CA SB100 question: PCV and what else?

lippy · #1 (**permalink**) 11-11-2013, 03:32 PM

Since I'll probably get my car on the road in January, I've started to read and plan for the CA SB100 process. I think I've got a decent grip on the process, and the car will be registered to conform with 1965 smog requirements. I know I need a PCV valve. Is there any other smog equipment I'll need?

Yes, even though it wasn't required in the 60's you will need a completely closed pcv and breather system. If you have a breather on the opposite valve cover, it must vent into the air cleaner, not the open air. Many have failed by missing this simple requirement (myself included). Just buy a cheap breather with a hose attachment. Then you must attach the proper hose (one suitable for a pcv valve, not just a fuel hose) and run it into your air cleaner base. You can buy all the parts for about $15.00 at O'Reilly auto parts. You don't want to fail and have go back for a second appointment.

Ok, thanks. So I need a breather with a hose from the valve cover to the air cleaner. Sorry for my ignorance here, but do I also need a connection to the carb (if so, to where)?

Nope, just to the air cleaner. I had an old air cleaner laying around so I drilled a hole in the base and attached a fitting that attached to the breather hose.

lippy,
jhv48 speaks the truth.
PCV on one side of the vc to the carb, and a breather on the other vc piped to the bottom of the air cleaner.
They WILL fail you in a heartbeat and make you reschedule.

And I'm sure you know this already, but make sure you visit the CHP and get their paperwork signed first, before going to the BAR referee.

Here's a picture of a closed PCV system:

Again, sorry for my ignorance here. I'm reading two things on this thread. Do I need: (1) only a PCV valve and hose from one valve cover to the air cleaner, or (2) both a PCV/hose from one valve cover to the air cleaner, *plus* another hose from the other valve cover to the carb. Thanks again!

There is a special port at the base of the carb that you run a hose to one valve cover with a PCV valve( it will draw air in to the carb) The other valve cover will need a hose going to the air cleaner.

The the image above for the closed type system used to be called a type 4. One hose from the PCV to the carburetor base or spacer with a PCV fitting and the other hose from usually an oil filler cap to the air cleaner. This is what I have on my roadster and went through the visual without a problem. These oil filler caps can be bought through Mustang or Ford aftermarket parts dealers. But, everyone seems to have a different experience when taking their cars through the BAR referee station.

Just a note here, there was a retrofit program in the mid 1960’s in the more populated counties in California that required certain items be installed on cars dating back to 1955. One was the crankcase retrofit which routed blowby from the crankcase to the intake manifold and the other was the exhaust retrofit kit which basically was a kit for keeping you distributor from advancing when certain conditions were met.

I don't think you need to worry about the retroifit mentioned above. Just have the PVC set up as pictured. I had a brand new 1965 Galaxie and it only had the PVC on it and was never inspected for smog as they didn't start that up here until 1966. On my Cobra I put the PCV set up as shown for two reasons. One is it relieves pressure that would otherwise blow oil fumes and crud onto your valve covers and the other was it is easy to do. If you con't have a spacer under the carb with the place to hook a hose from the PCV valve which will be in the right hand valve cover, you should have a place in your intake manifold that you can take the plug that is probablu in it and put in a connection to hook the hose to.

post a pic of your motor......so all concerned can see what you have and then we can point out what to do

I will when I get it

I just started to think about this problem when Brent pointed out to me that my Holley Ultra HP carb doesn't have a PCV port. I'm planning on getting my SB100 cert in early January, and I'll probably have the car inspected in Jan or Feb so I have a lot of time to solve this problem.

The back of my carb has a 3/8" (I think) connection for the PCV hose that comes from the passenger side VC. The drivers side VC has a rubber grommet instead of a cap with a metal elbow connecting a 1/2" rubber hose to the bottom of my air cleaner through another metal elbow. HTH.

These guys are right. Just got mine done. On one side of valve cover you need a PCV valve to a vacuum port on the carb, whichever port your carb is set up for to run the PCV (or you can use any vacuum port if you want). The opposite valve cover needs a closed vent air breather with a rubber hose to the carb air intake. It must be "filtered" air according to my referee. I drilled the base of my air cleaner and attached a $10 fitting and it was done. I left mine on, looks good and used a chrome air breather. Once I did that there were no issues. Will try to post a picture.

The braided hose goes to a fitting I mounted under the air cleaner base, a brass fitting with 5/8" hose connection, $5 at home depot. the chrome air breather was $20 at O-Reiley. On the opposite valve cover is the standard PCV valve with a hose to the front of my carb vacuum port. For mine that is the PCV port. Yours may be different but you have one or need a carb spacer with a port. You will NOT get through without this set up. If you are lost take to a local mechanic that works on rods and they will know exactly what you need.

lippy,

To add to the above, be sure the hose is clearly labeled PCV, Emissions, SMOG or similar verbiage and install it so the wording can be easily read. This goes for the hose from the PCV valve to the carb base and the hose from the oil filler / breather cap to the base of the air cleaner.

Any as RodKnock said, CHP inspection before BAR. The Santa Clara DMV provides a checklist if you do not have one already. I went to the Dublin CHP for the VIN verification, bring all your receipts.

Also keep in mind, the BAR referee is the one that will install the all important sticker with the SB-100 number on it. Think about where you want it, it has to be on a surface that is not removable … I was thinking of putting it in the trunk, but each spot I picked the inspector said the panel could be removed. So we settled on a location on top of the driver's side foot box, tucked up and out of the way. Some owners like to have the sticker right out in the open, matter of personal preference.

Be prepared and you will do just fine

Tkb is right, - however Santa Clara DMV no longer has the good personnel working there., = be polite and know your stuff. -- if you need help , send me a PM and I can talk you through it.

I have so far successfully registered two cars through the entire SB100 process and was never able to locate any special "PCV" or "Smog" hose and just used good ole fuel line or yes, believe it or not for the breather side, heater hose!! I just made sure to wipe the hoses down with Goof Off to remove any existing labeling on the hoses and had absolutely no problems getting through the BAR Referee at Golden West College in Huntington Beach. All the referee wanted to see was that I had a closed loop system in place with the PCV valve in the valve cover connected to vacuum on the carb (used fuel line for that one) and a closed breather cap on the other valve cover with a heater hose connection to the base of my open air cleaner. Again, I have done this successfully with both my Superformance Cobra and a 1932 deuce highboy. Guess what happened to that heater hose connection to the breather cap about two seconds after I got home from the Referee? "Gone like a '59 Cadillac"!!

Glad I saw this. I think I have all the parts I need to get this done. I have the valve cover grommet, PCV valve, and an "EPA" hose to go to my carb. For the other side, I bought another grommet, a breather cap with a 5/8" fitting, and another fitting I'll install on a cheap air cleaner base. Problem is that I couldn't find the proper hose in 5/8" size anywhere (several local parts stores, Jegs, Summit). If anyone knows where to find this hose, it'd be great. Otherwise, I'm going to use the Goof Off/Heater hose approach.
