EGR Delete/Allard Pipe/Catch Can

[Jimski]

Hey all!

I'm getting a little confused about the above and tbh, maybe this could end up as a sticky for the definitive guide!

I have an Ibiza FR TDi PD130 'BLT' engine;

I have reduced the EGR with the 9mm gasket, but my attention has been drawn to the Allard Pipe, now..... i believe this to remove the valve altogether, along with the anti-shudder valve and the dash light will need to be mapped out?

If the Allard Pipe is installed, the engine will still breath through the intake system as normal, and things will still get gunked up??

So........my solution is.....get a friendly SCN member to reduce my EGR through VAGCOM to the minimum values and continue to use the 9mm gasket AND buy myself a shiny catch can to stop 'gunking' and then in the 'summer' (i use that term loosely) il strip off the pipework and clean it all. Then it will stay clean, with the catch can.

Am i making sense?? Just wanted to make sure that the Allard Pipe didnt really affect a gunky intake system, and in fact i just need to buy a catch can.

Thanks, hope your headaches arent too bad

The combination of exhaust gases being recirculated along with the fumes from the breather cause the EGR and inlet manifold to gunk up.

I replaced my EGR valve with an EGR replacement pipe, took off and cleaned the inlet manifold, stopped the breather fumes from getting back into the intake and I still have clean pipes 10,000's of miles later

Legend, do I definately need a delete pipe?

i.e just continue with a reduced AND get a catch can?

Will this give me the same effects as you in that my pipes stay clean?

Seeing as its the combination of the two, you might be ok with just a catch can, and cleaning everything else up.

 

[Jimski]

I'm going to be real pain, but have you got a picture of your engine bay so I can see the breather you stopped feeding back in? I spose il have to find a suitable blank plate for the intake too.....

The breather is located on the top of the engine, and feeds into the intake pipe via a short piece of pipe.

Have a look at the thread:

It shows the 110 non-pd engine, but no. 7 is the breather hose. On the PD, the breather hose goes to where no 8 is, if you see what i mean. The oil filler is on the right.

The intake can be blocked off with a simple plastic cup (a door stop I believe!), which I purchased from B&Q (recommended by another on here can't remember who).

 

[Jimski]

Ahh ok, that makes sense, my oil filler is on the other side, but thats quite obvious!

I shall look out for a bung and get measured up for some silicone hose to the can!

Cheers for the help mate,

I used something like this.

Good shout, cheers dude, +1 beer token!

You using a catch can?


Jimski

 

[trebormint]

Er, I should say I am. But no comment!

Is a catch can with 15mm fittings likely to do the trick? I cant get out to measure


Jimski

 

[Jimski]

Ok so the catch can was a PROPER faff, theres nowhere to tidily secure it at all, the crank outlet points towards the oil filler so theres little room for pipe reducers etc!!

I've seen on a couple of internettings that there is a bespoke catch can? Anyone know about this?

beens no one replied theres a company called mann & hummell but theyre expensive

im looking ad doing this myself (already got can from about 2 yrs ago just never ar$ed to fit it

if you get hoeses long enough you can fix it somewhere secure

i also read that people put scourers wrapped in tights in the can to make a filter

I'm not sure about this, but doesn't the catch can need plumbed back to the inlet, rather than blocking the inlet off? I know I've done it this way, but I've never seen anyone say it definitely needs it on a diesel. It needs it on the lcr and I assumed, if it needs it, then so do I.

 

[Andrewcupra TDI]

theres two ways to do this you can vent to atmoshphere , but you get steam in the bay , and sludge drippers

or you can plumb it back into the system after being filtered out via the catch can , it catches filters and lets cleaner air back into the breather system helping less sludge /carbon build up in the system

oil burners dont require the same pressure stabilisation as petrols so you can just vent it to atmosphere without a problem.

Does a diesel actually need to vent this oil then? Could you say, just block off the outlet on the rocker?
