I put a stainless double barbed 90° on mine and routed it to passenger side. I got the spe kit with the intern catch can. I got two 4" to 3.5" adapters and tig'd them together on the 3.5" dia and added an evac system for a true venturi with the venturi system you mention. It draws 6-8" hg at 2-2100 rpm where it spends most of its time. It was deff a more involved job and routing spe's reroute hose is floppy I only used a small section of it. I got a b-nut and sleeve, flared 5/8 x .035 wt 5052-O tubing and it runs the same path as the exhaust up to and behind a harness, trans and oil dipstick tubes where it terminates about 8" from the spe spout. I ended up using only about a ft of the spe hose. Thanks for this video, good idea with the catch can but I didnt have the disposal income enough to get that expensive catch can. May add that at a later date if needed but as for now i see no oil deposits out of the straight piped exhaust. Planning to install a big muffler and fab up a similar looking stock twin tip - try to run under the radar so to speak.
Lol 😂 I can’t believe that you actually think that the Venturi principle that you are attempting to use works like you are stating. The amount of flow from your exhaust that you are depending on to assist the evacuation of the CCV system will not over come the distance (length of hose = friction loss), or the all the bends made by the hose starting at the valve cover itself (twist and bends = friction loss). To prove my point disconnect the hose at the valve cover and have someone raise the RPM to about 2500, place your hand over the hose and you will feel NO suction. To prove it even more light that cigarette and blow the smoke over the hose and you will see NO smoke entering it. To make matters even worse you actually ran it thru a catch can (more restriction and more friction loss) The CCV system does not require th engine to help suck out the gasses, the ONLY reason it is routed into the intake is to meet EPA guidelines. What you did was a complete waste of time and money. It is far better to just run it without the SPE internal catch can with only about 3 feet of hose to the atmosphere. Dude you are a hot mess, did you even think about what you were doing or just buy something off the internet and then tried to make it better ? Any knowledgeable diesel mechanic will laugh his butt off when he sees that useless conglomeration of parts ? 😂😂😂
Mechanic or not pal, you can’t overcome basic physics (in this case regarding hydraulics) the amount of “suction” that you think you are getting running the length of the line, thru fittings,than a catch can and finally into your exhaust system just isn’t there. But keep puffin on cancer sticks, sucking back cheap beer and talking about your high school football days with your buddies under a tree while you pull a transmission. 😂😂😂. I actually went to school and learned physics and hydraulic engineering and am now fully and comfortably retired at 54. But hey what do I know 😂😂😂
He is absolutely correct. CCV systems on diesels and gas engines exist solely to reduce emissions and unwanted smells. There is zero need to vent the crankcase into the intake unless you like running oily fumes through your turbo and intake plumbing. This is true regardless of how hard you work the engine.
Never had an issue on my 12. Don't think id do that in Michigan. All i see is a place for condensation to build up from hot and cold temps and plug that can. Also probably corrode together, depending on the fittings.
SPE Ccv reroute for over 100k miles hauling heavy no issues. Don't tell me that the factory system was drawing it out whenever there is excessive crankcase pressure. Had seeping upper oil pan put in new oem ccv filter still seeping. Did reroute and all seeping stopped. No need for that setup, unless you are bothered by smell or haze.
I did everything you said, but I decided to run it back into the turbo because I got tired of dealing with the smell with no oil going into the turbo like it used to have
@@JakeScott-ke3sh I put all the smog back on the truck and sold the truck and went back to gas. I’m done dealing with the smog on these diesels. I have a VW Passat diesel and no problem with it but I went with a 6. 2 and I’m happy.
Thanks for the video and your insight...much appreciated. Question - do you remove the tube from the Venturi fitting if you perform a static Regen? Seems that the heat would potentially melt the tube as temps on the downside of pipes...can reach upwards of 450 degrees. Thank you in advance!
@@Blacksmokematters1 - Thank you much! I have the Venturi fitting on order and will install post DPF and farther back. Tube will also be attached to frame and then directly down to Venturi fitting. Will also go without Catch Can initially... On another note...some harsh commentary at times on this post...
Thanks for your vid. I am trying the same system but am not getting any vacuum from venturi. Is your DPF still installed or do you have a delted with straight pipe? Thanks for a reply.
So what if i run the hose back into the intake from the catch can filter under truck, it should work thw same way for vaccum right? Id appreciate the feed back. Thanks
I'm looking at a 2012 F250 with just a tad bit more blowby then normal, but the individual also prob hasn't changed the CCV filter in over 100K miles also so i'll prob pick up the rig for 6500-7k swap it out and eliminate the present blow by lol. But im trying to figure out when I do if i wanna just delete it with with a SPE kit or for the time being just swap the OEM CCV.
Very good video. Have you been able to check or measure with some throttle input or under load, that the exhaust is still creating suction? I would prefer to ask someone that is using this setup, vs reading forums that quickly turn....well...juvenile. Thank you for the feedback. It is much appreciated.
Yes I generally will pull the hose off every other oil change and meter the vacuum from the venturi fitting to make sure its not clogged and still creating vacuum I have not had to clean it yet.
Where can i get the products in this video? Exhaust kit, catch can etc. Also if someone had an '18 6.7, hypothetically if one were to do this, would they a tune be necessary to run correctly?
So I thought that if you had the first style ccv from the first gen 6.7 power stroke the one that don’t have the bolts on top to service a rod from power stroke talk or w.e it’s called said we didn’t need the kit if you had that one
@@Blacksmokematters1 I owned it for 6 years now just heater sensor on the dpf and just stay on top of my maintenance my fuel filter and oil changes and coolant I did have a new water pump installed to and ac compressor and I think that’s it she Ben the best truck ever I always every fill up no matter what use fuel additive every day diesel or diesel Klein I do live in California so emissions is intact full stock with 6.5” fts radius lift kit 35’s 20x12
why does nobody plumb it into the catch can then back to the intake where it originally hooked up? it would help with crank case evacuation and no smell.
@@Blacksmokematters1 How did you test the venturi for suction? I installed mine back of DPF and I can't get a vacuum for all my efforts. I'm about mid way on the pipe section just after the DPF. I am getting positive pressure blowing out of the venturi. Thanks for a reply.
@@paul91103 sounds like you may have installed the venturi backwards that will cause the symptoms you are experiencing. The venturi works best under load the more exhaust flowing is what creates the vacuum especially with stock exhaust.
