I believe Jaigermeister has his up for grabz...
heehee I would sell it but I just got it:rolleyez: I got it from Ebay.
Here is what mine looked like after months of driving.
Britt got some really good pictures of it as well. About an inch thick layer of goop, with the rest under it, water and stuff. Yuck!
Torspd did you have any kind of filter material in your can?
Just a baffle on the lid.
hmmm, mine doesn't have a baffle on it, I have read to put in a green scotch bright pad to give the oil more surface area to stick to.....
Any recommendations in specific for one of these?
Yes. The kind that suits your needs the best. :top:
Lots of great info here! Thanks guys! Next mod will be catch cans for both the 4runner and Tacoma! (both N/A unfortunately)
I'm pretty sure no one has asked this tho I havent read every single post yet. What about on a stock N/A truck just closing off the INLET back into the driver side intake, and letting the PCV hose on that side vent to atmosphere (offroad) or into a catch can with no return line? (just an inlet and no return on the can) I actually already tried this yesterday after cleaning the throttle body and MAF sensor, to see how it runs and it almost seemed a little rougher, tho I cant really tell... The one difference I did notice was the "harley rumble" once off the throttle after an acceleration pretty much went away and I'm not really sure why.
The lovely rumble seems to be coming back today, but I came to the conclusion this would only be a possible good idea to do on shorter trips during the winter months, and way less of a chance of being one during a mild to hot day or night, as there is no vacuum from the intake system creating positive pressure on the pcv to pull that vapor out of the crankcase. Sorry to learn out loud here, I'm still a little unsure why but since I didnt notice any residue at all anywhere coming from that PCV hose I realized I was not a genius after all...
What you did was create a massive vacuum leak.
As yours currently is, the engine is sucking in air through the intake across the MAF sensor, which is metered. As well as air through the passenger valve cover across the engine, then through the driver side pcv hose, into the intake manifold. Which is unmetered. Ultimately creating said vacuum leak.
As well as making it harder for the engine to maintain proper air fuel ratios, which gives it that "rumble." The end result will be a check engine light.
There is a picture of mine which is quoted, post number 217. This is effectively the same thing that you described. That is incorrect routing. That is back when I didn't understand what was going on.
No mate I had the inlet on the top plugged, completely blocked off with a screw and some tape, and the pcv was just venting through its hose line. The rumble noise is a normal good sound as far as I knew that sort of went away for a day once I did that but it did come back, its all hooked up now tho. I had to mess with it myself to figure it all out in the end.
I still wonder whats really the point of having a return line on the catch can unless that really is needed in order for the pcv valve to do its job..
I cant imagine that it would pull anywhere near the same pressure on the pcv valve as the stock setup tho, especially for a can with a breather filter fitted right?
