Uh, well, YE$
How's this for bright.
Loyal user of 76 Royal Triton QLT semi synth oil, I (was) getting a great price on the stuff. I knew I could run it longer than 3750, oil analysis said so. So I got to thinking, a bypass filter will make it even better. So I went with an OilGuard EPS20.
After letting it sit for months while I contemplate mounting, routing plumbing, etc, I started the install.
Mounted up the assembly.
tapped into the test port on the filter head for supply and decided, slick would be running the return line into the vacant oil dipstick tube boss on the passenger side of the engine, remove a freeze plug, carefully tap the whole and done right?
Uh, more like TAPPED that freeze plug into the oil pan trying to remove it!
Three hours of trying before writing it off as having to go to the dealership.
Needless to say, I'll have to put some 200,000 miles of extended intervals on the truck to break even for what it cost me to get that pan dropped to rescue that plug.
That was a $tupid and Co$tly mistake.

The others, well, no witnesses to a lot of them, so they're best left not shared.
