Details! They make the difference. You need to know how it works when all is normal to know what to do when it doesn't. This oil pressure relief set goes all the way back to early Beetle days when so many high performance places were selling the oil pressure boost relief springs and plungers. Let's twist some pump shafts and blow up coolers! Dennis

This is dependent upon spring length and tension. Weather the released spring length is 60 or 62.5 mm is not going to make a significant difference. Depending on the oil pressure switch used the oil light flickering at low speed or idle is indication that the oil pressure has dropped below 3 to 5 psi. So whether the relief spring is working at 30 or 40 or 50 psi it just doesn't matter. So a new spring is not going to fix anything.
