Oil catch can but why?

Ha!. I have filled my window washer tank with olive oil and turned the sprayers away from my windshield...such a blast "washing" my windshield in traffic...

 

The size for the ADD W1 Catch Can is ...... 2mm X 60mm Metric Buna-N 70 O-ring. Model # N2.00X060
I got them from
"The O Ring Store LLC" online.
Address is 1005 Warner Ave Suite A, Lewiston ID, 83501

Without this you will have a vacuum leak and throw codes.

 

Although Maricopa County got whacked by the Feds for removing SMOG equipment on some of their cars - this was when I was in college in the early 80s.

 

Huh, guess I'll have to ask one of my friends who used to work at Lycoming Engines (Avco) if this is true.

 

This is the most false of any argument not to use one.

OE manufacturers cut corners to save money ALL the time, and a catch can requires routine maintenance to operate as intended. If someone forgets to empty the catch can it totally COULD screw the engine up which would be bad, however, installing one removes oil vapors from crankcase before they get recirculated into the intake. Manufacturers accept that while this is undesirable, it doesnt warrant creating another interval maintenance step for people to regularly defer or skip altogether, since this one can do significant damage if left unchecked for too long.

So using a catch can will help the engine's running by removing these vapors so they dont coat your intake track, maf, and upper portion of cylinder with sludge. It gives you a very slightly more pure fuel charge by removing a small amount of heat and more oil vapors from the fuel charge.

 

All I'm asking is for you to prove it. Show me internal pictures of a NA engine after 100K with, and without a catch can. If you can do this and it shows it does absolutely anything to help, I will gladly eat my words.

 

There's no way to do that because there are several factors which would affect the cleanliness of the engine to a greater degree like quality of oil, frequencies of oil changes, quality of gas, location (humidity/salinity), etc there's a million factors that affect it. The only proof I can give you is that without the catch can the car runs and with it the car still runs so it hasn't negatively affected operation. While the catch can is in use it catches something inside it but without the catch can air on the same track is free to flow into the intake. It doesn't take a scientist to figure out that the stuff in the catch can would have otherwise been deposited in the air intake and then sucked into the engine. Is it going to look cleaner? Probably not, because an engine is still full of explosions which release carbon deposits as a byproduct. I can't give you a definitive answer with data as to whether it does enough to affect performance in any measurable way, but its pretty common that people foul their maf sensor eventually without any mods to their car. A catch can might increase the interval at which you have to clean your maf or maybe eliminate that as a maintenance item entirely.

 

An honest answer. Thank you.

 

I have one on my F-150 w/ecoboost. I added it because of the turbos and intake valves being known to carbon up. Its amazing the crap it catches.

The new ecoboost engine added a injector pre intake valve to help wash them down. Thus keeping them from carboning up.

 

I really liked my 2016 F150 Lariat 4x4 with 2.7 during the 13 months I owned it. Excellent engine power and torque, practical room and nice features were enjoyable. Frozen locks and doors that wouldn’t latch in freezing weather along with a stuck blow off valve? causing check engine light to illuminate were items that were fixed under warranty and will hopefully perform for the person who is driving it now.
It had been brought in to the dealer twice, each time for several days as extra parts were ordered.

It also started stumbling a little at stoplights while idling at around 11,000 miles.

I purchased a borescope, removed the intake pipe at the top of the engine, held open the flap and fished around to various cylinders. The carbon buildup on the back of the valves and stems at around 12,000 miles was interesting to see.

I decided to sell it at 13,000 miles when I just happened to be looking around the engine compartment and decided to check the air filter. When removed, the back side (or clean side) was fouled with oil (Mobil 1 since under 1,000 miles) which was surprising. I guess that either it was still not functioning properly or the oil was just from PCV mist circulating in the system. I had read that when lifting off the throttle, the intake flap closes and there is still air under pressure in the system, so it possibly backed up to the outside air intake. The mechanics reading this could probably inform us about it.

I removed the lower intercooler inlet pipe and found there to be a bit of oil inside. How much is too much, I do not know. I’ve read that, some say that some oil is ok, and other people say that some oil is not ok.
I don’t know. I tried at length to research it, and of course read many differing opinions. I’m not a mechanic but I take care of my own maintenance.

Posting pictures of oil running out of lower intercooler inlet, fouled air filter and carbon buildup.

I had been thinking of purchasing a good catch can figuring it couldn’t hurt, but then traded it in on the Tacoma. I had also thought about purchasing a newer model F150 with the redesigned motor, but a Tacoma is what I had been looking at before purchasing the F150.

I owned several Ford Trucks before over many years and I guess I had just been lucky in that I never had any problems and not even a single squeak, rattle or buzz in any of them.

My Tacoma is solid at 2,000 miles and it’s dialed in to be quiet now. Like I keep saying, just check your fluids.

 

are you considering a catch can for the Tacoma?

 

People will alway's argue about stuff, Ford vs Chevy, Smith & Wesson vs Ruger etc. I feel better knowing I am not running that crap through my Intake system.

 

Just a cheap borescope with color screen purchased with coupon from Harbor Freight. A neat tool to have if you want to check your valves or see into other hard to reach places on your Tacoma.
Checking out the valves on the 2.7 turbo.

 

No, I see no need for the Tacoma. With direct and port injection, the valves should remain squeaky clean.
I never worried about it on any vehicle before, but, like others have said, it could provide some benefit to a direct injected only engine, especially a turbo direct injected one.

Even on the 2.7 turbo, the intake tract at the top of the engine was completely clean and free of oil. Go figure. Seems that over time, either some fine oil mist is getting in there and carbonizing the intake valves, or,
the valve timing was allowing some exhaust gases back into the intake due to keeping the valves open slightly longer. It can be adjusted with updates. At least that is what I read.

Edit:
I’m sorry, I meant to quote the above asking if I was considering a catch can.

 

It seems that if your valves are clean and your intake is clean along with having clean spark plug tips then there’s not too much to worry about. I think that a lot of the stuff caught in the catch can is water vapor, which thru cylinder combustion will easily burn off. That’s how the PCV system is supposed to work.
Of course, in a dirtier running turbo engine it might be catching more oil.

I’m not against catch cans. I like to do maintenance and tinker with my truck!

 

So here we are again with the age old question, to catch or not to catch…

But here’s the thing, what is it that we’re trying to accomplish??

Me myself, I generally keep some vehicles for well over 100k miles. My longest lasting 280k trouble free miles over 15yrs, which is about the limit I would want to own one without doing extensive and expensive renovations such as prime & paint, totally new interior because as much as I love the new car smell, I hate the old plastic smell ugh!
And of course add new sound system, gizmo tech, all new rubber hosing under hood, suspension and on and on.

SOoo how would can catching help me since I already get what I want without any help from a trash can?

And since it would appear that the pcv system is already taking at least some of the trash out, I think I’ll pass.

Cheers!

 

Not here to argue one way or another. I have one one my second gen. For anyone who is going to get a catch can, the Moroso catch can is super nice.

 

A catch can on a daily driver......LOL. Hey, whatever you wanna spend your $ on.

 

Don't argue over it. Either run one or don't. I run one and always will.
