I’ve been thinking about blocking the egr on my car for some time (in fact I may even have mentioned it here before). With the new exhaust fitted I’m thinking it would probably make sense to get the car dyno tuned with a focus on torque & economy, (particularly as since it was fitted I noticed it blew a little black smoke when my wife gave it a few gentle revs from idle).
I suppose that if I were to do the egr block it would probably make sense to do it prior to a dyno tune? yes/no?
There seems to be plenty of info available on blocking the egr on 3 litre models, but very little for the 4.2’s. However our good mate Mudski, among others sells the plates to suit 4.2’s so I guess folk find it a worthwhile thing to do. I’m particularly drawn to claims of improved fuel consumption & cleaner, longer lasting motors. I do harbour some ambivalence about making the car more polluting but on balance am prepared to do as many others already have. I’ll live with the hypocrisy!
What I would really like is a pictorial ‘how to’ if someone could manage this for me. Send it as a PM if uncomfortable about putting it on the open forum.
There appears, from what I’ve read, 3 things to do.
1. Fit a blanking plate. Sounds simple enough - a pic of a TD42i with location arrowed would be good.
2. Remove an EGR actuator (butterfly valve?) - a pic showing location of this actuator & instruction on how to remove it would be good.
3. Fit a catch can. Does this apply to the 4.2? If so where does it fit. Again a pic would be good.
Is that it, or is there more to consider? Does it all need to be done at once? Apart from the pollution are there any other downsides to doing this modification? (Legality aside - we are of course talking off road use).
Thanks people.
4.Have also read somewhere there is also ‘something to do underneath the car’ ???
