Pretty sure other on here would be more qualified, but cannot understand if it's air! Perhaps tighten the rocker cover? What model and year is it??

2021 so 4 bolt covers. Pictures of where the suspected leak is would help. I am surprised it is air and not oil.

The original cork gaskets are just “one or two” use only and that is if you remove and replace very carefully. Of course it is crankcase gases……try a very cautious tighten and get new gaskets asap.

Not wanting to highjack the thread. Are silicon replacement gaskets available in Oz?

Many thanks Bruce. I started looking for nitrile sheet and in the process of finding some also noticed there is a 90 degree centigrade limit. I assume this is point at which the nitrile degrades. Have you seen this as an issue? I would think the head temperature would exceed this. I know silicone is 260c.

...also noticed there is a 90 degree centigrade limit. Checked this yesterday after a run over the range, the very edge of the head where it meets the gasket was 87 on the right and 80 on the left. The rocker covers were 70 and 60 close to the head on the underside. Both heads were well over 100 at the plug point. Disclaimer:- using a very cheap point and click thermal sensor.
