That sounds like the oil pump pressure relief valve malfunctioning, not the filter bypass valve.Those engine internal bypasses are usually a very high PSI to active...I've seen one stuck in a jet ski and it would blow the o-ring off the oil filter at anything over idle, everything was fine after the bypass was replaced.
Could still damage the filter doing that because the oil pump pressure relief valve doesn't control the dP across the filter media and center tube. Only the filter bypass valve does that. Too much dP inside the filter can implode the media and center tube. One main reason the filter bypass exists is to prevent filter damage when the dP gets too high.Back in the 70s & 80s, with our drag race chevy engines, we would drill, tap, and plug the bypass in the oil filter to engine block adapter, and run a oil filter with no bypass. But the oil pump had a bypass.
Neither is good……but dirty oil is better than no oil. That’s the reason for the redundancyAnd I say oil filtered through a rock catcher is better than unfiltered bypassed oil.
Why were guys doing that modification thinking it was a "good thing" to do? Some guys probably damaged or lost engines doing that when the oil filter imploded from high dP, causing the oil pump to spike to pressure relief and possible media going into the oiling system causing oil starvation to the engine.Back in the 70s & 80s, with our drag race chevy engines, we would drill, tap, and plug the bypass in the oil filter to engine block adapter, and run a oil filter with no bypass.

Yeah, that is what I'm talking about...thought that was what the OP was referencing?That sounds like the oil pump pressure relief valve malfunctioning, not the filter bypass valve.
He's talking about the oil filter bypass in the engine block, like a lot of GM built engines have. That's not the same bypass as the oil pump pressure relief/bypass valve.Yeah, that is what I'm talking about...thought that was what the OP was referencing?
Ole chevys have great oiling, so we got away with itWhy were guys doing that modification thinking it was a "good thing" to do?
