Just inserted a rebuilt 360 into my 75 Jeep Cherokee. Started up great; except oil jets out of the top of the oil filter at the rate of about a pint a second. My suspicion is that the oil pressure relief valve is not opening. What accentuates my suspicion is that the previous build did not have the valve installed...there was just a spring in the sleeve where the valve goes.
Is this a known issue? Is it common to not install the bypass valve? Or, is there something wrong with the cylinder in my oil pump where the bypass valve sits? Or do you think there's something else wrong entirely?
Any help is greatly appreciated. Cheers
