worn rings, get a can of RESTORE, add it when you change oil. Replace one quart of oil when you change for the can of restore. The restore will help reseat the rings and hopefully reseal them to stop the blow by unless the rings are too far gone........and change out the PCV valve if you haven't. most blowback is caused by broken rings, not worn rings. adding any chemical only masks a problem and will just lead to a more expensive repair at a not to distanyt future

What is blow down pressure of safety valve?
the blowback or blowdown of the safety valve is at least 2 psi and for pressures over 100 psig is 2% of the popping pressure. The blowback is adjusted with the adjusting ring on the safety valve. The blowback is the pressure less than the popping pressure at which the safety valve will reset. Examples: a safety valve set to pop at 15 psig will reseat at 13 psig, the blowback is 2 psi. A safety valve set to pop at 250 psig will reseat at 245 psig the blowback is 5 psi or 2%.
