I agree with all that Tom suggests for the dipstick fix.
However, I have found that the cleanest solution for plugging your original dipstick hole is to purchase a 3/8"
oil gallery plug (looks like a miniature freeze plug, and costs about .50 cents) and, using a dab of silicone around the edges, tap it in using the appropriate size drift. There is a slight ledge in the hole that the plug bottoms on, and prevents it from falling into the engine.
Have done several this way, all with positive results.
