Review on 🔧 SMART-O R9 Oil Drain Plug 1/2 - Smart Features & Benefits, High-Performance Sealing Technology, Patented Anti-Leak & Anti-Vibration Mechanism by John Clarey

I rebuilt a '64 Shelby Cobra from a company called Factory Five. I put a Ford Racing Crate Engine (5.0 Coyote) in it and had to use Moroso's flat all-aluminum oil pan. From the start flowed out from under the oil plug. Nothing I did would stop him. I've tried new plugs, tightened, loosened, tape, sealant, sealing washers and the leak kept coming back. I was afraid that I would have to remove and change the palette. I came across this product and completely fixed the leak for less than $10 and it hasn't come back. Also, with this design, you don't have to tighten the connector as much and it doesn't vibrate. Picked up the races, no leaks even with such ridicule. What an ingenious yet simple idea. I will put them in every one of my cars including my Daily Driver cars when I complete my next oil change. Seriously if you have a cork leak don't look for anything else and just order it. HIGHLY RECOMMENDED!
