catch can research shows it's worthless

[PQ]

My take was always WGAS because the engine will be just fine without a can.

There are some smart guys on here engine wise who advocate for a CC so I put one on my car. I saw my intake after it dripped oil on me when I took it off to put the supercharger on here.

That being said, I think it's made a bigger deal than it really is. Even with Tracy and others giving their educated opinions I suspect a CC would most likely never matter in the end. Especially since most of us won't have the car long enough for it to matter.

But my opinion is just a gut feeling. A strong enough feeling to have me buying one anyway just in case.

Seafoam, seafoam, seafoam.

Bottom line for me, I'm no expert and there are guys on here who are. For the cost, I had no problem giving up my money. Hell, like the one guy said, if nothing else, it looks cool. hahahaha

right there is what most camaro/most car owners want, and why GM does not really address this problem like people think they should.

i personally see why people would put them in, and going by info here, its hard not to.

Where are some pictures showing the same type of engines running one with the same miles.
Carbon is also in gasoline and will coke up also to a degree, but how much less??

Just a simple observation because I have seen race motors torn down that just used breathers and no PCV and had buildup.

Here is where you get the idea. You posted in your first thread that a CC is totally worthless and clearly it's not. It's not 100% needed but neither is your aftermarket catback, CAI, headers, aftermarket rims, swaybars, springs, etc. All of these do make a difference though.

Yes, because the stuff gets ejected when the motor gets hot but you need to maintain flow in one direction to properly clear the crankcase

At 68,000 miles my LS1 was so caked that it was performing a lot slower than it was being new.. the detonation would throw the car into the low octane table while going down the track... it was like a parachute being deployed

BUt that was with a cam and a lot of rpms all the time... The clean air return was a bad setup...

Yes if you your not going to keep the car 50k or more chances are you wont care and wont notice but if your in it for the long haul.. its a good idea to keep the valves and intake tract clean

I think a catch can is important for someone who wants to keep this car till they die.

Most people who own/drive vehicles don't do that. So a catch can wouldn't be needed. If you change cars before your engine dies... you don't need a catch can.

I think the product is a good preventive measure for anyone who plans on having this vehicle for decades and want to have as few problems as possible during their ownership. You won't see the results unless you tear apart engines for a living. So for the average person it has no quantifiable worth. But for an enthusiast it has its worth.

Useless? No.

Unecessary for most vehicles? Yes.

Ive emptied mine out a few times and everytime I say to myself man I'm glad that isn't going into my combustion chamber. Will it affect performance significantly? No, but it's just like those guys who change their oil at 3K miles... it just gives them peace of mind.

If these same guys would increase their oil changes intervals to just 5k miles, even though Mobil 1 is proven to be good to double that, you'd save enough $$ in just one year to buy a good catchcan.

I agree on this but we are all over looking one little item. Besides carbon build up and moisture there is acid build up. Only a lab test can show you the difference over time. This acid build up is one of those things that is kind of hard to really measure. We cant really smell it, see it at , or feel it...but its effect can be a make or break thing. Its like a bullet proof vest. EEHHHH who needs it...its heavy, cumbersome, ugly, makes u sweat and the chance of it ever being utilized is about 1 in a million right. Right, until one day u are the million and now it means everything. Peace of mind, especially with anyone who invested about 30k on top of the cost of the car in things already, is paramount.

I installed a catch can on my car because I want added peace of mind that it provides. The device has proof to back it up, and I simply wanted minimize the effects unwanted oil causes. Some people are completely fine with the "minimum" or subpar performance in a sense. I've spent a good deal of money on my car, and I simply wanted to keep the car performing optimally "throughout" its life, regardless of how long I keep it. So, for $150, give or take a few, that was a small price to protect my engine, and possibly decrease maintenance costs down the road as well. The engine works great as is, and it's been said that the engine will last a long time without a catch can. However, to put it in prospective, the human body still runs on unhealthy food, lack of exercise, little to no stress management, and lack of proper body alignment, BUT it does not run as WELL. It may take time for the body to feel HUGE effects of running your lifestyle accordingly, but they can still be felt on some level. These problems are still occurring and progressively getting worse. I personally, am just not OK with that. I want my car and body to be running optimally my whole life. It is what it is, and some people see it differently.

I build all types of motors from antique exotic sports cars to chmapionship drag motors that we run Top Dragster with on alky......some are worse than others in consumption but all will enjoy better overall fuel economy if nothing else by not have the low octain tables kick in from detonation caused by the oil. Also, remember most dealer techs are only taught what the dealer needs them to know, not the complete understanding of all things engine related.

Lets address Super Chargers and oil in the intake air charge.

There are even large respected installers that claim oil in the intake charge is somehow "good".

Here is a picture of a Maggie intercooler after not that many miles running w/out a oil separating system:



Notice how in a short time the oil residue has coated the intercooler reducing its ability to properly cool as efficient as it was designed to. Now picture the rotors of the TVS blower that are persicsion designed with extrememly close tolerances for peak performance. This same residue builds up throwing the balance of and eventually causing interference between the rotors that result in shorter life and eventual damage.

This is just the BEFORE the combustion chamber carbon & gunk build up addressed in the above posts.

Now can anyone give an educated reason why this is good for any part of the blower system or engine?

Bring up anything you have been told or heard so it can be disscussed and the facts separated from fiction. This is your car and your investment.....knowing all you can is for your benifit.

Actually, yes I can give a reason it's good. And in my case you can't argue it.

If my Maggie fails sooner I can have a good reason to get a Whipple.

Where the hell did I post that? I'm not that nice.

I"m no expert obviously. But my gut tells me there isn't enough oil getting through to the pistons to detonate.

How many times per minute does each cylinder fire?

I put my blower on with 20k+ miles on my car. Yes, I had a lot of oil in it. I took pics and posted them up. I bought a catch can because of it, and I am NOT speaking as if I am an expert. But if you figure a cup of oil every 5k miles or so I'm not so sure that's goint to hurt anything. I can't see that the cilynders allow so much oil per stroke in as to cause a detonation condition.

I bought mine mainly because of my supercharger. Tracy's supercharger info was enough for me to play it safe when I did my blower. I got the catch can and so I'm ok. But also because I have been wrong plenty of times before and it is an inexpensive measure. I"m just thinking out loud.

Build-up of oil can't be good. But that's what seafoam is for.

And as far as the big car companies not making them......... why the hell would they make one? It's preventative for WAY after your warranty expires. (jk)
