If you reduced the diameter of the adjusting bolt to fit within the spring by 1/4" depth it would center the spring and allow the use of the original spring. That way in addition to the drilled and tapped retainer fitting you would just need a socket headed bolt and the leak proof nut. If a person supplied the modified adjusting bolt and special sealing nut the customer could have the spring retainer fitting drilled and threaded and be in business. SKeown

Do you wonder what it does to the oil filter bypass operation?

The filter bypass works on pressure drop across the filter. If you're dumping less flow over the relief, there is more flow going through the filter and into the engine so the filter bypass may open sooner if pressure drop through the filter is higher than the filter bypass opening pressure, e.g. cold oil or high flows.
A wise person may fit a filter that has a higher flow capacity, built-in bypass with higher opening pressure and plug the stock one. Those who understand that filtration systems are designed to keep the oil in the pan clean through multiple passes through the filter likely aren't alarmed by the bypass opening. Those who are concerned about maybe catching debris in the filter when the engine is failing and if lucky, reducing downstream damage might be ... but if the filter is plugged and bypass doesn't open, you get no oil to the engine. Do you wonder what a midplate with a hole too small for full relief flow does to the filter bypass operation? |

Ask Rebel Machine, or refer to his Take 6 thread. 85psi with the midplate and no relief valve and 0psi with no midplate and no relief valve certainly seems to indicate the hole size is a bit restrictive ... at least on the one he installed?

There's nothing more exhilarating than paying mega $$ for unneeded gegos!! How's that for a motto Matt?? Or maybe "We're the AMC enthusiast best friend!!". SKeown |

I drilled and tapped the factory spring retainer for 7/16 and installed a bolt, washer and nut to lock the bolt after adjusting. I used liquid teflon on the bolt threads.and it stayed dry. This was with a factory length spring. The first attempt was with a 3/8 bolt but it wanted to thread into the spring so I went up 7/16 and it pushed on the spring without binding. |

Well now, that's simple. What was your experience with adjustments? Pressure before and after? Etc?

When turning the bolt it gets to a point where the pressue takes a jump quick. That is the zone where you tune in the pressue.
You can pretty much make any pressure you want with it and blow out an oil filter if you want to do that as well.
