EGR

hi,

In need of some help again.

I've blanked off were the EGR valve goes.
I now need to either blank the hole on the exhaust side or inlet side.

Does anyone know what the thread size is on the inlet side and if you can buy a grub screw to fit this.

Thanks in advance.

I don't know the answer, but the EGR may relieve crankcase pressure so you may need to think about some kind of valve and catch tank setup. I did this on my Pinto although it never spat any oil out in practice.

Spooky - been playing with EGR delete myself today (1.25 Zetec se).

Did you use a blanking plate, and if so, what did you use for the gasket?

Thanks

Hi there.

I've blocked the breather on the inlet side of my duratec and it breaths from the cam cover, using a wet sump at present, but I have a dry sump kit waiting to be fitted....

Cheers

Ian

I think we have some confusion between Exhaust gas recirculating and crank case breathers
EGR is a closed system allowing exhaust gas to be reburned a second time via a valve and cooling system
Crank case pressure is relieved via a valve into the inlet, if the valve is removed then it can be piped into the catch tank, I wouldn't just block it off and hope the presume bleeds up to the rocker cover via the oil returns although you can feed the block via a pipe to the rocket over and then via another rocker pipe to a catch tank

My exhaust manifold blanks that side and my inlet manifold was made to cover the other side

You don't need to blank the inlet side I did it to look pretty.


You will also need the blanking plate for the back of the head.

Hi,
Just to clear things up as I do think some people have got confused. I am only talking about the EGR valve. I have put a blank on the back of the head were the egr valve would normally go. I was just seeing how people got over the problem with regards to cover/blanking either the exhaust side or the inlet side.

My inlet manifold does not cover this hole but I may just make another blank plate up to sort this out.
I was hoping someone had found the thread size so I could blank it with a bolt

Point is you don't need to, and when it's in the car fully assembled you will not see it

There is a cut out in the cylinder head allowing the exhaust gases from cylinder 4 to pass through to the inlet side.
So if I don't blank it off either side then when the engine is running exhaust gases will escape out of the inlet side.

The design of the original exhaust manifold has a concave profile which allows gasses from all cylinders into the groove not just no 4

Your new exhaust manifold which should be flat can extend over the groove to blank it see pic below, depending on the design of the exhaust manifold it can be left open.

I believe I owe big- vee twin an apology as he is correct when he said as long as the egr valve is blanked off the no gas can pass through to the inlet side.

As I've already made a plate up for the inlet side I shall use it just to cover the hole.

Cheers everybody for your input.
