Passenger side pcv delete help (searched)

Ok so I did a search and I know there is info about this but I can't seem to find how exactly its done. Does Anyone have pics of how they did it. I used a breather on the driver side but im not sure on the pass?? I know I could use an intake tube and adapt a fitting for the pcv but if I can delete it and not hurt anything I would rather do that and it will look cleaner. Do I just remove the pcv and put a breather in its place??? Pics would be great thanks in advance fellas.....

Yes, if you don't want and/or need the PCV valves you can put a breather in both valve covers. If you don't want to do that though you can just find some way to attach it to air intake somewhere, doesn't matter where as long as your before the turbo and doesn't matter how as long as it's secure.

Correct me if im wrong but on the passenger side valve cover it looks like the hose T's off. One runs to towards the front of the engine to pcv and I cant see where the other goes. Im still learning about our trucks so bear with me...

Of course, no worries we were all there once. It does T off and goes back and connects to the throttle body, and the front goes to the crossover.

Ok so if I can put a breather on both valve covers what do I do with the the hose that runs to the Throttle body?? Do I block it off or ?????

if you are removing the t- stuff on the Passenger valve cover Id like to buy it

I would question what your goal is in removing it? It does serve a function and it is more than an emission requirement.

I never knew that it mattered, what does it effect?

The same isn't true for the drivers, is it?

Yep, pull your PCV off and when your engine starts to leak oil wonder why.

PCV is somewhat misleading, as it really is there to PREVENT positive crankcase pressure. Pressure always escapes through/past the rings during combustion. That pressure ends up in the oil crankcase. It has to be vented somehow, just having a breather often is not enough and forms to "suck" it out are needed, hence why the factories came up with a PCV. They use vacuum from another part of the engine to suck it out.

Turbo motors with higher compressions and "blow by" make things even worse. Go look at the really fast guys with boosted motors. They spend a lot of money and are willing to sacrifice money by installing vacuum pumps. Well beyond even what a PCV valve does. It comes to reason they are willing to give up 20+hp to turn a $1k vacuum pump ONLY if they will gain more than 20hp or they have some benefit. Otherwise they would run $10 breathers also.

I have gone to length with my own ty, I have 2 larger breather tanks one for each valve cover. I have still had pressure issues and have debated about some form of vacuum.

Not saying PCV is the best way, just before you guys start ripping parts off you might want to understand why they are there.

Thanks Ken and Jeff, never knew that, both my trucks already came with breathers, I just figured it was fine. I guess that mindset is as bad as if it came with a KB chip.

Either way mines going back to stock just to pass visual emissions testing.

Re: Passenger side pcv delete help (searched)

Ok so after some tinkering I got everything working right and I ended up keeping the pass side pcv. I was able to drill a hole in the intake and used the fitting from the stock crossover tube. Hey pancakes sorry I wasnt able to sell you that stuff and thanks for the reminder that the pcv is dealer only I almost bought one from advance auto just now... Thanks again everyone

Not true. I have a pack of about 20 I got from gmpartsdirect. Needs the little E on the bottom but they're not dealer only.

Proper PCV is required, not only to remove the moisture and pressure, but to help pull fuel vapors that collect in the crankcase, which dillutes the oil over time. I have replaced more than a handful of front and rear main seals that have blown out due to frozen PCV valves, so the possibility of seal failure is real enough.

When you are under boost, the PCV valve is closed to help prevent pressurization of the crankcase. This leaves the vents as the only way to relieve crankcase pressure. On the typical closed systems, there is a slight vacuum in the intake tract to help evacuate the gases into the intake (prior to the throttlebody-not manifold vacuum). This tends to coat the throttlebody plates, intake and back of the intake valves. Really bad blowby through the intake also reduces the octane rating of your fuel, increasing detonation thresholds.

If crankcase pressure under boost is a problem, running improved venting is necessary if you aren't going to add a vacuum pump. Putting vacuum pumps on allows for a negative pressure to be applied to the crankcase during boost, helping to evacuate the system much better than just through a vent.

If you are interested in the crankcase pressure, you can always plumb a pressure sensor (even a MAP sensor) onto the dipstick or such to measure any buildup.

The PCV is special for the syty due to boost, so under boost 1 closes off and the other hooked to the intake tract pulls some. Hence why we have 2 PCV valves.
