This compounded by the 4age's natural tendancy to drop oil pressure under cornering is a concern. It's kind of similar to the b20 problem but its not a for sure thing. There are plenty fo people who run fine like this without problems, perhaps they used a shitty oil pump when it popped or didnt check the oil. Who knows. But im just taking a little bit more time to make sure, so ill port the pump and shim the spring just to be on the safe side of things. I'm also goign to consider putting in those gze oil squirters, but I want to check with engine builders first. You have to clearance the crank since the bump into the squirters, and I dont really want to take a grinder to the crank lol. I have to find out how much it will cost to machine my crank a bit properlly.
