You are doing OK with English and better than me trying to speak your language. I already guessed you could freshen it up for about $500 bucks. To guess at prices I am pretty close but try looking it up at Jegs. Here is a link for you
http://www.jegs.com/webapp/wcs/store...10002_10175_-1 My guess at pricing is= Rings $100, gasket set $125, valve springs $75,
oil pump $50, rod and main bearings $130 and chemicals $50.
