Technical EGR Blanking on JTD

Ok Kev, I'll leave the guy some positive feedback.

Are you still making 8v blanking and 8v restrictor versions?

If you are will you be making 16v blanking and restrictor versions?

Just PM'd you my address. How many are you planing on making and sending to me, do you want me to help with the delivery costs?

Hi all,
Sorry been away from my PC.
Yes if you can trace round the end of an EGR that will be perfect. I guess the best thing to do is make one send it to you to "offer" it up and if all is ok i can whack a few off.
Stu i was thinking about making what 15 of each ? and yes i got your PM and no i will post them down to you no probs.

Cheers for now
 
I also used a can of Wynns EGR cleaner, which literally washed the carbon off. The added benefit of the Wynns is that its designed to be sprayed into the intake system whilst the engine is still cold and hence is circulated through the EGR. Assume regular use will prevent excessive build up.

Anyone tried this? I'm not particularly good at nuts an bolts, but I can spray a can! If you sprayed, where? Remove the MAF and spray through the hole? I don't have any performance issues, and I get mid-high 40's MPG, so I'm assuming that my EGR isn't significantly dirty or blocked...

Personally I can't see how it would clean the EGR if it was sprayed into the air intake. Once it reaches the intake manifold it would have to travel against the flow of exhaust gases entering the intake manifold to get to the EGR. Disconnecting the flexy hose on the side of the EGR and spraying it into the EGR would work because the engine would suck it through the EGR into the intake manifold.

It may clean the intake but it aint cleaning the EGR, waste of money IMO.
 

It is sprayed into the engine -after the MAF- with the revs held above the EGR opening threshold - 2500rpm.

The reasoning being that it goes through the engine by normal induction and then is recycled through the EGR thus cleaning it.

It does work to a limited extent but of course the EGR has to be operational not clogged solid and it does not beat removing EGR and cleaning or better yet blanking off same completely.

I thought EGR was some warm up device to keep cold start emissions down that's why they soot up so much?

Got the fiat run down from my tech friend, they open twice as soon as you turn the key to check them selves, them open/close all the way through the rev range constantly depending on the readings. :D
 
would blanking off the egr valve throw up error codes?
right now i keep getting check engine light (usally when cold) and the turbo won't work till warm, the wastegate moves easily, i cleaned the map sensor (the small black unit plugged into the inlet manifold. so i guess all is left is the egr valve or maybe o2 sensor... i have a odb2 reader coming.
 
Most 8 valve JTDs record a fault code, but no warning is shown on the dashboard. If you have a Lambda (O2) sensor, then you don't have an 8 valve engine.

16 valve JTDs record a fault code and show a dashboard warning (MIL)

The JTD engine doesn't have a wastegate, it has a variable geometry turbo (VGT). The diaphragm chamber on the turbo is to adjust the vanes in the turbo.
 
ok cool, it looks like a twin cam head and there is defiantly an o2 sensor right at the top of the exhaust manifold. would a sticking EGR vavle cause the turbo to pretty much stop functioning then possibly heating it is freeing it causing semi normal function?

If the EGR valve is stuck open there's a very good chance it would cause a serious loss of boost by allowing it to escape into the exhaust system ..
 
I've blanked of my EGR, and went to MOT. We do it once a year in Croatia. Honestly, I forgot to un-blank the EGR, but the eco-test (exhaust gas test) was normal, and fully green! How's that?
