PCV system

OK who is the PCV God?? It would seem that a standard vent cap would meet the rewuirment of releasing the crankcase build up and prevent back pressure and blow out but if nit them what does that little PCV do with the Vac and how does it prevent it from backing up is just with the Vac it sucks out the pressure? I am not worried about emissions at all but I dont want any blow by so what is my best bet. i have the Mopar Alum Valve covers so to do anything other than a vent cap i will have to drill so talk to me.

If you are talking about the black mopar alum covers you don't need to drill. If you take a ball peen hammer and give the knock out area few firm taps it pops out. You may have to take a small file and clean it up a bit. On mine on the passenger side I have a KN breather that fits right into the cap hole. Than on the drivers side I have the oil cap and PCV valve.
 
OK Mopardude

I will give it a try, but if I FXXX up the $130 Valve covers Im going to be pissed :twisted: I think i am going to look at that Mopar brather set cap and them a PCV .
 
pcv is not a bad thing, just dont plug it into a intake vacuum port "only"plug it into the carb,otherwize you will be giving 1 or 2 cylinders more of a mixture than the rest.on the street run the pcv, you will not get that oil/ fuel smell that comes from running open breathers.if you hooked up the pcv and the car ran worse, you are probrably running too rich (fuel) of a mixture...the pcv will add blow by gasses to the mixture which will cause richening of the mixture....no mater what anyone does pcv or not make sure you have atleast 2 breathers, or a pcv and at least one breather or you will have high crankcase pressure. think of a gas can...pour the gas out of the filler on the can and it goes slow and gargles (breathes)...then open the vent and it flows faster and un disturbed......just my .02

You paid $130 for the black ones? You got ripped. I paid $80 for mine from my dealer.

Well I am not saying my way is the best way. But a mopar guy who knows much more about cars than I will prolly ever know showed me that trick. A few firm taps is all it took me you don't have to bash on them. If you turn the cover over and look at it you can see its domed out in the center and thin on the edges.

do you have stock heads?
did you get the 383/440 covers, or did you get the valve covers for the 92+ magnum V8?
 
I dont have black ones I have the polished Alum MOPAR set look like this

so I will give it a try. i am going to order a mopar breather cap for on of the oil fill holes and then put in a pcv just to make sure so that should cover it dont yall think.
 
Those are nice! I think I like those better than my black ones. I see you have excellent choice intakes also. Both my 360's are sporting Air gaps also. If you going show off a pic like that you are going to have to list the specs of it too!

yup they sure do!LOL i tryind to put the LA's on my 360 ram and thats a no no so i bought the truck her own pair
 
I would definitely run a PCV system on a street car just so you wouldn't have to smell the oil fumes.

Nope sounds pretty cool. A lot of your specs and parts are not to far off what I am doing to my 360 right now.
 
Hope fully she will fire off pretty soon Craig AKA Hawaiiduster is coming up for the fire off so should be a good time, i get this new wiring harness installed and she will be ready to go :D Drop the seats back in and the new autometer gauges and cruise for a day or to the off for final paint and body and then the interior and she will be done.
 
Chad, I had those valve cover's and finding a grommet is tough. The aluminum is pretty thick and I never did find a grommet that would work so I made my own. I have a few twist on breather's I will never use again. If you want one I will ship it to you with the grommet I used. You will also need to make a baffle when you do the pcv. I used an old carb butterfly but and peice of sheet metal will work. I battled with this for 2 year's until I got it so the breather's wouldn't get saturated and drip oil everywhere. If you still haven't got the job done let me know and I'll save you a bunch of hassle.

Which grommet are you talking about? For the PVC or the breather? I have used the the factory pvc gromments with no problem. I dunno about the breather grommets I ussually use a K&N push-in and and push it into the capped hole.

Zombie you can use LA valve covers on a magnum actually but you have to leave out some bolts and some say that they dont seal well. :wink:
 
well i have a PCV grommet so I will take it down to the shop and pop a hole in it and go with that and then Order thaqt MOPAR Screw on bottom breather cap to fill the other hole. Hopefully this will take care of all of my problems.
 
the rough estimate is somewhere between 390 and 400 hard to say. I would be open to guesstimations from any of these rocket scientist.
 
So what is with all this catching up to me stuff you've been saying. Damn, were not just in the same ball park, were occupying the same base. :lol: :lol: :lol:
