i recently bought a 98 warrior. Whe i got it it ran great for about 10-15 hours. After this 10-15 hours my valve guide stuck to my ex. valve shoving it into the head and bending my rocker arm. When i dissasembled the head i noticed that the cam lobes and rocker arms were wore beyond belief-obviously no oil . I bought a new head and installed only to find that i am still not getting oil pressure. I have tried everything that anyone has recommended trying and nothing has worked- Ireplaced pump(twice), tried different oil filters, ran without oil filter, tried to prime pump with lighter & heavier oil(also tried lubriplate grease), made sure all oil gallys are clear and am out of ideas. PLEASE HELP.

 

there must be a metal flake or something clogging the system somewhere...

 

Yeah..what Speedy said. Try checking all the oil passage ways to the head...if you can.
