PS pulled my EGR pipe off the other day, (it's just two bolts at each end), very easy, and don't like what I see- a lot of gooey black crud in the pipe, and inlet manifold.
I'd love to block the EGR but suspect it would immediately throw fault codes and possibly cause other problems, so at this stage that's a no go.

So it seems like your solution on page 3 is currently the only "compliant" way to address this problem (that I've found anywhere for this engine) Could you share your catch-can setup in more detail so we can reproduce it? (can model? hose/fitting dimensions? filter media?)

Could you also post some more info (on a new thread) about what your seeing in the EGR system (pictures? mileage?)

Looks like you already did! (link here ->) Any way to block the EGR?

Be patient please guys.

Currently away from home for the next few days but I probably have photos on my iPhone somewhere, so will see what I can dig up.
Can't give you a lot of detail on the actual can, it was a cheap one from "Supercheap" car accessories shop, which is unique to Australia. However I'm sure somebody like Pep Boys would have something similar.

Re: oil catch can

Hope you guys appreciate this, LOL, quite difficult on the iPhone.
:-)

I used basic catch can from "Supercheap Auto" (unique to Australia, but sure to be available at other auto parts suppliers in the US like PepBoys etc..)

Plus 3/4" heater hose, from camshaft housing outlet to catch can.
(Very tight fit on to the engine, hose clamp required to hold in place.)

Plus 5/8" heater hose from catch can to original hose fitting. No clamp required.

Plus cheap stainless steel scourer pads to "fill" the catch can with SS mesh, to catch oil droplets.

STEP 1. Disconnect hose from the fitting on the engine. You just press the plastic fitting and the hose pulls off easily, complete with a plastic fitting.

Step 2. Connect 3/4" heater hose to engine.... Very tight fit, needed a hose clamp. It feeds up to the catch can position, running behind the air cleaner box.

Step 3. Disassemble the catch can, and fill to the brim with (cheap) stretched out stainless steel scourers. I had to rotate the top on the can to fit beside the air cleaner box before re assembling.
I actually stuffed in a few more stretched out scourers through one of the hose fittings after refitting the top, so the can was really chock full of SS mesh.

Step 4. 5/8" heater hose then runs around in a loop and fits perfectly on the plastic fitting on the end of the existing PCV hose, jams on and stays there nicely with no clamp required whatsoever.

Step 5. Assemble together and hose clamp the hoses on the can, catch can fits neatly beside the air cleaner box, tilted at about 45 degrees.
To empty I undo the two hose clamps and remove the can to drain it, via the threaded drain plug.

Nothing from the factory is altered, and it literally takes a minute or so to return to original factory condition, potentially important for warranty if your dealer wants to be a PITA.



Here is where the PCV outlet is, left camshaft housing. Squeeze the plastic clip, and the hose comes off. The 3/4" heater hose is then a very tight squeeze on, held with a hose clamp.




Here is the cheap catch can with the top temporarily removed, to fill with stainless scourer mesh. I then reinstalled the top and fed even more stretched out scourer in thorough the inlet fitting, to thoroughly fill the can with mesh to catch the oil.



Final installed position. It sits here snugly with no rattles, no bracket required. I do need to remove it to check the air filter though- just two easy hose clamps, takes only a minute or two.




And the final plumbing connection. Catch can outlet (5/8" heater hose) runs in an arc around and is a neat fit onto the plastic factory fitting on the end of the PCV hose, no clamp required.
Nothing hacked into, no factory hoses cut or modified, no restriction, the can can be removed and original plumbing plugged in to the engine outlet : ie: returned to factory condition in a few minutes.





Edit:
PS incidentally, I forgot to add that where the 3/4" hose passes behind the air cleaner, it was a fairly tight squeeze. With the issues I (and many others) are still having with cracks in the rubber gasket on the disposable air filter element, (both the factory filter and the dealer's replacement) I wanted more room to make it easier to check the filter element.
I suspect this problem is VERY widespread. Most people wouldn't check and therefore wouldn't know that there are obviously a huge number of faulty filters out there.
See here:

I have subsequently moved the electrical relay box behind the aircleaner box back a little (by re drilling holes in the bracket, to give a little more room to open the air filter box.

Thank you for your post. How many miles (Km's) did you drive with this solution in place? Any codes?

It's been in place for about 3,500klms so far.

Absolutely no error codes, and quite frankly, I don't see how there ever could be.
I was at great pains to avoid any restrictions. There are no right angle bends (elbows), no small restrictive adapters, and no part of the setup is more restrictive (ie: smaller internal diameter) than the original plumbing.
And finally the SS mesh in the can is also virtually no restriction compared to some of the other filter style set ups. I knew that a few others had had issues and was quite determined to avoid restriction and therefore avoid any error codes.

The only thing I do not know is how much oil is still getting past the can. However the outlet hose is FAR less oily than the plumbing (rubber hose and inlet to the turbo) was previously.

Hope that answers questions.

PS incidentally, I forgot to add that where the 3/4" hose passes behind the air cleaner, it was a fairly tight squeeze. With the issues I (and many others) are still having with cracks in the rubber gasket on the disposable air filter element, (both the factory filter and the dealer's replacement) I wanted more room to make it easier to check the filter element.

I have subsequently moved the electrical relay box behind the aircleaner box back a little (by re drilling holes in the bracket, to give a little more room to remove and refit the air filter element.

Re: oil catch can

This guy seems to have approached the problem by using pressure to assist the catch can. That should negate the drop caused by the resistance of the can. I wonder if this approach would allow a ProVent to work without throwing codes?

He put a lot of thought into it that's for sure. I can't help but wonder if he trashed his engine with adding Lucas Oil Stabilizer to the oil? That's one thing you don't want to add to an engine, especially when the warranty is still intact.

We do appreciate it! I'll go look for the catch can.

Could you repost when you are able? It looks like only one of your pictures attached correctly.

Oil brand/type is irrelevant.


As for people sharing "fixes" from Australia, pretty sure Australian PCV systems are different than NA models.
