🔧 Spectre Performance PCV Breather with 42845 O-Ring Review

After I put it to the test on my automotive project, I was supremely disappointed by the lacklustre performance of this emission system accessory. While it supposedly helps with engine ventilation, it ultimately did more harm than good. The only upside was the ease of installation, but that's hardly worth the price tag when it doesn't do the job.

The only problem I had was the rubber accent rings. They don't last very long before they start cracking and then soon break and fall off. Other than that, it's a quality item. Chrome is good and decorates the engine.

I was surprised to learn that this is a self-contained breather. Most respirators have an internal filter. Contacted Specter Performance and they said it was standalone. There must indeed be a filter of some sort. I build several hot rods a year, this is my first time using Specter parts. The vehicle has only driven 30 miles since this product was installed. Drains bad oil. Cheap O-rings don't last. Cheap construction etc. There had to be an internal filter to fix the oil leak problem…
