I have done a search and I'm not sure which driverside valve cover breather will fit the stub that is in there now when you pull the boot hose off. Do I get a 62-1020 or 62-1340 K&N? I have also seen where some have used a Mr. Gasket #2049. Which one is the way to go and will complement my passengerside Ford motorsport breather... thanks Jeff

 

Why do you want to put a breather on the drivers side when you already have one?

 

Sal since there seems to be allot of crankcase vapors I thought 2 vents would be better than one. Maybe my theory is not correct....don't know. Jeff

 

Ok, just curious, wanted to make sure you knew that you didn't HAVE to vent the drivers side, because the valve covers are connected by the crankcase
