Before I'd do anything else would check accuracity of the oil guage--------------
Mechanical--condition of lines, fittings, etc
Electric------ground, ohms, temp, etc-------
OK , so I gave an opt for others to join in----------
rule of thumb is 10psi per 1000 rpm so your probably ok-------also change oil to thicker vis------ 10w30 is not a good choice for loose clearances and warm temps-------put 40 or 50 in and see if results changeLast edited by jerry clayton; 04-19-2020 at 05:00 PM.
