For whatever it's worth Melling lists 2 pumps for that engine M295 and M295HV. The HV pump flows 18% more oil and is recommended for high mileage vehicles to quiet valve train noise. Might try that before you tear into doing lifters etc not saying it will solve your problems but a lot easier than pulling the intake etc---Fed 387
