My new crankcase evacuation system

[Calan]

I think Eric is trying to rival Mitsu for packing crap into tight places.

Damn that engine bay is CLEAN. I was gonna find a speck and circle it so I could make fun of you about it...but I couldn't find one.

BTW - What is that screwed into the drains?

 

[turbosax2]

I have all the bungs plugged so I don't get the inside all cruddy while I'm wetsanding them.

 

[snowborder714]

How about the whole top of the shock???

NPT plugs with teflon tape.

Looks great, Eric.

HOLY CRAP! How did I miss THAT! WTF

.oO I wonder if Paul is mad at us for taking over his thread yet?

Furious.


I just drained my catch can again 2 days ago, and drained quite a bit of oil this time around. I'm not sure if it had to do with me turning the fitting in the intake pipe around 180* or the fact that I was running 47 psi on a warped head the last time it ran. Either way, I wish I would have datalogged it again with the fitting turned. Most importantly, still no oil getting past the can.

Cool deal Brian...

Did you mean no oil in the intake? Have you had a chance to log the CC pressure by any chance?

Thanks for the update!

No oil in the intake as well. The smaller can I had I would collect a small amount of oil, but with the dual in/out there is zero. I was kind of shocked. The system works very well. Great job!

 

[Calan]

I finally got around to making and installing one of the new dual-inlet cans for my own car rolleyes, and got some data this morning on the way to work.

The most crankcase pressure I see is .2 psi during cruise. During boost (about 30psi), it stays around -.6 in/hg, and occasionally drops to -1.1 in/hg. It never did go positive during boost. I removed the PCV valve side of the system, which probably accounts for the slight positive pressure during off-boost driving and in between shifts. I'll most likely be hooking that back up in the near future.

I'm still fighting with some spark blow-out issues, but once I get that under control I'll log it again and post some more data, along with pics.

I know I am adding some late information, but having your slit is the correct method of flow.

An example I will use is the heatsink extenders that Innovate makes for the LC-1 WBO2 sensors. The hole on the side must be oriented towards the exhaust gases rather than with the flow.

After looking at that catch can you run Paul, what keeps oil from entering the intake within the canister? I see that the vent lines from the valve cover are very close in relation to the fitting for the line going to the intake. Is there baffles welded within the canister? Steel Wool acting as a baffle system? Just curious as I am trying to build a set-up myself, canister and all.

Check Calan's thread regarding the internals of his catch cans.

Check Calan's thread regarding the internals of his catch cans.

It uses a coledence ( I have no clue how to spell that) filter. Zero oil passes through, well maybe .01 %

It's the best catch can on the market. I swear by it.

Calan's catch cans use internal filters as well as a baffle between the inlet and outlet fittings.

What filter?

 

[Sirnixalot]

if i were to loosely replicate this but keep the line going to the intake manifold would i be able to use a fuel check valve like the one below or would that leak?

though its not quite as baller as the stuff i see going on in here here is what my setup consists of.

I am capping off the intake manifold line and running a single 7/8 hose from the valve cover to an ebay catch can, which also has a 7/8 tube going down the middle of it. This tube has 6 holes drilled in it and is surrounded with coarse stainless scrubber stuff. I did not put any baffles behind the hole but the hole is right next to/above the HLA restrictor and it looked like it would block most of the hole from the cam lobes flinging oil

The 2 other fittings will run to the intake and enter at an angle with the notch cut like 99gst_racer has done.

Anymore updates on this, logs etc..?? I think I'm going to run this same setup on my build. It looks clean and bada$$

Well I received my single large catch can a while ago. After being given the run around at a welding shop, I finally got the fittings welded in the valve cover, brackets welded on the catch can and bung welded into the intake pipe. I took video of the whole process so stay tuned for that link. I plan to edit and compose the video by this weekend.

Anyway here are a few pics of my setup. This pic shows a shot of the can sitting in the cruise control spot on a 1G. You can see that the nipple of the old breather port was taped and replaced with a hose barb fitting for data logging. Unfortunately the only vacuum cap I had was blue.

Here is another angle. The shine that you can put on something with your own hands is just amazing.

Third picture shows the mounting brackets and points. I used a piece of stock aluminum to make my own brackets. Then I used two existing holes (one on the frame and one on top of the tranny mount) to mount the can. All this will be in the video. Just noticed that I left a spare piece of electrical tape on the fuse box.

The next picture shows the routing of the -10 AN line to the intake pipe. It goes slightly towards the frame (Never touching), under the intercooler piping, Clearing the shifters of the transmission, and finally bolting to the intake pipe.

This is a picture of the bung in the intake pipe with the only blue and red fitting in my setup. Call me cheap but those things get expensive.

This next picture is a shot of a spot that usually has a pool of Brad Penn oil but ....... uh oh ..... could it be..... Yes squeaky clean it is.

This last shot just gives you a good view of what it looks like in my engine bay.

Let me know what you think and stay tuned for the video of this install.

 

[99gst_racer]

Looks good.

 

[TSIfreek]

Very nice!

 

[ktgurl87]

I personally cannot stand how squeaky clean Paul's engine bay is.

 

[BoostedBeaver]

99gst_racer Looks good.

TSIfreek Very nice!

Thanks Paul and TSIfreek. Paul I was told that this has become more of a reference thread for these cans, so I posted it here. Just sharing my info and other mounting options for the can (even in a bay that still contains a ton of stuff).

ktgurl87 I personally cannot stand how squeaky clean Paul's engine bay is.

Exactly what I was thinking as I scrolled through the thread.

 

[92AWDHX40]

Looks good, im still working on my set up.

 

[Scott McIntyre]

Looks good Robert.

It that two -10AN lines feeding the catch can with only one -10AN line exiting? I would think that you'd want at least two lines going to the intake pipe (or one huge one that can outflow the two feed lines).

Looks like two -10's and a -12.
