PCV Vacuum Leak
He claims to have built his own 500hp engine and tuned it... Doubtful if he is this ignorant about a simple vacuum leak.
What he did is aded a metco breather without doing anything else to the PCV... He just intoduced outside air to an otherwise closed system...
You can use a breather but you cant have it both ways...
