Nice Video as always

The bottom connection has a one way valve in it, so if you connect the inlet hose there, it renders the device useless. And could cause excessive pressure in the crankcase. It's like the old saying, "if all else fails, read the instructions".

Thanks for the detailed explanation!, I was also convinced the installation manual was wrong. Have you seen the new Provent2-200, that one they do have the in-out the other way round..

How do you know if the stainless steel middle insert is making the oil catch better as water vapors may rust it? Thanks

@moremolecules

Well, it is stainless steel, it cannot rust. On the other part of the question, I am not entirely confident that adds too much efficiency to the oil catch can, but still better than nothing. It does not restrict too much, but still adds a little bit of efficiency.

Appreciate your talk of the Mann-Hummel Provent, as it's the BEST performing unit based of actual testing (SAE paper). Have you done a video of with and without your added steel wool addition (like 3-5k miles with and without) to see if it really benefited?

I was thinking of doing that, but it is a false test. Most people will do amount of liquid collected and that depends on a huge number of factors. Say, the weather is a bit rainy, then the catch can will most likely collect a lot more water. One needs to separate the water and oil and compare only the oil amount, but that is difficult to do. In order for such a test to be valid it needs to be under the same conditions. So, I have not done it as I know it is not valid and I could not present the video knowing it is not right.

I have modified my Provent to be a completely sealed unit. Both the side valve and top valve have be sealed. It acts more like a conventional sealed catch can. My hose from the valve cover goes to the bottom inlet and the top is the exit to the turbo. I have attached a clear plastic bottle to the bottom of the Provent and it collects a tremendous amount of oil/water before they ever get to the actual filter. The top line going back to the turbo is always oil-free. Your comments, please.

@moremolecules

To swap them, so the inlet is at the bottom and outlet and the top, I have commented in the video on this. Not too sure about the completely sealed part that you have described, could not quite understand how it is a completely sealed unit. The bottom has a few steps or the flow has a few barriers. Water/oil will gather there and will restrict the flow a bit and a bit more crankcase pressure as a result.

Question, sir, I have a mustang 4.0 v6 with a supercharger. Currently the setup doesn't have a pcv hose connected from the valve cover to the intake. The intake has been fabricated to house the super charger and thus no port. So the builder left it off the engine. The pcv valve is there, but again, Nothing connected up. The lcv is on the passenger side bank. The drivers side bank has a ccv and again nothing connected- no hose. What are your thoughts as to what I should do here for ventilation? I was thinking breather valve on the oil cap and catch can for the pcv and ccv. Your thoughts? Please and Thank you.

@moremolecules

Жыл бұрын

Yeah, diffiult to recommend anything. I would do it as turbochargers do it, connect the PCV to the intake manifold, kind of pre-supercharger. You will get the benefit of negative pressure in the engine from the turbocharger, i.e. pulling a bit of oil out of the crankcase. You can extend those with hoses.

@alfenner3309

Жыл бұрын

molecules ok, I'm going to do a metered test on the crankcase pressure. I believe I can get away with a oil cap breather and remove the pcv and add a ccv and then run "in" hoses to both in ports and run an "out" hose down to the frame. I know that is an emission no no, but I live in an area that isn't an issue. At least until i can figure this out. The issue with putting the pcv hose on the intake, is because there isn't a port for it with the fabrication of the intake to house the supercharger. At least I can't locate it. Usually these are very noticeable either on the front of the intake or in the rear of it. I'm bot seeing anything. Also need to mention the supercharger is off of an 04 ford lightning. But I'm nor seeing how it is attached on that motor. This is tough because it is a strange install. I'll add the car runs fantastic as it sits, but I'm really worried about the pressure Thanks

@@alfenner3309 That's a tough one. Measure the crankcase pressure and see if it is excessive. If it is not, you do not need to evacuate it. Rather difficult to know what is normal and what is not with crankcase pressure. If you have access to another without the supercharger you can compare. I suspect that if you setup your oil cap breather to something sensible you should be able to achieve crankcase pressure relief. On mine, but it is engine specific, it is ~30mbar. The Mann-Hummel pressure relief valve is 50mbar.

Do not know much about the 150, but also really difficult to say about the 200. I have not made an efficiency comparison between the fake and the geniuine one, so difficult to comment how much worse it is. It certainly filters oil, so it works, but how well is difficult to say. It could be that it is say 50% worse than the original, but it could also be almost the same. Probably safer to say that it is better than no oil catch can.

As MM says, you need to be a bit more specific with your noise problem. Common harmless noises are low rumbling from a loose airbox at the back of the engine, MM has a video on this. or the 2 big in/out airpipes banging against each other - just tape or tie them together. If it's more of a metalic sound near the turbo it's probably the upper heatshield breaking off its mountings. If you have a ticking sound it could be a loose injector (especially if it's when idling after the engine is warm). Take the engine cover off and look for little puffs of smoke in time to the tick. There are many videos on KZread on how to change the injector seals. You'll need a 7mm hex/Allen key and tightening them up a bit can help limit the noise but the seals will need replacing as soon as possible.

well the explanation is little Physics,The demister coil acts as condenser and retention extender so more vapor will condense. Flow of air is parallel to the flow of condensed gas or oil so entering from top tube both gas vapor and condensed gas flows parallel towards the bottom.If the flow is starting from lower nozzle,when the demister coil is oil laden or saturated,the oil will flow by gravity towards the bottom of can.If the entry of gas starts from bottom then gas flow will meet the flow of condensed vapor or oil so re-heating of condensed oil by in-coming vapor takes place.

That Mishimoto and every other overpriced metal can like it are TERRIBLE with too many design flaws. The provent is basic proven technology, and the best oil/air separator I've ever seen.
