Egr Blanking Mod

On the TD4 all you need to do is stop the EGR valve from opening by disconnecting the small vacuum pipe, presume the Discovery is the same just make sure you block the vac pipe. You can try blocking the exhaust inlet pipe but whatever you use needs to be substantial, not like some really cheap EGR bypasses.

Just a thought.I cant undo the 2 allen bolts on my 1999 Disco 2 that hold the EGR onto the manifold,Although i have a full set of allen keys metric and imperial i cant seem to get one tight enough in the allen bolt head.So can you leave the metal EGR pipe fitted to the manifold as stock and blank of the other end of the pipe ? Just a another thought.( Evan thought of hack sawing the metal pipe off and squashing the end and put a bit of weld on the joint )Yea i know its a bodge but when i have put the closest fitting allen key in the bolt heads and applied pressure i know that either the key will slip then round off or the bolts will prob snap.

At a guess you tools are made from toffee!

You'll be pleased to know that your labours will have been in vain as the next time you remove the inter cooler pipes they will still be full of oil, just seems to be the system. If anyone can prove me wrong please do as I would like to get rid of all the oil in my intake system.

Hi Nick, to get rid of all the oil in your intake system is an easy job, just block off the cyclone (or for the older ones tampax model) outlet and that's it. Don't know whether that should be such a good idea though.:D
 
Allen 666,
Are you using the 5-star security keys and not the normal 6-star ones ???
My egr was fixed with 5-star bolts and such keys are hard to find so I cut a groove in the head and use a flat screwdriver.

Thanks Willo, after seeing the results of a blocked filter on one of the previous threads don't think I'll bother:D

Hi Nick,

Co-incidentally I had reason to remove & replace the 90degree bend hose on my truck today - surprisingly little oil - just a trace - and definitely not the messy black gunge that used to lurk around there.

A wipe with a paper towel was all it needed.

I didn't really need to remove it completely - but thought I'd just have a look inside. My problem is that the hose moves a little after a month or two and I need to re-position it so it will not eventually slip off or leak. Even 'T'-Bolt hasn't stopped it.

Permanent solution of course is a bend with arms a cm or two longer. ;)

Singvogel. :cool:
 
Thanks Willow,I never realized that there were 5 or 6 star allen keys.I do use the Torx bits on my Harley,I will check it out,I nearly always buy tools that are not nesaary the most expensive but mid way in price.Any way thanks Im now having a look in the machine mart book for 5 star allen keys.

Be careful there are many types. I have both 5 and 6 star torx bits.

I bought the 'security' torx bits (they have a hole in the centre to fit the little pin sticking up) as they fit the 'non-security' screw-heads too.

I first needed them to change the MAF.

Thanks George,I will get a set of those..The main laser importers are only about 20 miles from here in Southam.I have to go out there to see some one so i will call in and see them.
 
How wet can the plastic manifold get when cleaning as in image 3 of the original post?

As there is an electrical connection, I am a little concerned.

Hopefully, weather allowing, I will also be doing mine tomorrow, complete with the turbo filter and oil vortex thingy.

My 1995 300 tdi has the small (about 3/4 inch)breather hose connected to the large engine air hose between the air filter box and the turbo inlet so the crankcase/rocker cover has the air sucked out.

I want to stop the oily air being sucked into the turbo.

If I take the breather hose off the large hose, do I need to connect it to a waste can or an air filter of some sort?
 
I have started the job and am as far as about to change the 'oil vortex' or whatever it is called.

Is it just a matter of taking the old filter out and dropping this new bmw part in?

Not stripped that part down yet.

The manifold is soaking in mr muscle oven cleaner.

Might be better if you asked in the Discovery section, you may end up with the crankcase pressurising if you let the hose vent to atmosphere.
 
I just tried to insert the BMW oil vortex and found that the small cut out is in the wrong place so it won't slide in.

Looks like I will have to cut a small notch out to allow it to sit in its place.

Any reason why I should not do this?

:violent::violent::violent:




I can't think of a reason not to do it.

Should I make sure I seal the original cut out?

Its not as if it will be airtight.
