    EGR Blocking plate

    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

    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

    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.
