I just received my Elite Engineering Catch Can this afternoon and installed it as I understood the directions. Can anyone tell me if this looks incorrect?



Also, does anyone know what this nut and stud are for? There seems to be some kind of thick insulated metal flexible cable attached between it and the PCV valve? Maybe some kind of safety bracket? Is this necessary? Plus, I noticed the other day that I was getting some of what looks to be oil blow-by on the leading right forward flange of the engine. I cleaned it off, but noticed it had built up again in the past week. Any idea where this leak might be coming from?

 

i am at work, so no reference, but i think that nut is for a ground
nice blue and green hoses- sombody will be asking where they can buy those

 

The nut was holding the old PCV holder/socket and the reason it's attached to the engine is to provide a heat source for the PCV. Part of the emissions design.

 

Your hook-up looks fine for a pre- 03 LS1

 

You can get the colored hoses in any version of Adobe Photoshop - that is where I got mine.

 

I was going to point that out.

 

This has been discussed quite a bit before on the forum. This is what made sense to me and what I did on mine.

If you run your blue hose to the bottom of the catch can and the green hose to the top of the catch can, you can use gravity as your friend. This way, for the oil to get back to the intake, it has to go UP the length of the catch can and through the fitler media. The other way, if you forget to empty the can, the oil level can be right at the bottom fitting which would make it easier to be pulled back into the intake.

I emptied mine last week after being on for about 2 months and it had about an 1/8" of oil on the bottom so it is working for sure.

I installed mine after seeing how much carbon was on top of the pistons when I did my head and cam swap.

 

What you say about swapping the hoses makes good sense to me.

I am not sure what the maximum flow-rate would be through this 3/8"-ID hose in a worst case scenario and what the resulting velocity would be? If it is fairly high velocity I could see where reversing the lines may be a positive thing for sure since as the the oil drips down to the lower compartment from the mesh it may be partially diverted into the lower outlet hose the way things are now. Also if the lower hose were the inlet, the oil would have to slam into the far wall of the cylinder first (if there is enough velocity) and would have a tendency to run down to the basin. As it is right now, ALL the oil is forced to go through the mesh which means as it "drips" into the lower compartment some of it may be "swept" into the outlet line before it ever comes in contact with the collected liquid at the bottom. However, if there is virtually no velocity in this system, then it would probably not matter. There is apparently sufficient velocity to carry oil all the way to the intake manifold without the catch can - so this may be worth looking at? This also assumes that some of the oil being carried ina liguid state (which may not be the case)? If it is a super-saturated mist, then probably cooling it down would help. I guess the trick is to reproduce the same environment that the Intake Manifold posesses - but upstream of the Intake - apparently the Intake Manifold is very efficient at changing the suspended oil to a flowing state.

I sent these same photos to Jeff at EE earlier today to get his input and he said everything looked correct for a 2001 LS-1?

 

Just my 2 cents, but you will catch ALOT more oil if you were to mount the can in a place where it can stay cooler. The hotter the oil, the thinner it will be & easier it is to be sucked out of the can. Mounting the can to the head does look good & is convenient, but the can stays red hot! I have done this & it DOES work!
