Well a bit of an update.
After a few weeks of driving im pretty happy with the results. I did modify my catch can and made a baffle inside it. Its catching oil well now.
With the EGR blocked, new IC and IC fan I'm seeing lower EGTs - especially at highway speed.
I'm sticking with the standard exhaust, therefore im not going to install a dawes.
Ive been toying with fitting a snorkel. - I like the peace of mind for water crossings (not that i do that many), but I've hear a lot of horror stories about the CRDs using a lot more fuel once the snorkel is fitted.
I'm guessing the MAF gets a bit tricked and changes the fuel input?
Anyone else experience this?
Ive got 2 mates than have fitted snorkels to the CRD, and both went from about 11-12L/100 - to 15 to 18L/100
I'm not keen on that.
