Everythings going wrong! EGR pipes and sticking inlet manfold flap valves link?

[Loz]

I was just researching this on the forum but can't see that anyone has actually fitted one. I assume a catch tank on the crankcase breather pipe wouldn't stop the build up grom the egr, just less vapour in the inlet manifold from the crankcase?

Correct, would also need the EGR blanking.

May have to look in to an egr delete to keep the new manifold clean. Believe it also needs a remap on the t6?

Update. New inlet manifold fitted but still getting the fault p2006 or p2004 fault codes. Actuator stuck open or stuck shut. Driving fine though. Any ideas?

Did you check the vacuum operated actuator?

I don't have the tool to pull a vacuum but after doing some research it seems it could be the valve that pulls the vacuum so going to take it back to the garage tomorrow and ask if they checked this before replacing the manifold!

Indeed, it could be as simple as the filter in your photo below the solenoid being blocked.

A large syringe will pull enough vacuum to activate it.

New N75 valve fitted and all good it seems. Who knows if the manifold was the cause of the fault but it certainly needed changing with gunk approx 5mm think built up inside.

How can this be acceptable for a 2016 with 100k. I'm thinking maybe the EGR was stuck open for a long time under a previous owner (was changed in 2020) causing an excessive buildup, or it it really just poor design?

It's due to the engine breather going back to the inlet. Fit an oil separator to avoid the inlet and egr problems.

I'm looking into doing it soon.

Where does the breather enter the manifold?

Turbo inlet pipe

Turbo inlet pipe

So breather passes in to turbo inlet pipe and then in to the manifold through the throttle valve?

 

[DXX]

Yes exactly

Got a link to what you are going to fit? Looking to avoid this problem in the future. Thanks

Oil Catch Can For Euro 6 Engines

The dirty air comes in one and through a wire gauze filter in the centre. Oily residue collects in the bottom and clean(er) air goes back into the intake. I just run a pipe down from the bottom connection to a wheel arch and put an in-line tap on the end. I just drain it whenever I think about...

I ordered one of the provent 200 copies, will add a tap into the drain line . Not sure where it can be mounted but that's for when it arrives.

It doesn’t hurt to mount it with a long feed and return hose. This allows some cooling of the oily gases and will aid the oil drop out into the separator pot.

 

[Loz]

I was thinking it would mount behind the air box?

 

[Fluff34567]

Possible, when it arrives I will check. Maybe a 3d printed bracket is needed.

Might be a bit tight as the provent copy is pretty big but let's see!
