I just found somebody with crx with a 1.7 gsr swap in it but he has never got it running. Said his boy wrecked a gsr and his boy gave him motor because he owed him money. I dont think there is no internal damage engine bay looks clean. He said piston #4 is not firing what could be the cause of this? and the head gasket is leaking a little bit of oil what do you think this might be?
