I think the conclusion is - block it off, so it looks like it's there for Mr MOT Man, but it isn't actually doing anything, plus this is also the quickest and cheapest option

yes i guess, im going to replace mine soon too but with a aftermarket one and im going to just keep the old one in the shed just in case .the other option is to get the blanker remove manifold and take of the dreaded pipe that comes off it i see there is a nut screwed on the the e/manifold that holds the pipe iv oftern wonderd if this can be blanked /take off to or just get the other manifold .....ah but the expence and time can't be botherd..

Why on earth would you pay daft money for something that gives you no benifit that using a penny does not give you. Forget the boost in performance unrestricted air flow is claimed to give, it's bull****.

If you really want do eliminate the EGR, get a pre EGR inlet manifold from a scrapper and fit that, you can then remove the vacuum pump from the front of the cam and get even more power

I'm with you Wammers - I wasn't about to pay for something that I can either make my self or isn't needed!

I'm not after power, I'm not 17! I've had so many problems with EGR valves in the past that this is more like preventive maintenance

as for tuning tips - the best tip for the P38 Diesel would be ........
Forget it!!! start with something else!!

That was not a tuning tip, it was sarcasm. However quite a few have done the complete mod out here with manifold, pump removal etc, it can be got through the test as it then does not appear the the EGR was ever fitted. Quite why the test centers cannot check on this I do not know.

call me lazy but - too much effort finding all the bits, I'm blocking off and leaving it as that

I'm not but as for buying the after market one I figure if I take of my egr,the diagpham however spelt would still be good if ever I needed it,where as to leave it on it would wear down with heat gunge usage ect ect

If you block the exhaust feed to it with a penny no gunge as you call it will get into the EGR valve. If you want to preserve the diaphragm just cut the vac pipe to it and connect it back up with a solid blocker.

True what about heat wammers as metal absorbs heat and it is surrounded by metal over time of coarse???

i allways remove egr valves on my diesels, more to do with engine life to stop sooty exhaust particles getting into engine oil.
another american invention interestingly the question was raised about engine damage but studys never done guess they thought enviroment was more important than engine life!
no real performance gain does help improve throttle response and turbo spool up time very very slightly more evident when done with other mods such as decat performance air filter and a turbo boost checked and adjusted back up to manufacturers figures (or a slight increase)

Probably not noticeable on the older 2.5 engines but I certainly noticed a difference once I bypassed my EGR
Slightly more torque and faster pickup
If the EGR is bypassed doesnt that mean the engine is being fed clean air instead of Exhaust filled air ?? So a cleaner combustion so surly that would make a difference to combustion ??
Thanks

Think you totally miss the point. Blocking the exhaust gas feed to the EGR valve will give you exactly the same effect. There is no need to fit an after market unit. It does no more than blocking the feed does. Other than cost a lot more.

I totally understand
I just thought that the EGR valve itself blocked a lot of air flow ? Maybe I'm wrong

Sorry cannot see your view on this at all. Leave it where it is it won't take any harm. Removing it and adding an expensive replacement won't do any more than a penny does.

As i said before air is being blown in by a bloody great turbo charger. The restriction caused by the EGR valve is neither here nor there. The air in the manifold is under constant pressure the engine can only inlet so much at any one time, it won't run out of air because of any restriction in the EGR valve i assure you. Not having the EGR valve on won't help high pressure air flow past the inlet valves. Anybody who tells you that engine induction air will be increased if you fit a unrestricted adaptor in place of the EGR valve body is talking through their arse. It's the hot exhaust gas you don't want, stopping that is what makes the difference.
