Quick oil change question. - 986 Forum - The Community for Porsche Boxster & Cayman Owners

Im looking to change my oil shortly. I have the oil filter and o ring for the filter. Does the drain plug crush ring need to be changed? If so does anyone on this board have a extra one they would sell?

FWIW... I've used new washers only if they were supplied with the filter. Most of the time I've reused the washers. However, I paint a thin layer of fingernail polish (the wife's old stuff) on the drain plug's threads as a sealent. Just tighten the plug to the proper torque - no drips, no weeps. It is not that I am cheap; it is just convenient.

The crush washer is readily available at the dealer, if I remember correctly something like $0.50 to $1. When I bought with the oil filters on-line it was ~$0.25.

What's the best color?

Whatever she no longer uses. Let's see... Base Coat, Platinum, Rosetta Rumba (those go on the drain plug so no one can see them), and Denim Chrome (which is also a good match for the blue on the license plates.

I like the sound of "Rosetta Rumba". I'll see if I can pick some up for my wife. Maybe she won't like it and I'll get to use it !

Seriously, finger nails polish really works as a sealant?

Definitely buy some for your wife - also some jewelry. Then she'll not be too unhappy when you buy some goodies for your "S".

I've used nail polish for about 20 years both as a sealent and as a "LokTite". Just remember to insert the drain plug while the polish is still wet.

Replace it. The old one has conformed to the bolt wherever it stopped and the pan. That makes knicks and cuts in the aluminum crush washer and bends it to fit snug against the pan. If you use the old one, the knicks, cuts and bends don't match up and can allow leaks. It's cheap $.50 insurance against oil leaks.
