After a long summer, I started back on the mini.

 

Did some rust repairs on the sills, and my engine came back from the machine shop. Had to bore the cilinder walls because of too much play, oversize pistons it is

For the rest everything is sended out for powdercoating.

Congratulations on getting the mini going again!

I'll be sure to follow your progress!

I have not seen a mini torn apart before - I do not have minis anywhere close to me at all!

-  Can you please show me what the structure is like behind the outer sill (the part painted in silver with the vents? - (in the picture below).

I am curious about what the space behind the sill vents look like?
Is there somewhat of an empty 'tunnel' there between the sill and the floor - Is this correct?

Is the first and second pictures in your post above looking at this area without the piece with the vents?

I've been thinking of spraying some lanolin based wax product into that space through the vents to coat that area and ensure moisture is kept away. I definitely find myself in dry weather - but just to make sure that enclosed space has a barrier against any moisture...

I imagine there is nothing in there that I can damage...

- Any thoughts from others on this? I'm sure many of you are very familiar with this part of a mini, I've never had access to this part in a mini!
And I have not found  much insight into this void in any diagram I've seen.

The first two pictures are the inside of the sills. This can be sprayed with wax of you don't see any rust on the outside or the inside. Then the sill has gone too far. 

 

There are no parts that can be damaged by spraying wax inside of the sill.

this isn't accurate to scale but it shows the basic layout

 

 

black, floor pan inc inner sill (one large piece)

green, door step

orange, outer sill

yellow squiggle is the void between them

 

the orange bit can be vented as you can see in the pics above which lets it breathe and drain out

 

I painted mine inside with waxoil based underseal which did mean I got a few whiffs of smoke when I plug welded it together, I also plan to waxoil as mentioned above

 

the outer sills are quite cheap and the work involved is relatively minimal.  it is a bit of a rust trap so with pretty much any old mini you'll want to take them off and inspect underneath if there's any amount of rebuilding going on

 

(apologies for jumping in on OP's thread but it seemed relevant)

Thank you @Siaugary

Excellent news! - I do not see any signs of rust, but coating it in wax - especially since it is an enclosed space - should ensure it stays protected.

Thank you @stewart Bowes. It seems the image would be helpful! BUT I cannot see your picture! (The link destination asks me to upload images). Can you please upload via the "more reply options" button at the bottom of the text box?

And apologies also from me on the thread distraction!

That's odd yes if you follow the link it will just take you to imgbb but the picture should be visible just in the post

I'm looking at it now and it's there

For me the picture is visible. And a good representation of the sills 

[siaugary]

Picked up all the powdercoated parts today.
This would be everything for the subframe And suspension. Also Some engine parts.

Yesterday I started my work On the engine And it seems that I bought the wrong main bearings.
Wich ones would I need. I assume it is An a series engine. 98h with tapper covers?

Well, magically, today the link is gone and the diagram is there in all its glory!

Thank you for that! This and the description is very helpful!

There are two distinct main bearing designs: 8G2177 bearings have a crankshaft journal width of 1.192" (30.28mm), whereas 8G2332 bearings have a width of 

1.067" (27.1mm).  The wider 8G2177 type fit 848cc engines built between 1959 and 1969 (engine number prefixes 8A, 8MB, 8AM, 8AH, 8AJ, 8AK, 8WR),  

whereas 8G2332 bearings fit all 997cc engines, plus 848cc engines built from 1969 onwards (engine number prefix 85H).

 

 

Internal engine - 848 and 997cc : Somerford Mini - Mini Specialists, Pro...

 

Measure the old bearings.

 

(I have a 1971 with 85H engine but it's still has the wider bearings so nothing can be sure   )

the widht and diameter of the bearings are good. It is just the notch on the main cap that is off centre.

I see.

 

The notch should be off-centre on both halves as far as I  know

 

Where did you ordered yours and what is the part number ?

 

I ordered a set from Somerford and it fits to the engine

The serial number of my engine is 99H791PZ 446365

I think I have ordered the bearings for an A+ engine and this would be an A series.

 

the bearings are AEM3427-00

[gaspen]

Yes it looks this is the issue here.

 

I thought that it is a real 850 engine but now I see you restore a 998

I do not have the original engine
