Overall Assessment

Customers highly appreciate the product for its superior quality, suitability, and aesthetic appeal. The PCV housing, in particular, has been well received for its sturdy built, and users recommend investing in the rubber grommet for the best fit. The breather and PCV are not an exact match, but both are acknowledged for their fine quality. Some users reported missing screws in one breather, yet their overall feedback remained positive. The product adds value by complimenting and matching other components, like valve covers, perfectly. Its excellent, show-quality finish is also highly regarded, with some confirming it as worthy of repurchase.

Questions & Answers

6 Questions • 6 Answers

Newbie questions: Do I use 91017116 on one side, and this on the opposite? Should the hose run from this to the carb base/ intake to get flow through the engine, or should I run the hose to a catch tank? Do I connect 91017116 to the air cleaner, or is it a filter inside it? I have a set of finned valve covers with no holes. Can I just drill holes in them and use the grommets, or do I need different valve covers?

Can you put a PVC valve in this? 307 with edelbrock manifold and carb in a 1957 chev. Right now I have a breather in the pass side and a PVC valve on the drivers. Can I eliminate the PVC or can I put one inside this breather? I would like to get the finned breather and the finned PVC breather to have the same look on both sides

can this breather be used with a evacuation system? I have a system that has a breather hooked up to a 5/8 hose running to my exhaust system. I want to purchase your tall finned valve covers and use this as my breather.
