Thanks for that! Looks nice!

I'm running full 5" exhaust from the turbine, to the tailpipe so I'm HOPING that won't be a choke point for me in the future Muffler is 5" straight through also.

Yeah, for now anyways I'm just going to do a catch can setup similar to 3 window. Maybe something more exotic later on but not likely.






I got about 10 feet of -10AN in the mail. Gonna try to mount it on the driver fender up by core support. I'm running out of room to put things in the engine bay!!!

Well said.

Interesting.....

I've inspected and purchased over 5000 engines from foreign countries. The ones with altered PCV systems or removed PCV systems are always disgusting, gunked up, pieces of ****. Even with just 44k miles I won't touch it.

You know how I can tell if an engine is worth a **** or not just by looking at it for an instant? I look how the PCV system is routed, and what kind of air filter is on it.



It isn't just a measure of engine health, it is a measure of owner's ability to deal with engine configurations, a measure of knowledge with mechanics.


Its like looking at a person naked and being able to tell if they eat right and lift weight or just let their own bodies decide how things should be and accept whatever happens.

Thats normal and has NOTHING to do with boost or crankcase pressure.

Nothing wrong with venting to the atmosphere. If you want to do a catch can, that won't hurt either. I've seen some of the recommendations in regards to where to get one here in this thread, but if you are on a budget...or simply value your money, there are cheaper alternatives that do the exact same thing.

This is the catch can I bought to use. Closed system. Regarding tuning although I have not experienced this iirc its possible a vented system coul mess up MAP values. I did run a vented breather on my first LS1 for a few years and its still running over ten years later so there is no sense in longevity concerns but it was MAF tuned so maybe thats why there are no issues. Anyways heres the can

Engines came 44 at a time in high cube containers from Japan since 2001 to 2008 and I was there when they are installed as a fair portion of them went into cars here in America, sometimes as swaps and sometimes as a way to get the original right hand drive vehicles back to operating condition (they are taken apart before leaving Japan to fool customs because complete cars are not allowed here from Japan) so it was essential to inspect each and then wire and tune them (its why I got so good/fast at doing engine swaps without ever having seen the engine before) I did this as a volunteer experience


I have everything to prove this existed: bills of lading, skyline motorex documents, proof of insurance and registration for RHD vehicles in Florida, a document from the dept. homeland security showing seizure of right hand drive vehicle, thousands of pictures of the swaps and cars with notorized bill of sale from their new owners.


I don't need to come on the internet and tell lies. there is enough of that already. So lets look at what we know for 100% Fact even if you don't believe any of the above:

Truth: Every automotive manufacturer in the world includes some form of PCV on their engine since like 1960's (maybe even before, I don't know) and that has never changed. Think of all the things that HAVE changed... basically every single part in every engine from then till now has changed. Every gasket, nut, part, pan, manifold, clearance, oil, we even got EFI and 7speed transmissions now. Everything has been redesigned and upgraded for the demands and efficiency of the future. Everything except....
the necessity of PCV systems
It was created and deemed essential before most of us were born and that never changed even with all the knowledge and science we have today.

For you to come along now without any engineering background (I must assume this because otherwise you would know better...) and modify or remove the PCV system without fully understanding what it does is classic, human error.


edit: just be clear I was a volunteer for these activities at various locations

I had crank case vent problems on a turbo LT1 i built years ago. I had over pressure causing a mess of oil leaks. I ended up running both valve covers to a sealed catch can with 2 ports. The valve cover lines merged and went to one port. The other port we to the down pipe to use as a vacuum source. It solved all my oil leak issues. The morroso kit i bought came with one way valves to prevent back pressure.

I just did the same setup on my LQ4 build.

Sometimes my memory is bad, but it seems I remember you saying that you are "just a poor College kid" roughly a month or two ago. But you've been dealing with engines for 10+ years......

Dude you are forgetting one very important detail that debunks your ENTIRE argument. Auto manufacturers are regulated. Vehicles and their emissions systems are regulated. You are arguing that closed PCVs are best? Nope, they are mandated, no more, no less. You are a smart one sided thinker which makes your answers/arguments pretty silly.

