I bought this car with blown head gagskets , replaced them . Experienced low oil presure fault shortly after rebuild , put gage on and had 70 psi at idle . replaced sensor . shortly after low oil presure fault occurred again , this time no oil presure . found balance wheel bolt loose , tightened it, could not get oil presure , filled pump with vasaline to prime up . obatined 70 psi at idle . drove car 2 weeks . lost oil presure while driving. towed home, took pump apart. cannot see anything wrong . hooked clear plastic line on intake port of engine block and vacume easily sucks up oil , no blockage in screen . took oil filter casting off . passage clear to filter neither relief valve in punp or filter casting appear to be sticky. . put back together and have 70 psi at idle . drained oil out filled crankcase with diesel fuel . ran for 6 min. oil presure at 20 psi. changed oil and filter . presure at idle was 50 psi. 100 if reved up slightly.let engine cool . started up ,oil presure 80psi at idle. I am afraid of blowing the oil filter off , or losing oil presure altogether again. Any suggestions?
