Here are som photos, of the "Fat" one .

Its one of those engines with the BIG bore, and tappet covers, that can be removed, from the block.
It has too many studs&bolts to hold the head, no vacuum on the destributer.

And as the title indicates a "FAT" flange where you bolt it to the gearbox, which have driveshaft couplings,
that share first name with one part, of 2 famues American comedians .







Shame is was left in a garden for so many years Rolling Eyes (since 1978)

removed the head, it had 4 stuck valves, but I worked a little on it, so they would move again.




This is what I found, after the head was removed.





This is NOT what you want to see, when you remove your drain plug Crying or Very sad




Hardly any metal bits on the magnet, engine only done 3000 miles.

I must admit that I had the same thought after the initial description. 30 years in the garden!
I think the first thing I'd do is see if I could get any over-bore numbers off the piston crown & see if there's enough metal left to do it again. I think +40thou = 1340cc is the max possible.

If it's rare, a re sleeve would be an option. It is amazing what can be saved.

Hi all Smile


Thanks for the input/comments/advice.

The engine will be rebuilt, I paid money for it Rolling Eyes and I dont like to waste money Wink

worst case scenario, I will make it into a coffee table Wink

I will check the pistons later, and it its too scared in the bores, it will be resleeved.

Here is a picture of the drive shaft coupling/axle.

Hi Kelsham,

Well rare is sometimes hard to describe ? but its a genuine 1275 S, with all the correct bits.

Regards Jens Christian

I had my Morris 8 engine re-lined, it probably added a couple of hundred quid to the rebuild cost, a 100 or so for the liners and about the same for the additional machine shop costs. Small benefit was that standard sized pistons and rings tend to be cheaper and everyone wants oversize Very Happy

Cranks can be metal sprayed if there is not enough metal for a regrind.

Hi Dave,

Yes that sounds like a good option, and if I do, I might as well have the new liners bored out,
to fit the pistons in the engine (if they are OK?) as they have done so few miles.

Hi N,

yes I imagine you would like that Wink nah I think I will keep it Smile

I will buy a 1½ liter Coca Cola, and pour into the bores, to see what happens ?

Yes I know I need a car for it Rolling Eyes but that will probably never happen.

I have all the Gold brocade seats, 7.5" S disc brakes, correct LP 883 S rims, but no car Sad

Kels, I fully agree. I've been involved in engineering all of my working life and firmly believe that with enough determination almost any mechanical device can be made good. Eventually Rolling Eyes

An engine is only a bunch of castings containing some things that go round and round and others that go up and down.
