Just got a walnut blast done, will adding an oil catch can prevent buildup at all?

Simple question, walnut blast is recommended every 50k ... if I install a catch can, will that slow buildup in anyway?
Meaning is there any way at all that 70k with a catch can would like like 50k without a catch can for example? |

Only if you run dual catch cans and plug the head.
Look at BMS for high side and mishimoto / rb turbo external pcv for low side.

I was planning on mishimoto, and then I’ve heard about the RB PCV valve, so how do they actually run together? How does the flow actually change? Does the RB valve not allow oil down a certain path? And then the catch can contains the flow? |

build up in inevitable with a DI only engine. It will just delay it a bit.

Definitely get the rb style pcv valve.
You may be better off just using the money you'd spend on a catch can for another walnut blast - doesn't catch much.

You really need to do the rb modification which includes removing the valve cover and tapping some holes. If you aren't comfortable doing this then I wouldn't bother with catch cans.

I have a burger catch can and an RB pcv valve. I pulled my intake off last week after a year since and its just as clean now as it was right after it was cleaned. I always have tons of oil in my catch can, but none in my intake anymore.

I have no say on the valves yet but would imagine they still get some build up without the head ports being plugged. |

If you don't mind me asking how much did your walnut blast cost you ?

I plan on doing another walnut blasting this spring. I will post pictures etc., of the intake valves prior to cleaning them. |
