I assume you mean the "plug", round and flat with the metal ring around the underside mounting area. No I have not experienced your problem in any of the 3 times I have changed the oil in both of my mowers. Hopefully you are using new parts to replace both plugs when you are putting everything back together.
I'm talking about the oil filler cap (part #15, sealing cap 30) located under the Pulley. It's a press-in cap. I was told by the Tufftorq service technician that I can reuse it. My point is that when I try to press the cap down flush with the case, it pops back up slightly and doesn't seal. I don't understand why the pressure under the cap is not released by the vent valve when I press down the cap.
