That looks terminal, I wonder if it has cracked into the crankcase as well which might explain the seized engine, One of the engines I bought for the minor looked fine from above but would not turn, look the sump off and the bottom of the bores and crankcase were full of rust, it had been stood with a loose sump plug and moisture must have got in.
I'd start looking a aj6 engines, an R supercharged one would be interesting..

That looks like a job for metal stitching, not the end of the world it will just take a little longer to sort out.
It's worth saving.

Anything is repairable if your pockets are deep enough, but that looks from here like it might be hard to justify the expense and aggravation. Especially given the potential for future headaches with the siamesed port design etc. and your plans for lpg.

Give it to goldnrust, cracked blocks are his speciality. Austin 3 litre might go in if you can find one. I have a spare bmc 1.8 diesel in my garage. Would be slow but would drive from dusk till dawn.

I have a 5.1 litre BMC sixpot diesel here too, but I suspect it might be a little lacking in the refinement department for you...

Nah, electric can go suck a kumara. I'm more inclined to agree with Mr Bravo. There's absolutely nothing wrong with a big diesel. If it sounds like a tractor that just adds to the charm.
edit; That noddy van engine might actually be worth a crack.

That looks like a job for metal stitching, not the end of the world it will just take a little longer to sort out. It's worth saving. You would be opening yourself up to a whole world of pain. It’s not ultra rare or ultra collectible. If money wasn’t an issue and it was ultra rare I would rather get a new block cast ,rather than try and repair that. Brave man who tries, as he would be married to it for the rest of his life....🙄 The forces acting on the stitching would be 90 degrees to the stitch when you torque the head down,so unlikely to be a lasting repair. Metal stitching does have its uses,but I don’t think a crack that long in the position that it is in,would be advisable 😊 |

Thanks Pete , today my Friend up the rd will have a look and see if he can braze or weld it . he has done it before with success . i will blowtorch the pistons a bit ,and maybe if i need to hoick the sump off and knock them out one by one , and see how the block cylinders look for cracks etc ...then make a judgement on it all . Ouch. I feel you pain on discovering that crack..... yup , we are members of the cracked block brotherhood .high 5 !  I have a 5.1 litre BMC sixpot diesel here too, but I suspect it might be a little lacking in the refinement department for you... errr ...no  you are right Glen , i want this to be as silent as possible , maybe a slight turbo or supercharger whine . but multitudes of silencers underneath . |

I wouldn't even bother with the original, the jag engine is vastly superior in almost every way, and there is even an off the shelf supercharger set up for it. Even if the crack was repaired I would always be worried about it going again.
You could have that jag engine / box in and running in a day!

Jag motor will be perfect. Who would even think about putting a noisy diesel in a refined car like this? It´s the exact opposite of what it needs.

I too think that the Jag engine you’ve already got is the best way forward. Could it be made to fit the RR autobox? If only to be able to keep that lovely column selector. Probably the ZF is a better bet though. You might even find that the AS’s bigger wheels and tyres, coupled with the Jag engine’s ability to sustain higher revs, means that the 4:1 rear diff isn’t so bad. My P4 had 15” wheels and a 3.9:1 rear axle.

Upset for you on the engine front but happy with possible alternative options.
I do think you may need a different ‘driving’ hat though. Perhaps a bowler or top hat for the evening.
If jag engine and gearbox go in the ‘sprint’ Gearing could be really quite entertaining anyway.
Carry on.

If you do fancy a diesel, then a whole e39 530d can be had for around £600 and they regularly fit them in old landrovers so all the loom etc is available from the facebook groups. They you could pilfer lots of other clever bits and the diff etc

Correct me if I’m wrong, but the ZF 22 autobox is overdriven in top isn’t it? 0.728:1? With 6.70 16 tyres, at 727mm dia, that would give you about 30mph/1000 rpm in top with the stock back axle, about 2400 rpm at 70mph, which sounds about ideal to me. Ashcroft Transmissions has a ratio calculator on their website: linky

The zf box has a single cable operated shift, I can't imagine it would be thst difficult to make it work with the column shift in the car.
