Well, as the title says, my curiosity is raised over the viability of the EGR bypass over the benefit of using an oil catch can. This is on the M57N single turbo in the E53.



My EGR has caused many of the previous engine issues I have had and it is only now that I am learning what a mongrel idea it is.
To put perspective on why mention catch can, my younger brother who has had many diesel off road vehicles and his son as well, have had some similar issues. The EGR was the root cause of the problem, even on my nephews brand new Isuzu IMax.


They have fitted oil catch cans on all diesels after having an issue and then they no longer have EGR problems. The other point he mentioned was the amount of condensation that was also trapped and not fed through the motor. Whilst not a large amount, moisture is not something you want running in with your lubrication.


Has anybody here on the Forums who own diesel X5's fitted one of these to their vehicle? What are your response and views on the subject?


Something else I have given thought to, is a turbo boost gauge...Has anyone ever fitted one and if so how is it hooked up?


Looking forward to hearing from you all, especially the M57 powered owners.
Jeff
