Here are 3 pictures of my main bearings state, would you change them ?







Same with conrods bearings, would you change them ?

There are some small "pitchs" but that's just dust.

I am going for 350+ bhp and don't wanna end up rebuilding the engine. Problem is I've already weight matched the rods/pistons, so changing the bearings would mean I have to re-weight all again. Ok if it can save a full rebuild I will change everything, but don't wanna change something which would be useless to change.

Advices welcome !

 

Without ANY shadow of doubt.

You should have seen the ones I threw away recently, they looked LOADS better than that.

 

Every time I take an engine apart they get changed. Not worth risking re-using them for the cost of new ones. The price of a set of bearings could save you the price of an engine rebuild.

 

For the price - YES.

 

Ok lads, I will change everything then. I wasn't sure if it was really needed, but yes, considering the cost of a full engine rebuild after a bearing failure, its not worth the risk !

Thanks !

 

look fooked to me.........hope you have looked at the crank aswell.......

 

while its apart i would ALWAYS change them as a matter of course.

they are pretty cheap considering how vital they are

 

make sure you clean all that rust off too..........

 

When an engine is disassembled all the consumable parts must be changed simple as that...
