Engine Compression

Hi No compression in cylinder one, added spoonful of oil in to cylinder 1 still no compression, no blue smoke from exhaust pipe when fired up, hardly runs though! cylinders two, three and four are reading approx 145, engine is the N12 1.4cc with approx 90k on the clock, removed valve cover found top chain guide broken no sign of plastic guide, valves appear ok just looking from top not sure about seats etc. Do you think its just the timing out causing the no compression or deeper trouble with valves , seats , guides etc.

Regards
Kevin
