Thanks for the great response on the issue of a cartridge versus spin on oil
filter. We did the cartridge route for our first oil change and expect
Santa to drop off a spin on adapter.
But, the oil plug was another issue. Go kart racing sold us on magnetic oil
plugs (makes a huge difference when you don't have a filter), so we had one
ready to put in during the oil change. First problem was getting the old
plug out. 3/8 and 11MM were not really the right size wrenches. Adjustable
wrench (I thought last resort) wouldn't grip it. You guessed it, vise grips
to get the drain plug out. A conservative guess would be about 60 ft lbs of
torque on the plug. The plug appeared to be a tapered 1/4" (guess) pipe
thread plug. The magnetic plug we had ready to put back in (nice face with
a copper crush washer) wouldn't even go in those threads. So we put the
pipe plug back in.
Anybody else run into something like this? Any idea what those threads
really are?
