here's a couple of photos that show why Toyota went to a 42mm big end journal in the 100 kw engine.

 

this engine has only 160,000 km's on it and it wasn't driven hard?

Man thats crazy, Who's motor is that?

came out of a blue MR2, i think you know who the owner is!!!

Aah, I thought mr2's all had the bigger cranks..

No, Might be a 7 rib block but small internals, That 4age i had with the holes in the pistons was a 7rib block with small internals and no oil squirter's.

I was under the impression all 7 rib blocks had the big crank, oil squirters or not..

it's a very early MR2, this one was made in 1984. and it's an auto.

 

call around and see Tony sometime, he'll tell you all about it.

Mine was from an MR2 but I'm not sure on the year but most likely an early one as well.

Was over that way today, Should have called in..

 

Will go see him at some stage, Just need time, Last time I went with Teddy we got stuck chatting for ages, lol...

Does it have a 200mm clutch too?

what power and what revs did it let go at?

he was driving home from work and it just started making noises, it's just a standard 86kw 4AGE 84 MR2 auto.

hasn't been played with at all!!! :lolcry:

 

rev's would have been under 4 grand, easy.

It doesnt look like its been oiled to well.

yeah i'd say no oil / low / shit oil

but omg that some serious dammage

if it had a oil problem it would have run a bearing not snaped the crank. the oil level was full, pressure was oil & it had not long ago had a oil change. i think the crank had fault in it. all the other bearings look overrated except for the middle main which supplys that big end bearing, it looked like it had run low on oil, but still wasn't bad.
