3. Would a catch can alone prevent build up, since oil would no longer be introduced into the intake stream, creating havoc mixing with the EGR.
Nonetheless, there is light at the end of the tunnel for the 335d in the US market.

1. so long as you arent subject to random emissions testing, its entirely within the possibilities to run a block off, remove it a week or two before testing, reset the DDE and allow it time to reset the monitors before testing. I fully intend to smog my car when the smog renewal is up.
2. that is a good question, i cant really answer that since I didnt check the manifold in the time I had meth on but not EGR block
3. another good question which I cant really answer. I dont think there is much question though that a catch can would help and maybe a really effective catch can would stop the build up.

whether you choose to believe it is an issue or not is up to you, but there are large numbers of US 335ds ending up in dealerships for this very reason. I wouldnt mind if you posted a picture of your own runners so that we can check and compare
Ive never seen a diesel tractor that revs to 5000 RPM, and if I have the choice between clean room intake runners and gunked up intake runners im going to take clean room every time.

The "before" was before meth or EGR block

all of the EGR delete cooler cracking seems to be on much more modified cars and also from what I can tell seems to be on cars which have EGR tuned out and not blocked off. I dont know that the tune vs block has anything to do with anything or if its even true since I dont think many people are using a physical block instead of a tune.

mine is after the EGR cooler, right at the EGR valve. TDIwyse I believe has a bit different setup he is running with the EGR deleted (block before the EGR cooler)
