Egr - ka24e

[lfteixeira]

Hello.

It's time to remove or install a blank plate on the EGR.

I can't find specific information about the procedure, can any body shed some light?

How easy is to remove the EGR?
Where can i find a blanking plate, or is better to make one?

Remember, 2.4 petrol, KA24E.

Thanks.

Have a look at this.

These valves on the 2.4 stick open, I can tell you where to drill a hole in the top casing and then use a drift to close the valve, as long as you have disabled the vac to the valve it should be fine and a lot easier than putting a blank plate in, Rick

new mot rules if fitted should be there.lots of peps took egr off now trying to find to put back on.

Here we don't have that kind of problems, for now...

Nice video, but that is on the diesel engine. They are different, aren't they?

Yes they are, but look at my last post, Rick

Yes please, enlighten me!


Some photos of mine with my very technical terms:
* The A thing has 3 vac hoses, 2 on top and 1 on the bottom (C).
* The B hose connects to the C thing.
* The C thing have 2 vac hoses. The B and D.
* The C thing is connected to the EGR, right?

(This sound like a math problem! )

C is the EGR valve the rest are unimportant, great pics by the way, tomorrow I will take pics of exactly where you need to drill and how to disable the vac side of things, as for MOT the EGR cannot be tested unless the test is conducted on a rolling road under load conditions, Rick

This is the valve with the position of the hole, it does not need to be as big as this, half this size will be fine but try to get it in the middle of the circular recess, be careful on break through, if you go too deep say more than 20mm with a rotating drill you risk damaging the top plate of the rubber diaphragm disk, next insert a drift and try and push the valve down (you will be directly over the top of the pin that pushes the valve down) if it moves at all then it was jammed open, quite common) next hit the drift a couple of times moderately hard, this will seat the valve, all the valves I have come across were passing and this stops that happening, now you need a couple of ball bearings or similar, these go in pipes D & B, D is open to the exhaust & B stops the vacuum operating the diaphragm, which it cannot now anyway as you have a hole in the top, but it will waste vacuum, also it would be a good idea to put a nice blob of high modulus silicone mastic over the hole, this will allow you to undo your mod at any time in the future, Rick

Rick, fantastic explanation. Thank you.

I will remove the EGR and do the procedure... Wish me luck!

If you are going to remove it you might as well put a blanking plate in there, you do not need to do anything else, Rick

Humm...

it doesn't seems to have space to use the drill directly on top without remove some stuff from the top.

I will check that in a bit!

Hello.

I can't fit the drill in the space to do the hole in the correct place.
Removed the 2 bolts and inserted a piece of cardboard to make a template.
The pipe that goes into the exhaust won't move, so i let the EGR in place.

Today, before work, i created a plate from 2mm steel.

Let's see if it fits correctly.

Perfect, Rick
