Oh and we haven’t found the culprit for the silicon. That’s been a mystery. As mentioned in that post air filters didn’t change the outcome. The trunk is tight and sealed as well.@thejudges69 can you re-shim the oil pump to drop your oil pressure a little. I wonder if the oil pressure is contributing to the shearing.
I’m with @56Cummins if you can’t resolve the shearing then I’d use the Mystik 15w50. I’ve got their 15w40 in my Cummins Ram currently.
On the silicone side I’m with Blackstone. Have you checked your air intake hoses? Have you switched air filters.
Just my $0.02
