Any trouble with17 HRS upper head gasket leaks

I've got a 2017 RG special that started leaking oil from the front upper cylinder head with 12k miles any thoughts on cause. Looks like teardown and inspection are in order. Please advise.

I seem to recall something with 2017 rocker boxes leaking. The MoCo made a running change to the gasket IIRC.

And people are finding burned out head gaskets on the 107's. Usually the rear jug on motors with oil cooling.

Do be sure to nail down the location, before you tear it apart.

I have had 3 stock 107s in the last 3 months with bad front head gaskets. They were all 2017s and all oil cooled. I think it was a bad batch of gaskets more than anything. The ones I have torn down, nothing abnormal was found and nothing was damaged. (Other than the bad head gasket) Haven’t seen it be an issue on very late production 17s or any newer ones.
