2000 miles in the crankcase? wow, thats alot... i drove about 150 miles with it in the crank case and then changed it
but yes, the PVC valve is where i did it also, 1st time i just let it keep running after i added it and burned the first dose out that way, the second time i choked the motor out with it and let it sit for a half hour and blew plumes of smoke, 3rd time i let it sit overnight and wow... it was really thick smoke
this is the PCV valve and the side you pour it in, just pull that hose up and pour it right down that, but not too fast, and keep a finger over it when you arent pouring otherwise your engine stalls
