CT4-V Dirty valves !!

[Aaron4BW]

As expected, DI shows its weakness. This is at 6500 miles (LF4). Time to fab up an oil catch can because I can't find any plug & plays for us just yet....
On a side note, anyone have a link, or can point me in the direction to a walnut blast/vaccum intake manifold attachment for the LF4?? I'll probably give it a good blast every 15k or so now.

I saw a guy on Instagram with one.

That is just unacceptable on a car with just 6500 miles

Curious what Tapout has to say. I've seen tons of High Mile ATSVs out there. Not all of them can possibly have catch cans.

This is fairly normal for direct injected cars. However, this doesn't seem to cause any measurable degradation in performance.

So....CT4-V B.W.'s don't need a catch can? Obviously Cadillac doesn't think so? Tapout what do you think?

We are not running aftermarket catch cans on any of our or customer's CT4-V Blackwings. And we have several of them in the 700 whp range now.
