^^^^ What he said. I had an older Norris catch can, and I will say this MMS one is nicer.

 

i'm not sure which MM one to get either. I have the 2 heater hoses coming from both valve covers so I want an MM can with 2 inlets, and then one going to the either the tbody fitting or the one right behind that on the intake (not sure which one of those it should go to actually).

currently, no PVC installed. its got 92mm intake. don't see any tubes from center valley.

 

You could remove the sight glass and install another fitting as a second inlet

 

So for a basic street car what is the one to get?

 

Mine is a basic heads/cam street car and I run the PCV can.

 

Like white lightning said, run another barbed fitting in place of the sight glass. Run a hose from both valve covers to the can. Then the clean port to the intake right behind the TB. And if you have a ls2 valley cover I would run it to the air lid somehow.

You can see what I'm talking about here:

 

under say 700 horse the single inlet is fine, and my suggestion to find one in stock would be ws6store (sponsor here)

 

Just got mine today

 

thanks dude

Do you think that instead of putting the 2nd input where the site glass goes, that it would be OK to just "Tee" or "Y" both hoses before they go into the MM can? Then like your routing out the PCV and into intake.

 

Yup unless you're making a ton of power. Just T them together then run to the intake port right behind the TB and then the line from the valley cover to the lid. You can see how I ran mine here. I did run a hose from each valve cover tho. But the T would be fine I would think. I just used a 3/8" barbed fitting. I drilled a hole just a hair smaller than the threads in the lid and tightened it into the lid by hand. Nice and tight

 

got the new pcv gen 4 can in today. ordered the ls head mounting bracket. Question is what size bolts are you using to mount the bracket to the head. Size, length, thread pitch?

 

Mine came with bolts. But it's whatever size the alternator/power steering bracket is.

 

Why isn't this on my car?

Time to fix that.

 

Was just wondering on the black pvc can ... I bought mine off a guy and he had none of the info ... pcv is on the highest port and going Into the center chamber between one way breather and lower element ... my qestion is on my turbo silverado I don't have a port or airfilter on the inlet side ... so will it be okay and safe to hook to stock port on top of intake and run both valve covers two the other two ports ? ... if not them how should I hook up to keep the pvc system as stock as possible .. oh and stock gen3 Valley plate (no port)

 

I talked to David at MMS and he said this......

A PCV system is the constant turnover of regulated 'dirty' air being drawn out to the intake manifold which causes 'clean' air to be drawn in another port on the engine to replace it. You cannot have a PCV setup without this fresh air 'in' port. This means that the 'dirty' side fitting needs to be large enough to support your power level. MMS has options for this like the oil fill adapters. The dotted lines are options on the diagram:

 

One bit you might notice if you don't use a PCV style is that your engine can collect a lot more moisture in the crank case, the vacume/suction helps evacuate water vapor as the engine warms up. If your running methanol injection its even worse. This is no big deal on a race engine that's getting fresh oil every weekend but for a street driver PCV/CCV is mandatory for me..

Let than .02 bucks worth,,,


YMMV just a thought..

 

I replaced my RX can with the MM since i was getting blow-by with it. Very dissapointing considering how much i paid for it.

Not a fan of the MM bracket since it will scratch the can once tightened so i put some gorilla tape on the inside of it. Paint was so so, spotting all over the finish looks like poor prep. Custom colors in powder coat would be a nice option i would pay for. Other than that it looks like a solid setup, no testing yet as my car is in storage till may.

 

If using the sight glass as the second port to the passenger side valve cover does it matter if it goes to the front or back connection?

 

Anybody have trouble fitting the hoses over the piping? Especially to the throttle body?
