If the wrong PCV valve is installed will it cause the truck to smoke?

Hello,
I went to do a tune up on the plow truck yesterday, and I used all OEM Toyota parts. Well the PCV valve that Toyota gave me for my 79 20 r 4x4 looked larger than the one in the truck, but it still fit. Well the truck seemed to run great yesterday. Well today when I went to start it, it started perfectly, but when it was warmed up, and it hit the gas a few times, it started t o smoke. At idle there was no smoke, but whne you hit the gas it smoked, like white/blue smoke. What gives? The truck only has 37,000 miles on it. Could the PCV valve make the truck do this? I think I might have the wqrong one.

Thanks,
Zack
