If your sure its just the rubber valve seals not the rings, thats a cheap job relatively
Has it happened in your experience, or is it only an IMO?
I think I've read that was only a myth.
What was a myth? Seal swellers? Conditioners? Explain
In the M1 HM FAQ seal "swellers" are mentioned. In the official Product Data Sheet the word "Seal Conditioner" is used. All brands seem to be intentionally unclear how they do it.
I think seal swellers ARE used. My experience using this oil on the Camry in my sig:
Symptoms:
Bad valve seals, blue smoke at startup, excessive oil consumption. Oil pan, valve cover leaks.
Results:
First M1 HM OC - no difference in oil consumption or leaks. Likely why many people bail. Second OC - WOW, no leaks, oil consumption went down to almost nothing. Took about 10k to see results, and they were dramatic.
decided to go off M1 HM and experimented with straight M1 5w30, even M1 0w20. As before, the first OC was fine, the second OC was awful, the leaking and oil consumption came back even worse.
Went back on the M1 HM again, first OC was bad, second good again. Now I'm staying on it.
So in summary I think there was a delay in effectiveness while the seals "swelled". If it were conditioning alone it should be more permanent, not go away so fast?
