broken pcv crossover hose Ok so i was just changing my oil pressure switch and i just barely touched the pcv crossover plastic hose and it snapped. I'm having some trouble finding a new one and i need to have my engine back together asap, anybody know where i can find a new one? I don't necessarily need the whole thing i just broke where it comes out of the driverside bank...i have a picture attached. SOMEONE PLEASE HELP!
Goto advance and get
1. PCV groument p/n# Dorman 42056
2. a packet of 3/8 clamps
3. a good amount of 3/8 hose
4. new pcv vavle
5. about 4 inchs of 3/4 hose (they just gave it to me)
Then goto Lowes and get
1. 1 brass 90 degree fitting
2. 1 brass tee fitting
3. 1 3/8 to 1/2inch brass reducer (looks exactly like a garden hose fitting)
Sounds like alot but I think you'll be out for like 12 bucks
Slip the groument into driver side valve cover. Cut one piece of hose to the with from one valve cover to the other. Put tee fitting into one end and the 90 degree in the other.
Add the 90 down into the groument on the driver side valve cover. Cut a short piece of hose and run it from the rear passenger nipple to the tee fitting.
Now step away from the car for a few minutes.
Grab your large section of hose. Take the new updated PCV (fixed orifice) and slip it into one end of the large hose, then place the reducer (garden hose looking fitting) into the other. Place one hose clamp on each end of the now double ended fitting and tighten then down tight.
Now go back to the car, cut a short piece of hose and attach it to the pcv fitting you just made (brass side towards the rear of the car) and run it to the 3rd nipple on the tee fitting. Add a piece of hose on the silver nipple and run it to the intake.
I did this recently on my car I can get you pictures if it will help.
PS. my sizes might be off I'm pulling this all out the top of my head, just take the pcv valve and the groument for the valve cover with you and you'll work it all out.

Yes 3/8 fittings and 5/16 hose, you can squeeze them into it nice and tight.
I don't want to tell you wrong though, like I said I'm pulling this off the top of my head. Let me check and I will get back to you.
EDIT: I checked and I am using 3/8 hose so I want to say that if I used 3/8 hose I must have used 5/16 fittings.

Verdad Gallardo Ok in the first picture you can see the the pcv grommet Dorman P/N 42056
and the 90 degree fitting. The ID on the grommet is .418 so I believe a 5/16 fitting is what I bought. Just take the grommet with you and test it.
Second picture shows the PCV valve and the reducer mated together and the tee fitting. Connects the driver side and the rear nipple together and then leads to the front of the car.
The third picture shows the line coming off the tee. Mine goes to a catch can before entering the intake manifold. Yours will just skip straight to the intake.
You can also see the clean side line running off the throttle body to the front passenger side nipple for reference.
The hose is 3/8 BTW so make sure your fittings will fit nice and snug so they don't become disconnected. Again, I believe I used 5/16 fittings, but I can't remember guys sorry.

The reducer allows you to have to of the same size nipples for the hose on both sides. The PVC valve it's self is somewhere around a half inch in diameter. You stick the fat end of the PVC valve into the female part of the fitting. Or better I should say slip each into the large hose you bought, push them until they butt together and then seal everything up tight with the two clamps then install it in line between the tee and intake manifold.
Ps if me calling it a reducer is confusing I apologize, it's actually a 1/8 NPT female to slip fitting.

Time for an LS6 PCV conversion, that's what I did when mine broke during a head swamp. If you want a new crank hose, that would be $100, so I just went for the LS6 Valley cover.
LOL, he said quick fix & someone suggested the LS6 valley cover swap which is far from quick. They also forgot to mention he would need to notch the block under the cover to do that swap too.
What My6speedZ suggested is the cheapest/fastest route to get back on the road. Adding a catch can would be a good investment eventually. I also have a new PCV valve, 3/8" hose & assorted barbs/tee to build my own. Just gotta stop being lazy & get it installed with my catch can.

And even with the LS6 valley cover swap you still get oil in the intake. So why go through the extra time/work when you can do this quicker/easier/cheaper? Only way to keep oil out though is breathers and no PCV system or a good catch can properly routed.
Beat me to it, there is always a ls6 valley cover nutswinger in every PVC thread. Just add a catch can that has a baffle and make sure your lines are right and your good to go. All without pulling the intake and grinding.
