KnifeySpoony Posted October 5, 2021 Share Posted October 5, 2021 I still don't know what they expect on cars with without an intake manifold/plenum (ie direct to head throttle bodies). My dry sumped duratec on roller barrels has no way to implement a pcv that I am aware of. Hopefully just routing the oil breather from the tank to the airbox will be adequate.

TomSalter Posted October 5, 2021 Author Share Posted October 5, 2021 https://caterhamparts.co.uk/other/5962-hose-air-intake-seven-275-model.html Looks like this will do the business. My 310S has just a straight pipe from cleaner element to throttle body, so this gives a nice connection to the PCV. Should work great! -Tom Link to comment Share on other sites More sharing options...
awatkins Posted October 5, 2021 Share Posted October 5, 2021 (edited) Tom. — No, it will not work great. It will fail. The PCV valve is to be be connected to the intake manifold NOT to the airfilter in any way. If you use that Caterham tube connect it to crankcase. I want you to pass this test because if you do it will prove that there is no problem with BAR or CARB, and I can confidently order my kit.

TomSalter Posted October 5, 2021 Author Share Posted October 5, 2021 Oh, I missed your diagram! Makes total sense. Thanks! -Tom Link to comment Share on other sites More sharing options...
awatkins Posted October 5, 2021 Share Posted October 5, 2021 Great! By the way, one more detail that might ensure you sail through: some people have said their referee wanted to see “PCV” hose used for that connection. Sounds strange but they do sell it at parts stores and it would be a form of insurance: https://www.oreillyauto.com/detail/c/prestone/belts-hoses/hoses/bulk-hose/anti-smog-pcv-hose/81d6b29f64f9/prestone-crankcase-vent-hose/prs1/cv1132?pos=2 Link to comment Share on other sites More sharing options...
Heloman Posted October 12, 2021 Share Posted October 12, 2021 So here's the latest in my saga. A month ago, after sixteen months, I was approved for an appointment with the smog referee. I made the appointment and the soonest I could get in was today. I thought I could get by for a PCV requirement by running a hose with a PCV valve from the breather in the block to the backside of one of the Weber air cleaners. Nope! Didn't happen. It has to be a system that pulls fumes into the intake manifold and vents it back into the engine. So now, decision time. Do I sell it out of California or figure a way to fashion a PCV system on a car that never had one without spending a fortune? 1700 Super Sprint, crossflow.

awatkins Posted October 13, 2021 Share Posted October 13, 2021 It’s not hard and need not be expensive. Find someone who understands this stuff. Link to comment Share on other sites More sharing options...
papak Posted October 13, 2021 Share Posted October 13, 2021 You just need to run a hose from either the crankcase vent on the side of the block or the valve cover to a barbed fitting installed somewhere in the air filter housing, SB100 does not require smog compliance. That is one of the major advantages of the rules. Link to comment Share on other sites More sharing options...
awatkins Posted October 13, 2021 Share Posted October 13, 2021 papak -- SB100 absolutely does require any smog equipment that applies to the engine as of the year of the engine or year of the body, whichever the owner chose. California cars all had PCVs since 1964. Even so, what anyone thinks SB100 specifies is irrelevant. What the Referee wants is the only thing that matters. Many referees, if not all, require an actual PCV system. What you are describing is what Heloman did, and it flunked. What he needs to do is what is shown in this picture: Link to comment Share on other sites More sharing options...

Heloman Posted October 13, 2021 Share Posted October 13, 2021 You are certainly correct, AWATKINS. And thank you for the simplified diagram. Exactly what my referee said. He said I could take a hose from the breather in the block run it through a PCV valve into the intake manifold. He also said I would then have to run a hose from the oil filler cap or valve cover to the air cleaner using a non vented cap. My big problem is the intake manifolds have no provisions to take vacuum for a PVC system. Will be contacting various Weber experts today. As mentioned what I had was what papak mentioned.

TomSalter Posted December 14, 2021 Author Share Posted December 14, 2021 I think there's a chance you'll pass. He was very brief, I told him I had a closed PCV system, he didn't look very closely, and then went off and did the paperwork. And Sean - done! :-) Link to comment Share on other sites More sharing options...

Heloman Posted December 14, 2021 Share Posted December 14, 2021 Hi All, Like Tom Salter I had my referee appointment today and it was quick and smooth. I got there early but my appointment was for 8:25 and I was done by 8:40. Just a minimal inspection and I was on my way with paperwork and a sticker. Then to DMV where I turned in all my paperwork and left with plates and registration. That took about 15 minutes. It's been a year and a half journey because of an out of state purchase, Covid and dealing with the BAR. But it's all over now. Thanks to all of you who offered some good informnation and encouragement. Much appreciated. Cheers! Dann Link to comment Share on other sites More sharing options...
