you all are missing the point. The old seals are very easy to open and reseal, with no evidence of it happening. The new seals are much harder to do that. Yes, the new seals can be opened up, and resealed. However, when this is done, it messes up the anodizing and is detectable upon inspection. Phase 1 of the engine "fix" is getting rid of all old seals. Phase 2, will be implementing a protest rule for seals. This rule will likely be the tech official cuts of the existing front engine seal, and reseals with a new, different color/type/etc... seal. The old seal will be sent to USLC and checked for evidence of tampering. If it is suspected to have been tampered with, then the side seal will also be taken and checked in the same manner. If this is also found to be tampered with, then the engine will be taken and shipped to USLC.
Of course, this is the basic idea, and process will likely change, but you get the idea.
This keeps the tech guy honest, because he never has a full set of seals at 1 time, and it allows for a fair method of protest that doesn't stop a competitor from racing because his engine was protested and taken to USLC just to check...
