Piston Slap: It's Not You, Drain Plug…it's Me?

Dear Sajeev,

I have terrible luck with oil drain plugs. Of the last 4 oil changes I’ve done, only one has been successfully completed in a single day, because I can never get the drain plug loose.

The culprits in these comedies of errors are a 1999 Saab 9-3 and a 2006 Honda Pilot. The first time I came across the stuck plugs, the Saab was a recent acquisition, and the Pilot had had its last oil change done at a local mechanic’s shop down the road. Therefore, I assumed that an overzealous shop jock who got trigger happy with an air gun was to blame. In the process of getting the plugs out, I managed to mangle the Saab’s bad enough to require the purchase of a new one, and should have also bought a new plug for the Pilot, too (but didn’t). When I reinstalled them, I put them in fairly snugly, but with the mindset that I didn’t want to get myself into this mess again.

Still needs an exhaust manifold gasket. The front end got serviced in year 28. On the plus side blank cassettes are increasingly easy to find so I have a solid collection of 90 minute playlists.
