im looking to buy a an 88 turbo II but the only problem is the guy says the one of the irons is cracked due to over boring and it is making coolant leak into the engine. how easy is this to fix and how much am i looking to spend? he is giving new irons with the car and says that the only things that need to be bought is coolant seals and a gasket kit. let me know

 

You mean over porting? Where exactly is it leaking from?

If it is a minor crack then it can be repaired with brazing or even by backfilling with epoxy. But a bit more information is needed to make a judgement (like a picture).
