So pill bottles don't make good PCV catch cans....

[kwtorbe]

Yesterday I made a pill bottle PCV catch can. I used a small translucent orange pill bottle, 2 brass fittings from an old radiator, alittle tubing, and sealed it with silicone.

Today was my first time to drive with it on. I checked it after work and it looked fine. Then when I got home and checked it..... The bottle had been sucked in....I am pretty sure it is more due to the heat than the vacuum of my engine. (I tried to attach a picture)

Anyways just thought I'd share.... Next PCV catch can will be located further from the intake manifold and probably alittle bigger (I made it small because I didn't want to hurt the engine's vacuum but that doesn't make a whole lotta sense anyways....)

do those help fe at all i dont really get how they work eather

I don't think they really help FE that much. I know they filter the oil vapors out of your Positive Crankcase Ventilation system so that you don't burn them in your engine. I think they help cut back pollution some and I know oil isn't good for combustion. I tried it because I think every little bit helps.

The goal is to keep the junk from collecting in the intake manifold, injectors, top-end parts, carbon buildup and other FE-robbing stuff. It's a preventative measure.

sweet ill show it to my mechanical friend maybe he can do it for me

Heat probably softened it, and vacuum did it in

I haven't noticed a difference in my FE, but the car runs a little smoother now than it did a few months ago and has lower emissions, which is always worth the effort.

Haha, the same thing happened to my water injection tank Heat + soft plastic + vacuum... not a good mix

what does it mean when u are getting no oil in the can

No blowby. That is a good thing. But it seems like every car would have at least a little bit.

Or, your can is not working right. :-)
