the future for 197 owners??

[bloke]

4th crank i've pulled out inside a year that's cracked across the big end journal!! no blueing to the rod and minimal on the side of the shell.

sorry pic isn't the best.

not good

 

[197.]

I'd be surprised if the rest of the car lasts long enough for the engine to be a problem tbh

What’s the mileage?

Has the crack marked the bearings, or is there a chance the crack would go unnoticed - if the engine wasn’t pulled apart?

Was meant to of been a low mileage engine, came out for a boost conversion.

Crack wasn't there before it picked up on the bearing. Was the one thing I checked for before I even thought about using the crank.

If you weren't looking for the crack it's very easy to miss. Forst one I had wasn't spotted until after the crank had been polished.
