standard 1098 engine
found an un-reconditioned mg block with a nice crank and con rods but a couple of dings at top of cylinder 1...(pic attached, sorry bit out of focus) this kind of thing fixable? Or not worth the bother?

Re: standard 1098 engine
Most things are fixable - at a price.
Rather depends on a few more details - and the price, of course.

Re: standard 1098 engine
It may be inside of the gasket seating area. Have you got one to place on the block to see?

Crosses the gasket line on the left. I think it's prob. junk but I might get a machine to look at a few pictures.King Kenny wrote: ↑Tue Mar 26, 2024 6:46 pm It may be inside of the gasket seating area. Have you got one to place on the block to see?
Re: standard 1098 engine
Wonder how it happened? How do folk go on when pocketing the block with the HG?

Re: standard 1098 engine
Cheers, I'll chase that up with the machine shop, lucky enough to have one fairly nearby. It may make sense to find a better block...but if they think lining it is a good option I'd be happy with that. I can use the crank/rods in either case.

Re: standard 1098 engine
Only if the distance between the extreme edges of the damage is less than 2.64125" diameter would you be able to fit a cylinder liner.
See section AAA.12 of Morris Minor 1000 workshop manual AKD 530.
If the damage distance is more than that quoted above the remaining damage will still be exposed and may cause problems. Even skimming the top of the block to remove damage and align the top edge of top the liner with the surface of the block may not be enough.
Personally I would ditch the block and find another in useable condition.
Purchasing another block may well be cheaper than purchasing a liner and having the machining done.
Here is a 1098cc short engine with a low start price of £35.
It may be rusty but well worth a punt.

Re: standard 1098 engine
We're on 2.71 so that's settled it...it can help weigh down the edge of my shed roof which catches the gales. There's one up there already The machine shop has a couple I think so I'll buy one off him.

Re: standard 1098 engine
If it's a MG engine does it have the larger 2" mains? if so it won't be so easy or cheap to replace.

Re: standard 1098 engine
No it's a 10CG so very similar to the minor 1100 engine, early midgets had them. There are a few differences, most obviously a mechanical fuel pump (but it's possible some moggies had this? Don't know). Still looking for a 10CC engine with 2" mains but that's my next project It's a much rarer engine and many of them have been raced to death.
But the latest is that my nearby machine shop has actually suggested that they could use a top-hat liner that gets around having to deck the block (which I would have thought would have messed up compression anyway). Never heard of this but what I don't know about engine machining would fill a thick and pretty comprehensive tome on the subject. If this idea works it'll save the un-rebored block and I can use the it's crank also...cross fingers
