Far superior to the OEM gasket which is crazy thin and doesnt seal worth a crap. But remember that due to its thickness, your oil reading will be slightly lower than actual.

This looks like it really will solve the paper gasket hardening/leaking issue was hard to determine the proper torque. But no leak after 15 hours flight time

Happy with the product. One thing to consider after installation, the oil level on the dipstick May show slightly lower (1/16th of an inch or so) than actual. Not a big deal and you definitely won’t have any oil leakage after using this

Seems to be a much tighter fit and appears to be far more stout than a regular gasket.

Q: Regarding the complaints that the gasket is too soft ... when installing the silicone gasket (RG-72059) all surfaces must be TOTALLY clean and oil free, otherwise yes, the gasket will squish out ... same as their rocker cover gaskets. A&P-IA
