If the wrong PCV valve is installed will it cause the truck to smoke? (1 Viewer)

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

it does not make any sense to me that the valve would cause this. unless it is much more restrictive than the one you removed.

What else did you do in your tune up?

And what color smoke?
