You're gonna need some bigger disk's to stop that hybrid you're gonna get
Oh yes, we know you want to...
What are people cleaning these with?
paintbrush to brush it of; pressure hose, any tips and offerings are greatly appreciated by all and sundry
Volvic. Stopping the EGR (Exhaust Gas Recirculation) means that instead of the ecu feeding exhaust gas back into the inlet to reduce emissions, all the exhaust gas goes straight out the exhaust. No problem with that.
Regards the engine overfuelling if the EGR is deactivated. Nope, because fuelling is based on the engine running without EGR, and it's only in certain circumstances that the EGR operates and scavenges exhaust gas into the inlet. So in effect, no EGR is better for fuelling, although not for emissions.
I bought a device a while back on ebay for about £10. Once the pipe was disconnected from the EGR and closed off a new pipe was connected to the EGR which fed into a snmall brass device. The device had an input and output aswell as an adjuster bolt which compressed a spring and a ball bearing which enables the boost to be manually adjusted. The other pipe goes somewhere else with a T-piece to connect to another pipe and the wastegate if i remember correctly, although dont quote me on this lol
Looks pretty clean that...good fuel and oil must be doing its job Chris.
The flap you can see there is the anti-shudder valve. The EGR is futher down the pipe, underneath the "flying saucer". The buildup of crud only happens downstream of the EGR, in the inlet manifold, where the oily CCV vapour in the charge meets the sooty hot exhaust gas.
