Morris Minor Owners Club

hello ive got 2 spare engines as well as my orginal I was hopeing to build 1 out off the 3 the spare engines are gold seal engines I don't know iff they are all compattble the gold seal engine numbers are 8G126 R J26402 AD THE OTHER IS 8G163 R M 82393 A D can any body help thank you ,rae

Are the engines all the same eg 1098cc, 948cc ? The prefix 8G signifies that they are goldseal A series engines but the other numbers don't actually tell you anything about the engine size as they are just factory job numbers.

thats what idd like to know are they the same how do i find out ,rae

You look at the left side of the block - if it says '950' in the casting - there's a clue. Also take the rocker covers off and look at the head casting number - 12G202 is for a 1098 engine. There's always a vague chance that someone has fitted a 202 head to a 948 - but unlikely if everything is 'gold'.

so a 1098 would have 1098 cast on the block then is that how i tell its a 1098 ,rae

There's a pressed aluminium tab with '1100' on it by the crankcase breather pipe, but this could easily have fallen off by now.

is there anything else to look for ill take some photos and post them .rae

Pressed steel backplate on a 948. Cast one on a 1098.
Stock 948 manifold is squarer that the 1098 one.

Pressed steel plate on a 1098. Cast into the block on a 948 ITYM.

The 950 is the clue. If it's not there - it will be a 1098....simples! And the head number will confirm. The little stamped plate may not be present on gold seal units...... The HEAD is the give away...

948 is pressed steel

1098 is solid

They are not interchangeable with the standard gearboxes as the clutch won't have the correct clearance, but can be swapped over to facilitate a 1098 box on a 948 engine and vice versa.

However, as stated, only 948's have "950" cast into the block so this is the most obvious way of telling.

excellent thank you all 3 are 1098 so great I can hopefully build something on a budget now great forum help there will be lots more questions to come ,rae
