I realize you are just now going to put the engine back together. But, let it be noted that if you use silicone valve cover gaskets. They will bleed silicone into the oil giving the oil analysis people a higher reading of silicone in the oil. leaving them to think you are ingesting dirt.
Some time ago I sent a bottle of oil from an oil change and got an alert of a possible intake leak. Thought it was weird and called and after some questions we realized I had just replaced the valve cover gaskets with new silicone ones.
Blackstone said, Well now, there is your intake leak. ha ha ha.
No leak, But, silicone came down on the next oil change.
Yes I still have silicone gaskets.
Enjoy the ride Art
