Oil catch can?

[Silverado-Hareek]

Whew boys, I spent he whole morning reading all the posts! Me old haid is spinning. Here's my conclusion, correct me if I'm wrong. I thought I was one time...

 

Which truck maker does not use direct injection? If none, I'll keep my 13 year old truck and keep fixing what breaks as needed.

 

I have come to loathe direct injection engines. What a stupid engineering system! Valves getting that gunked up because of it?!? Somebody mentioned Toyota developed a system to send some fuel over the valves to keep them clean. So, makers know this is a serious problem.

 

I'm wanting a new truck, but have decided to try my best to not get direct injection.

 

Ok boys, tell me wha' I'm missing.

 

Yeah that was me I think that said Toyota had developed a system that sprays fuel on the backside of the valves every so often to clean them. The problem is I'm having a hard time identifying which engines/models have this system. If the Tundra has it, I would definitely keep my eye on it to see how the reliability is over the next few years. Other than that, I don't know of any manufacturer that has addressed the problem with valve buildup. Any consumer with a direct injection engine should consider the BG induction service every 15,000 miles at a minimum. If you can throw a catch can into the mix, even better.

If you had a vac leak big enough to hear, you'd more than likely have a check engine light on, along with some very poor running.

Ya no engine light is on and it runs fine and still maintain good gas mileage so I thinks it's fine just was wondering

I do not hear any kind of vacuum noise from my setup. Might want to double check your clamps and make sure they are in position and tight. I know the one coming out of the valley was kinda tough to get tight with where it was positioned.

Got my Elite Engineering can installed today. Thinking about a different way to route the top hose as it goes down right around the oil fill cap. Was originally going to put it in the spare battery tray but didn't want hoses that long running over there and think mounting it to the brake booster cleaned it up a little. Also, the throttle body was a mess after only 8k miles and the shroud that mounts to the throttle body was full of oil. Definitely a good investment here!

That's not good the hose running over the oil filler cap to the intake, why don't you try routing it alongside the hose coming from the throttle body and then route it up the valley it would look much cleaner, off course you will need a new hose. Just my 2 cents.

does anyone know of a warranty issue with this modification?

i know its not a very in depth mod but will GM give you a hard time for this mod when coming in for service

[BuyAmericanIron]

A catch can will not void your warranty unless it somehow causes a problem.

Just from the nature of what a catch can does, I can't see it causing any issues. It's just a little longer path from the pcv to the intake

What my car has caught in 3400 miles

 

 

Mostly moisture

Wow and I though I had alot of moisture! So much water it didn't even turn white there.

[RyanbabZ71]

It was barely anything

The amount of fluid being trapped in the can is being greatly reduced by the rising temperatures. During winter, I must drain the can every 1000 km but during the summer 8,000 km.

Can anyone explain why this is? Summers are more humid, the warmer air can hold more moisture, and people complain about dry skin and use humidifiers in the winter. So it seems it'd be the opposite but it's obviously not.?????

Condensation holds MUCH more liquid than humidity. When its cold and your engine is much warmer than the air around it, condensation forms.

Condensation IS liquid.

 

As the temperature of air rises, it can hold more water vapor before it becomes 100% saturated (dew point). The table below shows a dramatic difference in the amount of water air can hold, based on temperature. (1 kg of air is about 27 cu ft and about 28 grams to 1 ounce)

 

 

When the air in a crankcase is heated, it can hold more water vapor (humidity) than cooler air and it absorbs water vapor out of the air coming into the crankcase. When the air in the crankcase and the crankcase itself cool down, the water vapor forms into droplets or condensation. When you heat the crankcase again, the condensation goes back into the air in the crankcase and is pumped thru the PCV.
