EGR plate/Blocker

[damian.thomas]

Hey guys

After reading the massive difference blocking the EGR makes i am 100% sold.
I have seen on ebay and other websites EGR blocking plates for other model cars but no GQ 2.8td. Its not that i cant make it i just work more or less 7 days and the rest of the time in renovating so have no time, if not ill just have to suck it up and make one.

Thats because your gq wont have an egr. They were introduced in the GU's.

this is from a 3ltr ZD30 though and not a RD28

Oh ok http://www.nissanpatrol.com.au/forums/images/imported/2016/05/120.jpg i have this in my car, so blocking it will have no improvement? I read elsewhere on the forum other people doing. If not i guess its one less thing to do.

Hey guys

I got around to making the blanking plate today but when i loosened the two nuts and moved the egr valve to put the plate in i seen that the gasket was stuffed.
I put the plate in anyway went for a drive to see if anything changed and i noticed in third and forth gear when i put my foot down it would rev up to 3000rmp but not pick up speed very quickly. I figured it was leaking from the egr valve because of the gasket, so i went to supercheap, autobahn and repco and nothing in the ways of gaskets for the egr valve.
The guy at repco suggested gasket paper so i got some when home tried it and still the same thing.... has this happened to anyone else before? Could it be something maybe? Or does it seem like it is leakingfrom the egr. Any help would be great.

Cant say for sure coz I drive a TD42, but if th RD28 is like the ZD30, then maybe the computer needs to relearn..... I think disconnecting the battery resets the computer.....

Hipefully some of the more knowledgeable members will chime in

Need more than shrooms mate

Thanks for the reply cluck but no luck. Does anyone know if exhaust gas was leaking from the egr it would cause my car to rev out under more pressure?

Id say its revving out more because its getting fresh air now rather than a mix of fresh and soot filled air.

Guessing it's an auto?
Di or crd?
Any gauges?
When blocking the egr you get a slight increase in turbo spool up, due to now 100% of exhaust gas going threw the turbo..
This sometimes causes limp mode, if the turbo spools up too quickly or its picked up no flow in the egr.. both can throw fault codes..

Try drilling a small 6mm hole in the blacking plate.
A smear or stag paste or gasket goo to make a new seal, disconnect battery with lights left on for a couple of hours to reset the ecu.

The 2.8's wont go into limp mode due to the EGR blocked. So drilling a hole will be pointless. But if it is leaking at the plate, check the surfaces to make sure they are flat, gasket goo as mentioned may help. The RD28 EGR valve is vacuum controlled, not electronic. So disconnecting the battery may be pointless. But its worth a shot.

And to add. The RD's have a pressure relief valve on the intake manifold, because you have blocked the EGR, boost pressures will be higher so all that extra pressure may just be going out the relief valve. I have heard of people removing this valve and blocking the port on the manifold. But you will also need to install a manual boost control valve then to control your boost pressure.
Having said that I feel this may be your issue.

Augh. Good pick up lol..
I gotta stop posting at 3am...

But good advice on the relief valve. A recent member had a faulty one and it was just by passing when on boost..
I'd say check what mark has suggested..
And a boost gauge and controller..

Yeah thats what reminded me. Was an overseas member i think.

Thank you for all the replys guys, got some copper gasket silicone today so i might pull it to pieces tonight and glue it up. Next will be a manual boost controller, gauge and egt if it doesnt work.
