hi i got a s2 rs and my big end bearings i think are on the way out is it a big job can i do them with the engine in

 

could turn out to be a big job yeh

 

can it be done in the car tho or it better to take it out

 

btt

 

Yes just drop the sump

 

you can do it with the engine in... you would need to just remove the exhaust, thats about it.. well take the sump off of course,
BUT... if your big-ends are on their way.... just simply changing the wont help and you may open a big ole can of worms by doing this.. my advice be take the wole thing out, which is not a masive job really and get it done on the bench..
if your rings are ok ect and your main bearings are ok... you may do well to change the oil pump for a OE item whilst you are taking it apart..
goodluck
