ECG Blocking plate

[madchef]

Hi All
I got a small question about blocking my EGR , I think it done but ?? I have a zd30 2007 engine, and the pipe that goes from the manifold to the other side of the engine around the back has a small crack on the manifold side on the weld of the pipe, I have tried to seal it but the putty keeps blowing off, can I put a blocking plate on the manifold side is my question ?? so it don't blow out, if not ill take it of and weld it or buy a new one, Hope you all can help.

Thanks

Dave

Sorry EGR. Plate lol

[threedogs]

once blocked there should be no gas entering the egr pipe, could be wrong

Those pipes going round the back, always split ... They screech and carry on under boost. Need to be replaced or removed and capped both ends.

Yeah, blocking the egr pipe on both ends with plates is an easier, cheaper solution than replacing the cracked pipe or trying to weld it.
I blocked the exhaust side of the pipe(pipe was cracked) with a right size bolt from Pirtek & inlet manifold side with a home made blocking plate made out a piece of tin.
(I removed the EGR pipe, valve and the rest of the EGR pieces. Mine's an RB30)

Thanks guys, I will block the manifold end also as it keeps blowing the pipe weld off lol, will get some stainless and fit it between the manifold and pipe, Then next job is small gasket on oil pipe on turbo as I got a small oil leak not dripping just a little dribble.

Thanks

Do you think your EGR blocking plate is still there being made from tin.
Thinking Stainless would be a better choice, just saying lol

I think I will use thin stainless , I got a small piece someplace .

It is still there. I put generous amount of gasket sealant in between.
It's basically blocking plate for the inlet manifold.
I didn't think it needed a thick stainless steel one.

On second thought, I should check it tomorrow. It's been there for quite a few years now(since 2012).

Dunno whether it has to be stainless. Thicker plate is preferred, but normal steel or aluminium plate should do for the intake manifold end.
Exhaust end, in my case, didn''t need a plate. I just blocked the threaded hole on the exhaust manifold with a matching bolt. Pretty simple job.
Then I removed bits and pieces of EGR assembly. There was a vacuum line that went to EGR valve from TVV(thermal vacuum valve), which I simply blocked with a bolt screwed into the vacuum hose. TVV in RB30 is basically there for EGR(It's on the coolant line where it joins the cylinder head). I recently blocked the vacuum lines go to TVV as well, 'cos it doesn't serve any purpose without EGR.

If the exhaust end EGR blocking has to be plate, then a steel or stainless steel plate is probably better than aluminium one.

Well I first blocked the one on the manifold . Then it was still blowing through the crack from the other side, so we blocked the other end of pipe, all good and no problems, so do I have to block anything else off ?? So basically the pipe is now void .. And I used stainless . Easy job but had to sit on engine and on my stomach lol bolts were bloody tight.

Yeah, the exhaust side bolts are bloody hard to remove with years of rust and heat, and basically end up being welded to the exhaust manifold.
I had to use a pipe wrench to remove the broken part of the exhaust side pipe from the exhaust manifold.

Check for any vacuum hoses that go into the EGR valve and block them accordingly, 'cos the EGR serves no purpose once both ends of the EGR pipes are blocked.
