14 is so hard AND its expensive.

With the S65 being all aluminum, I do believe overheating will render the block and head scrap metal. That's the problem with the M54...its a common engine but its mildly challenging to find a really good block. Overheating scraps a lot of engines. Which is odd because that was a widely used block from 01 to 06 in the 325/330/X3 2.5/X3 3.0/X5 3.0/525/530/Z4 2.5/Z4 3.0...and I'm sure I am missing a model or two.

So take care of the S65 block and head!

If it is under warranty, sit down for a good hour, read BMW's policies and you will see you have no choice but to take what they give. This is agreed to by the buyer at time of purchase or warranty transfer. So arguing about this "reman" or "new" issue is pointless. Also the fact that there is a price difference between new and reman is simple logic, not a lesser quality justification. They do not have to supply a new block to start the build.

Why do you think there is a price difference when you buy a new motor versus a reman motor if you think they are identical?

The S65 is Alusil not Aluminum. BIG difference.

Not questioning you're knowledge but Alusil sounds Latin. What's the difference?

LOL, and I do not speak Latin! Alusil blocks contain about 20% silicon particles. When you bore and then hone Alusil(a very unique procedure) you expose tiny silicon beads that create the surface that the rings ride on(they do not touch Aluminum). The valleys between the beads get filled in with oil and ring material(during break in) creating a near perfect, frictionless seal. This is why the break in procedure is important as to how it is carried out. Hope this helps

Awesome! So how does overheating affect Alusil vs an aluminum block like the M54?

I do not have technical info as to the overheating aspect aside from the fact the heat KILLS a motor, period. I would have to say that Alusil would have a little more tolerance to heat as it is somewhat porous that could also help with dissipation. That being said, I would not use a severely overheated block.

Nope. Entire block. Nikasil was a coating but Alusil block is the entire block.

yes thats' interesting to know, but I still be hard pressed to believe that it's not "Alusil Aluminum" meaning the alusil is w/in the aluminum block

Wrong. Alusil is a finished product just like Aluminum. It is silicon mixed into Aluminum that gives you hypereutectic aluminum silicon alloy(Alusil). Alusil is an entire block and Lokasil is cylinder walls. Search some Porsche and Merc engine sites and you will find all the info you need. They have been using Alusil since the 60's.
