Based on the collective evidence, the evidence strongly suggests prioritizing steel or high-grade aluminum camshaft plugs from reputable manufacturers known for rigorous quality control. While rubber options may offer initial cost savings, their susceptibility to degradation and potential for leakage necessitates more frequent replacement. Investing in a higher quality metal plug with a proven track record of durability and a secure sealing mechanism offers a more reliable and cost-effective long-term solution for maintaining engine health and preventing costly repairs.
