guy up the road from me just got a bobcat 450 and it smaller has a 18 hp opposed like what in the john deere 318s and it doesnt have any compression so what could be the prblem i have heard that there known to lose valve seat if over heated but i dont know any of the past history. Is there any common compression lose problems with these engine???

Probably an m18. Working on one of those right now. By no compression,you mean none at all or a low reading? Both cylinders? Kt's(which were the previous series ) were more likely to lose compression. Mostly rings went bad on them. You can try putting oil in the cylinders and then test compression. If it stays the same,the valves are at fault. If compression goes up,then the rings are at fault.
