Crush Washer

[tama48]

Which way does the crush washer go on the oil pan drain bolt? I can't really tell by looking at the old smashed one. Like a bowl with rim against pan or like a bowl with rim against inside head of oil pan bolt?

Thanks

I'd assume the best way is with the more flat or concave side goes against the bolt shoulder. The rounded or convex side goes against the oil pan surface. If you put it on the other way, I still doubt it would leak. I've changed oil 4 or 5 times bofore without ever changing the crush washer... and never had a leak. I typically change it every other time. Just be sure not to over torque it. 25-30ft-lbs is plenty.

The rim goes against the pan.

Thank you. That's the way I did it.
