20 f350 drw. I was going to swap out the oil seperator for the newer style. Since its still under extended warranty I was going OEM. Went to local dealer they are on backorder. He has 23 on order and said that 10k are on backorder nationwide. Has anyone used the aftermarket ones on Amazon?

 

I would either wait on a 23 model, or I would go with the SPE Recirculating CCV box.

 

This is for the 23+ ccv. 22 and down you can find cause nobody wants them.

 

As for OE boxes, I wouldn't put anything but the most current, 23 model on. Otherwise, like I mentioned above, the SPE recirculating box would be a really good option, and while it is about 3x more than the OE box, since it has a cleanable filter, you will never have to change it again. So, in time, you will easily make up for that extra bit of money!

 

I just put one that was from Amazon, lokked good and seems ok. Probably have 300 miles on it.

 

Or just vent to atmosphere with a CCV box delete kit like this... https://www.spemotorsport.com/collec...cv-reroute-kit
and this

I've had good success with mine

 

The best way ever. I don't care how many companies can try and reinvent the wheel with their products...........bottom line is that they all still send the gases (oil vapor) back into the engine...no thanks. I went with this kit three years ago and still enjoying the freedom and never worrying of a clog.

Interesting kit Jim, there are no instructions that I could find in the listing, does that just vent to atmosphere under the truck?

 

I have the SPE CCV Reroute and the External Catch Can packed up in a storage unit in FL. Right after I got it we figured out we were coming to CA for about a year, so I didn't want to have to deal with that while we are here. And to be honest, I am still up in the air about installing the reroute... Plenty of folks with reroutes/vent to atmosphere claim that they see smoke and they can smell it when stopped (such as at a red light). Some claim that oil selection may have some to do with the smell and the visualization... I have seen Rotella (a popular PSD oil) referred to as Rosmella in reference to this. Of course I use Rotella, however, I am switching over to Amsoil on my next oil change though (regular HD, not signature series...) Also, (on a touchy side) there is a bit of talk about the vacuum from the intake side playing a role in helping to pull the gasses from the crank case... The reroute will obviously eliminate any vacuum assistance in removing crank case gases. Whether this is good or bad... I have also read about how important it is when running the reroute line to avoid dips, and to keep the line short so that the airflow is not restricted, which could actually cause an increase in crank case pressures. I don't want it terminating right in front of the cab so those smells don't come inside, but the farther it goes back, the more likelihood of pooling and increased pressures... Also, I am not interested in running it all the way back to a venturi in the exhaust, or the added complexities of doing so. Then, the drips... This is part of why I opted to grab their External Catch Can. The drips will drip into the catch can. But this also turns into another thing to maintenance (albeit, an easy one, that doesn't cost any extra $$!) Speaking of which, costs... I paid about $600 for the SPE reroute kit and the external catch can, so it's definitely not cheap! Sure, there are other options out there that are less expensive though.

Not saying all of this to say that a CCV reroute isn't a good idea, but to point out that there are some considerations to think about when deciding if you want to vent to atmosphere, and then how to do it. Truth be told, I will likely go ahead and install mine once I get out of CA!

 

Its a very easy install, no instructions needed imo. I have the hose (10'x3/4") going to a home made catch can that is mounted on the frame before the rear axle, gases escape freely and the liquid gunk settles into the can that gets drained at every oil change (5k mi).

 

My truck is still under warranty. I assume a ccv delete will not fly if I need work under warranty.

 

Depends on what the warranty work is on and if it is related to the mod. They are supposed to prove that the mod caused the damage. But, at some point we have to decide how far are we willing to go to prevent issues so we don't have to worry about dealing with them when they occur... or better yet, dealing with the dealerships. Not all, but many will do their best to get out of anything. It took me a couple of months to have some issues with the paint on my new truck dealt with... on a brand new truck. They tried so hard to get out of it....

 

The true purpose of a ccv reroute is to stop the crankcase gases being inducted into the engine via turbo and it will also mix with the dry soot from the egr system, mixed together it makes for a black tary oily crud, best seen behind the throttle plate. All the newer ccv systems including the aftermarket do nothing to prevent the mixing.....so a true reroute to atmosphere is the fix and its been done on engines for decades.

 

All valid points. The SPE kit I use has an internal cheese grader looking part that condenses most of the oil vapor before it leaves the valve cover. The gases coming out the hose have never dripped any oil as a result. The hose goes over top of the brake booster and exits behind the left front mudflap. In cold weather you will see some vapor coming out. The only time I smell anything is if I'm in a drive through stopped with high idle engaged with my window down. Other times it hasn't been an issue.

 

I have read several other posts like yours too, and it's what makes me think I am going to just go ahead and install mine once I get out of CA. I do like that SPE has designed theirs to run over the brake booster. I figure that does indeed help with drips as it gives the liquids farther to go before gravity helps them drip out of the tube. A lot of others I have seen is simply a right angle adapter coming straight out of the crank case and then immediately drops down. As for the "catch can" I opted to go with the external catch can over the internal catch can. I have read that these are 2 pieces as opposed to 1 single piece, and I have seen concern about it coming apart and then the grater part could fall down into the crank case. OTOH, I have read of others complaining about drips even with the grater. Some have alleviated the visualization of drips by running the end of the hose into the frame. This actually seems like a good idea as any drips would just get trapped inside the frame, and it would also somewhat help with any smoke, or smell. Somewhat of an external catch can... Had I went with the internal catch can, this is likely how I would have routed the hose. But, I figure the external catch can will 100% catch any possible drips, and may possibly help with any smoke or vapors.
