found the oil pressure on mine at 80psi cold and crap hot-taken the plunger out and it is scored.
Cleaned it and where it fits into and repacked with Vaseline in grease gun(saves ****ing around)

now 40psi idle and 60psi 4000rpm but still have plunger issues.

As the tadpole will not touch the relief hole when letting oil past it should cure it-anyone experienced this
