could anyone tell me what the egr blocker plate is and what they do

The EGR is a smog device that recycles some of the vehicle exhaust into the air intake. This puts additional soot into the engine which is believed to shorten the engine life. Some guys put the EGR blocker plate in front of the EGR cooler to prevent any recycled exhaust from being used in the intake. Some guys notice an increase in mileage and some dont. For about $20 I dont think it will hurt to get one, but for me Im just going to change my oil every 5000 miles to get the soot out. There are also by pass oil filter systems that remove very small particles of soot if that is what you are worried about.

thanks for the info

I havent done it yet. Plate is still in my center console....but there is some threads on this and its a pain in the butt. Do a search and lil reading you`ll find the easiest ways to put it in.

Mine is sitting at work...looks like a pain to put in. But one day I will.

x2. i have had mine for 3 months

Pardon some related EGR questions, but is it true that:

just unplugging the EGR connector from the wiring harness will eliminate 90% of vapor flow? ...
(because then it will only bypass some crankcase vapors when the turbo boost gets high);
and so, the pain and effort of that blocker plate is now only for the 10% condition?
and further regarding sooty oil;
that the new Amsoil EaO full-flow filters perform most of the role of a bypass filter? ...
effectively 'bypassing' all the cost, maintenance & installation effort of a bypass filter?
IF SO ...
==> then a simple wiring disconnect cures 90% of the "sooty oil" problem
==> and the remaining 10% can be managed with a spin-on filter.
Lemme see here .... :rolleyes:

Not even close.

Hows that 110 with a DPF? :rolleyes:

I was planning on putting a blocker plate on my truck until a friend of mine, who is a diesel mechanic, showed me a twisted piece of metal about 1 1/2 " by 1 ". He said it was a piece from a blocker plate that had gone through the turbo.

I guess that the moral to the story is that if you do put in a blocker plate, make sure that it is fabricated from a material that is appropriate to the application.

Most of been a POS homemade blocker plate.

If you unplug the egr you won't really know what position it is in when you unplug it. Also, at higher boost levels, the egr can still be blown open. I dunno about those amsoil filters, but the sooty oil is a mix of the exhaust from the egr being brought in from the egr and the from the oil coming in through the pcv.
