Like an archaeologist digging through layers of sediment and finding signs of earlier civilizations, I’ve discovered several locations on my bike that have had previous work done. Example: The oil filter bolt.

I presume the bolt was stripped and the previous owner used a cutting disc or angle grinder to fashion some sort of primitive rectangular knob to be able to turn it and get it out. What I can’t understand is why the bolt was put back in. A new bolt can easily be purchased for around $10 bucks.

I used some vice grips to try turn the bolt… after a short battle, I was the victor. It came loose and I drained the thick, dirty, black oil.

• I wiped down the oil filter housing
• Installed a new oil filter
• New rubber gasket
• New shiny oil filter bolt
• Poured in a few quarts of fresh SAE 10W-40
