as the title says , after i do a hard pull i get smoking out of my oil breather vents on my valve cover. its fine if im just cruising around but after a pull it smokes for a good 10 seconds like enough to come out from under the hood through he cowl.i got my passenger and driver side valve covers vented. whats going on and is there a fix to it?

 

So you have no vac on your crankcase at all?

 

nope,

 

that would be blow by......sounds like a catch can system is the next step

 

any boosted motor will move vapors but if you see puffing then you have issues

 

besides my trans slipping and over heating the truck is running strong. just after hard pulls it smokes pretty bad under the hood till where it comes out but only last a like 10 seconds after i come to a stop.

 

do a leak down test and that will tell you all you need to know

Only after hard pull I'm guessing you are building up crankcase vapors.
And those do take a moment to get out if venting naturally.
Blow by would be more inline if it's puffing out the valve cover just at idle or cruising.

All those crank vapors have to go some where.
