Blocking the EGR Valve

[fracster]

Ok, I have a blank on order for my 2.8 and will remove the butterfly. Question is, where and why do I need to fit a catch can please?

Sussed it, should have used the search function more thoroughly.

I've seen where people have asked whether to block the EGR at the exhaust or the inlet. Why worry. I just took my entire system out. Block a few hoses. Throw the plumbing away.

The inlet side is blocked with a self made plate (contemplating measuring boost at that point - any comments).

The exhaust side is where I installed my pyrometer sensor. It's more accurate here than on the down pipe.

I know it some states this might be considered a bit radical but with the plastic cover on who can see? And if you get tested you're going to have issues regardless.

I have used it with and without the valve hooked into the ECU. Seems to make no difference although it is hooked up now.

300K+ on the ZD30.

I think the biggest advantage to blocking the EGR is the cleanliness of the engine oil. Before blocking the oil was black even immediately after an oil change. Since blocking it is a lot cleaner.

Great info, sure to carry out this mod while rebuilding the engine

Well after 13 years of owning my 2.8 GU. I finally had the courage to block the EGR, remove the butterfly valve, and disconnected the charge air temperature sensor. The car is now performing much better

Here ya go mate.

Is it crucial that the td42 EGR is blocked on the manifold side or can it be blocked underneath where the pipe fits on? My plate fits both.

Either is OK.
