Am conducting a little experiment.
Just finished engine rebuild on my TR3. Tried to start it, discovered I was a
tooth off with the ignition, fixed that, and then it started right up. Ran
smooth and strong with no leaks for 25 minutes before I shut it down. Made
some water pump noise for a few minutes, then that quieted right out. Smokes
more than I remember from last time, but I expect that will sort out as the
rings set.
The experiment is, I added a few wads of magnets to the outside of the sump,
near the magnetic drain plug, to see if it doesn't capture more metal shavings
common with rebuilds. I don't see why it wouldn't complement the already
magnetic plug.
But it raised the question. While I know the zinc in the Valvoline Racing Oil
I'm running for break-in is not magnetic. ...But...are there other elements in
the oil that would be sucked from the chemical composition by a strong magnetic
field?