If this was true race cars would not use vacuum pumps and dry sumps would be useless.

[QUOTE=cam;19731864]Easy killer

I apologize for caring so much about spreading useful engine health knowledge, for if I continued to allow the propagated misconception that PCV was only a government mandated, restriction EPA sentence, and can be done away with easily, then I would be doing a disservice to my fellow human brothers and sisters.

For by this logic we shall all remove our PCV equipment in states with no emissions laws, such as Florida. Everybody in Florida should immediately buy a brand new car and remove any such PCV devices.

However, if we all do that, the engine at 45k would look more like 150k especially if any oil change interval were neglected. This is not what we want under the hood.

nice catch. As I said I was the volunteer in this. The owner was aware of the necessary PCV on the engine- because I warned him about it several times. However, his response was only "It looks cool". If you just want a cool looking catch can on the engine thats fine- but then the engine is disposable trash shortly after. This was not a problem for the owner since he was building 3 cars and selling 3 cars per month (bye bye pretty engine with no PCV).


If you are the type to put 3k on an engine then build another one etc... then obviously you won't care about the long-term effects of pcv neglect.


Even if you don't care about the engine health long term, there are still horsepower benefits to vacuum pump driven PCV, and there are still oil control benefits to having intake manifold driven PCV (the engine is less likely to leak). And there are ring seal benefits for both. The list goes on with benefits, besides just cleaning action there are many reasons to keep it working. Not a single drawback except if the engine health is already poor, ring seal is already poor, or baffle quality is poor, then you have to control the oil flow coming out of the crankcase. Thus the invention of the catch can, for engines with poor oil control. Since oil control is the most important aspect of racing (can't race with zero oil pressure, can't race with oil spewing everywhere), you immediately assume that this is not a racing engine. A racing engine only can become a competition racing engine once the oil is under control completely. I.e. approaching it is fully monitored and contained so that even in the event of a leak there are ways to conceal the leak during a race and alert the driver/crew for immediate remedy.

They are venting their engines to atmosphere which means that are not letting those vapors back into their turbos or intake manifolds.

I would personally rather wash my intake air duct out once every 15-50k miles and use the compressor cover to draw on the crankcase during boost, improving ring seal and reducing the chances of oil leaks during boost. It does not have to be a significant oil flow to this location, when the engine has proper oil control (so that it doesn't leak oil there). Also, it is fairly simple to clean a compressor (I've done it with a hose and degreaser, with the engine running, I even have a video if you want) of residual oil. You may also choose to vent to the atmosphere during boost instead, losing the benefits of a reduced crankcase pressure but also preventing any blowby gasses from re-entering the engine through the compressor. It is a double edged sword, since you might think you are protecting the engine from blow-by while in fact you are increasing the pressure on all of the oil seals, reducing ring seal (slightly more blow-by is likely) and creating slightly dirtier oil. Those factory turbo engines all had some form of oil control features (often factory convoluted ducts) which accounted for the minimal crankcase flow, and even over the course of 50k miles without being cleaned still looked acceptable on engines where the pcv systems had not been modified. As I have stated I have inspected thousands of these. The all original models with full pcv systems could often be close to spotless on the inside.


Keep in mind that every factory turbo engine in the world uses a tube to feed the crankcase which appears before the compressor of the turbo. A 'restrictor' is often placed in this tube on factory Japanese engines. It isn't to prevent the oil from getting out of the engine- it is there to induce a stronger vacuum signal during out-of boost situations, presumably to improve ring seal but also certainly improving crankcase gas composition.

This post might seem confusing so I will say in other words: there are two "directions" for blowby gasses on turbo engines possible. One is during vacuum situation, one is for boost. The boost situation presents is own set of problems and solutions for pcv systems, and yes, venting to the atmosphere is acceptable over sending it back into the turbo (if the engine has poor oil control this is your only option). However: THIS has NOTHING to do with the other direction of PCV flow, the vacuum side of things, which is all I really care about right now. You can vent the boost gasses wherever you want and still have a fully functioning pcv system under vacuum. I believe This is how the might mouse catch can is intended to be run and the only reason I endorse such devices.
