I'm still calling bs. For someone who is known for long drawn out posts doesn't seam like
much explanation to me, just a bunch of claimed instences. I run a kiggly regulator now anyway so I should be good.
I'm not trying to come off as a jerk I guess just give more details as to what happened if your making these kinda claims.

I do agree with you but I will say my car has actually snapped a rocker right in half too and could only point to a missed shift and had no other explanation at the time so this seems like a second option it could be. It was like a week or two after I bought the car and it sounded Identical to an exhaust leak so I drove it around for a month till I got around to getting gaskets etc. Finally pulled the VC and found the #1 cyl exh rocker laying next to one of my head studs. I got pics if youre interested of the whole teardown and I think some of the broken rocker. and found the other smaller piece in the oil pan.

You can find it on DSM forums. The front case is the same. Basically just enlarge the hole without uncovering the part of the piston that seals the oil passage, or it will leak pressure when it's not supposed to.

That's something you'll have to expirement with. I think @Dallas J came up with a different spring to use.

My 1992 DSM handbook included a warning advising the use of a high quality oil filter in order to avoid bursting the oil filter cannister. It didn't say anything about breaking rockers. So, I'm sceptical about that. If it was a problem I think it would be fixed by the time the Evo 8 came along.
Doing the extra pumping is robbing HP. What else is bad about high oil pressure?

The high oil pressure means there is less oil in the pan, where it belongs to prevent starvation. The system is designed to run balance shafts, when you don't run balance shafts, those 3 or 4 ports get blocked off and pressure goes up past where it should be. Porting the bypass helps with this.
Higher oil pressure also makes more heat.

Similar to turning the boost up on the stock turbo. More boost doesn't mean less flow, or the car wouldn't make more power...
