b18a valve cover on b18b setup
 

currently running a b18b jrsc.. just got a b18a valve cover to have vents put in the front of it.. i want to now use my b18b valve cover instead for the vents..
the main difference between the two is the obd2 b18b valve cover has the pcv valve whereas the obd1 b18a does not..

does anyone see a problem with putting the b18a valve cover on my motor temporarily (like maybe a week) until the b18b one is done at the shop?

no it will not hurt you rmotor or anything for that fact...

They are interchangeable.
