Engine Identification

[adritch]

Slight repeat of a post I have under general discussion, except now I'm not sure my ebay purchased alledged 1098 is in fact a 1098.

Engine number is 10V/189E/L92866.

Can any of you learned folks shed any light on what size engine I have?

Thanks,
Adam.

The 1098 should have a plate reading 1100 low down on the front left of the engine ;)

You have a late (after March 1969) 1098cc engine, LOW compression, with a dynamo originally fitted.

Ok found the following site;

http://home.zonnet.nl/carclub.ij-v5/MG_ ... necode.pdf

which is quite useful info wise, though still not sure I fully understand all the numbers, but:

10V indicates - Morris 1000 van closed circuit breather (what's the end bit of that mean then?)

Don't know about the 189E

L - think this is low compression (booooooo)

Don't know what 92866 means (expect this is just the engine number).

Anyone corroborate by view, or tell me the bits I don't know?

Thanks,
Adam.

It all fits ok, you have the low compression engine which is usual for the van, the 10V 189 E is the proper prefix for post March 1969 engines and
yes, the number is just the engine number. The L denotes low compression. Closed circuit breathing means that the crankcase fumes
should be fed into the CARB (not the air filter) via a rubber pipe.

Thanks Willie,

What's the difference in power/torque between the high and low compression engines?

[Willie]

The difference between the High and Low 1098cc engines is purely in the amount of dish in the pistons. The dizzy advance curve is also different.
the compressions are: 8.5-1 and 7.5-1. Bhp of the high comp. is 48 @
5100revs. Maximum torque is 60 ft lbs at 2500 revs. I have no other info on the low compression engines.
