Ahh that's still on my to do list.. I have a catch can to fit at some point..
when I said I thought the egr was responsible for the mess and carbon build up in the inlet side obviously the oil came from that side of the engine but I'm sure the exhaust gas just made it worse..
You are most probably aware that low pressure egr is now well established in the automotive industry..so regardless of load conditions on the engine there is pretty much always a flow of recirculated exhaust gas..

Anyway I have other matters to see to..
I had a warning light this morning..I'm hoping it's not the start of a load of bother..😫🫣👇

Fuel filter, Tank pump, HP pump, VCV or fuel rail pressure sensor are areas to check.

I am personally convinced that deleting the EGR and adding a Provent to the breather circuit is a simple way to extend the life of your engine by a significant amount.


I totally agree with Blackwolf, with the addition of mapping out and removing the DPF on the 2.2.

As for totally removing the EGR and cooler, unfortunately it’s an MOT visual inspection item. So mapping out, leaving in situ, blanking off each side of the cooler and removing cooler pipes and joining together is the most prudent solution. Also putting a faux DPF/CAT canister on the downpipe If mapping that out is needed as it is also a visual inspection item.

The main issue will happen if the basic smoke test is changed to monitor small particles and /or readings are taken from the OBD2 port regarding EGR and DPF. These sort of tests are conducted in other counties so a precedent has been set.

Cheers Ian..
I've had a quick look and got this.
I've cleared the fault but I'm not holding my breath that it will stay away..😫

I have similar issue. Coolant loss through expansion tank. I removed the egr cooler which was found to be leaking. Replaced with a new cooler and valve. Still failing a co2 test so suspect HG is leaking as well
Question is what to do next.
I am thinking replace with brand new engine. May sound overkill but at around £4k would surely be worth it. I am tempted to start stripping the engine to find the issue and attempt the repair with the worst case scenario being the new engine.

Does anyone know if the HG repair can be done without de gassing the AC. If it does need to be de gassed and removed then I would want to do this before I start stripping as I can drive it short distances in its current state.

head gasket
I would think you would not get away with out taking any air con pipes out the way, To take the cylinder head off you basically have to strip everything out the engine bay to get at all the nuts and bolts!

That’s what I thought. More hoping someone would say otherwise.

Unfortunately a leaking EGR cooler can cause the head gasket to fail, I suspect that’s what happened to you.
