E39 540iM6 Motor

[VivP]

Greetings again, all. raise:

Some might remember my previous posts mentioning that I need to rebuild the M62B44 non-vanos unit that is in my early '98 E39 540i.

Well, the unit has been removed and pulled apart. One of the barrels is completely stuffed. :bangdesk: :argh: Also broke a valve guide, got piston slap, hit a bearing .... :argh:

Apparently, nobody in the country can repair these "Alusil" liners.

And hereto my questions:
1. Can these blocks be repaired, and by whom at what cost?
2. Where can I get a decent donor aluminium/alusil block, and at what cost?
3. Where can I get a decent donor motor, and at what cost?

And lastly - I have a lead on a "complete power unit", but speaking to the fella on the phone, I'm not 100% convinced he knows exactly what he is selling. How can I easily identify the difference between a M62B44 and a M60B40? I think he might have the latter instead.

As usual, any and all comments and help is greatly appreciated.

Cheers :ty:

Some claim you can use steel liners in the alu block my own expereince with these is that they do not work and will fail before 30K km. The situation is complex as the pistons are steel coated, guys often reuse them and you cannot use steel/steel or alu/alu only steel/alu combinations for some reason

M60B40 has a dual row or dupelx timing chain and square cam covers.

M62B44 has a single or simplex cam chain and the cam covers are more tapered in shape especially at the front. Both chains are visible if you remove the oil filler cap.

Try Bruce's BMW in Capetown I remember he strips only good cars and ships country wide.
