REALIZATION: Almost every aftermarket modification requires its own maintenance that the lesser OEM part did not. This is reality that I’ve experienced over time and I finally decided to write something up about it. Here’s an example.
My Hyperflow oil catch can (PDF file) needed emptying again last week after another 3 months in service. When I started to remove the five tiny button-head screws on the cap to drain it, I stripped one of the hexes. I put the other 4 back in place and reinstalled the can with plans to revisit it when I found out exactly what size the screws were so I could buy some.
LESSON: Tiny machine screws holding the top on a catch can do not need anything other than snug tightness.
After 3 days of deafening silence from the “sales” contact email address for Hyperflow as well their primary US distributor, XX Tuning in CT, I decided to email the “R&D” contact email address. Lucky for me, Blake at Hyperflow replied and indicated that the screws were M3 x 6 with .50 pitch. He also offered to drop some in the mail for me if I lived in Australia.
Having failed to find anything smaller than M4 at my local hardware store, I dipped into McMaster-Carr’s vast product archives and found exactly what I needed… in boxes of 100 pieces only. Oh well, 100 it is. Nine bucks and a few days later, I had them in hand.
On my day off today, I tackled the catch can again.
When I took the cap off via the 5 screws and went to remove the internal foam filter, it completely disintegrated. It was fine 3 months ago. Luckily I had some fuel cell foam handy (who doesn’t? …) and shaped a new piece to use.
Take some of my advice the next time you’re itching to make improvements to your ride: Think about it with a clear head and understand the future maintenance requirements. ∞
