2001 Honda Accord V6 Oil Leak at Pan Drain Bolt
I have a 2001 Honda Accod V6 that is leaking from the oil pan drain bolt. When the bolt is replaced, it is hard to turn without a wrench. However when it gets to the end of the bolt, it doesn't tighten and in fact gets more loose.
It is leaking a small pool of oil, perhaps 5" in diameter on a cloth/carpet area over about a 12 hour period. I have changed my oil before and it didn't leak this bad at all. I haven't had time to mess with it this morning because I had to head to work. I did check the oil and it didn't seem to be a significant drop. This car has 150k miles and I would like a "simple" fix. Perhaps a new bolt or other method that could seal it properly without more drastic measures? |
When you changed the oil did you use a new crush washer? If not then that is most likely the reason for your leak.

I did not. Does this explain why the bolt gets loose and won't tighten at the end?

Yes, You're supposed to get a new washer every time. ( I have to admit I only change it once every 2-3 oil change...) you can get them at any auto store...

FWIW, I cheat; I use an oil extractor and suck my used oil out from the dipstick; I haven't pulled an oil pan drain plug since 1999. :) |
The newer alum pans are more prone for thread damage. Yes, as others have stated , replace the washer every few changes.
Try a new one.......or two :eek:, I said that. Yes if one new one and you still have a leak, add a second and know the pan threads are on their last leg. There are several choices you can down IF and when the threads in the pan finally give out, |
Did you ever get the leak fixed? If the bolt isn't engaging correctly you've most likely stripped it and the washer isn't the culprit. However at about a buck each you should replace the washer every change. If stripped and you want a "cheap" fix I believe Fram used to make direct replacements which you screw into the oil pan and then their replacement has a bolt/drain feature so the plug stays in place and you have a drain built in. If your stripped and even that doesn't go in right you can permanently install it with a thread bond or something like that (perhaps JB Weld..)
|
Oversize plugs that self-tap into existing threads is another option. It changes seal to a soft gasket material to reduce torque for sealing.
It is also possible to install a timesert or heli-coil thread insert, but better left to professional w/ experience. good luck |
