How do you tell a 3 burrin from a 5 burrin.

I have a 2.25 petrol block, how can I tell if the cranks got 3 or 5 burrins.

Edit: oh yeah, without taking the sump off or the engine apart.

LOOK at the side of the engine under the manifold if its smooth -3bearing........... if its ribbed -5bearing ..simples my friend ,,hope this helps,,,,,dave

If you can see the original engine block colour 3 bearing are a pale bluey/greeny colour, 5 bearing are brown,

pretty sure its a 5 burrin as its broon.
I'll have a look when I get yam tonite.
Thanks chaps.

the engine numbers also help from 36100001A, 99100001A for petrol
and for diesel 36600001A

Well actually it turned out to be a 3 burrin, from the lack of reinforcing webs andthe engine number.
I've now sold it, he whole engine with all the ancilliaries for £110, I hope that I havent diddled myself or the bloke that bought it.
It was a good runner so the bloke who bought it didnt get a bad deal.
