I have a 98 warrior that i just rebuilt, new piston, valves, cam, rocker arms, and i got it all put back together last night and fired it up and the damn thing blew the bottom head gasket right when it fired, right side and the front. I have no idea why, but then i got it running and it just purred oil from the front, Any help would be greatly apreciated.

 

If the gasket did not break and still can be used (or if you need a new one) then get some gasket sealer and put some on. Tourque it down, and wait for the amount of time it says to. If it blows out again then get another gasket and buy some "idian head". Thats the toughest sealant known to man.
