Let the boy go !
With no PCV valve you will get sludge and carbon build up eventually. You need to vent out unspent gases or they settle back in the engine. JMO
I'll go ahead and ask since no one else will. Why were you running synthetic on a new engine? I was under the impression that you needed to run dino oil for at least a few oil changes before switching to synthetic (not that I ever would).With 10-30 synthetic there was no oil blowby after 600+ miles of driving
anyway point is you need to properly vent your system pcv is best and emissions compliant
