All DI's have this to certain extents, but here is what we need someone to do. Anyone handy enough to remove your intake manifold (not hard, just take your time and it takes minimal tools). Remove your intake manifold, and then you have a clear shot into the intake port to see the valves directly on your engine. Please take pictures to post and note how many miles you have on it. The EB works as all DI engines do but there are different valve timing and injector timing events that the different manufacturers are experimenting with. So far we see some with less rapid build up so we know there is some headway being made, but none are immune. Also, in some of the articles out there (look for real SAE white papers,e tc. but most are taken from the actual ones as what is posted in the above threads is dead on accurate) you will see some have voided warranties by installing breathered cans that open the system, and that you never want. It must be a system that retains emissions compliant function.
Now, PaiterPat just left. What we found is the drill location for the front intake tube is before the fresh side barb, so at cruise it has been over powering the flow not allowing the can to work properly. So, everyone please note, no need to drill the front inlet pipe. Simply use the 5/8" barb to T into the back side one and then use a 90* 1/4 NPT x 3/8" barb for your clean side hose connection and drill it just after (down from) the air filter/air box. and connect the cleanside separator their. We tested and it worked properly, and it makes install easier. The trucks we can reach to drill downstream so that has never been an issue. Whichever fitting is closest to the turbo will over power the one up stream even if only by a few inches. So, he is checking back in 500-800 miles to see the accumulation at that time. Any questions, or anyone needing a fitting let us know and we will get it right out.
You want the fitting installed for the cleanside separator as close to the air filter as possible.
