I don't see why I couldn't put an o-ring on the oil drain plug instead of the crush washer. That would make it a lot more reusable. Is this a good idea?

You will sqash the o-ring down to nothing, probably tear it, and it won't be reusable. The crushwashers work perfectly fine unless you don't clean them and the engine case off when you change the oil. Any little bit of dirt will put pits in the washer and can cause it to leak. If you have a good crushwasher you won't have a leak unless something is wrong w/ your engine case or drain bolt.
Think about it, crushwashers have been used on hydraulic brake hoses for a long time and if they can stand the pressure w/o leaking then they will have no problem sealing on a drain plug. Cleanliness is the key.

Okay. I just think that an o-ring is better. I really don't know why. I just do.

o ring will not be reusable. you will smash it into nothing.

arlindsay1992 · 06-18-2006, 08:00 PM

Yeah I see. Oh well...

if there was a grove in the bolt (like the cam cover for instance) , then it would work but still would be better than the crush washer if it was dirty.

Just use a crush washer. If you are afraid that it will leak, wrap some teflon tape on the threads of the oil bolt.

The crush washer serves an additional purpose an o-ring doesn't, it crushes. Yeah, sounds lame, right? The way it's supposed to work, is you start tightening that bolt till the washer 'crushes' and you know you've nailed exactly the right torque. Next change, toss the washer, install a new one. Go a lil tight on the bolt, the washer should take the strain before you risk the threads.

(BTW, you are technically supposed to be changing that washer any time you undo the bolt.)

yup, but no ones does. along with myself.

arlindsay1992 · 06-19-2006, 11:27 AM

I know it crushes and seals it. Okay I'm not going to use an o-ring.

Nice!

arlindsay1992 · 06-19-2006, 03:11 PM

That's cool but I don't think it's actually worth it. I don't have sealing problems, I just wondered if an o-ring would work. By the way, Motarded, funny signature.
