I found a washer in my oil drain pan

After draining my engine oil and final drive oil I found a very light weight aluminum colored washer in the bottom of the oil drain pan. The problem is I had already put everything back together and filled up the oil.I had no choice but to drain the motor oil again to check the drain bolt.There was no washer when I removed the drain bolt so I put the washer where I think it belongs and filled up the oil again.My question is,does the oil drain bolt have an aluminum washer?

These 3 should have a washer fitted: drive oil refill bolt, drive oil drain bolt, and engine oil drain bolt.

When you remove the engine oil drain bold sometimes the washer sticks to the sump temporarily - same thing happened to me. I just put it aside and re-fitted it on the next oil change - no problems what-so-ever.

Yeah. . .I find that when I change the oil on two wheelers sometimes the drain bolt washer sticks to the oil pan. Knowing that I try to make sure I get it all when I unscrew the drain bolt and wipe everything off immediately and look for any traces of metal particles or dust. Really hate to drop anything into the oil drain pan. I usually get multiple uses out of a washer and then eventually replace them with a new one. 8)

The drain bolt washer is a single use crush washer.
Doesn't hurt to re-use though.

^ That! ;)
Yes, "Crush" is proper word used for the washers in this topic. Also referred to as sealing washers.
The aluminum washer "crushes" slightly as you tighten the bolt. Thus better sealing (no leak) result.
mike11148, did you receive an Owner's Manual with your 2016 PCX? It's a helpful little book usually found under your seat in a small pocket. If you didn't get one, I suggest you ask for it.
By the Way....Cheers for doing your own Oil Change!! 8) :P

Order a baggie of the crush washers. It's not necessary to change it every time, unless you tighten the drain bolt like a gorilla.

I reused the one on my '98 Civic for about 150,000 miles worth of oil changes until it started to leak, because it had been crushed to the point that it was starting to flow up the bolt threads and hurt the seal.

For the future, make sure that washer is in place when you put it all back together. If you don't have it, you will SURELY have a leak.

In the olden days..but after GN2s times, they were copper and you could re-anneal them.

Now I just leave the sump bolt and use a vacuum pump. Hallelujah. Seems to fall on deaf ears here though.

Yep - mine's been reused 7 times now - no leakage.

Is it a manual pump like something you would use to pull oil out of a bottle? I still have something like that for filling up lower unit gears on an outboard motor. You need to be able to draw out the oil all the way from the bottom of the engine though with a straight shot in for the tube. Then you have to make sure all the old oil is out of the tube before you put it away.

If one has a vacuum pump then great idea, I've got a couple of Honda EU2.0i generators that I change the oil in in a similar fashion by using a syringe and some tubing. In the absence of a pump though, undoing one bolt with a socket isn't particularly difficult.

No. It's a specific pump for framing oil out of the sump.

It's what most garages will use especially on cars. Quick, efficient and clean.

Negative on that, sir. Some may. The problem with doing so is that the oil (especially hot oil) rushing out from a drain plug scavenges the bottom of the oil pan/sump and purges sludge from the bottom. Some pans/sumps even have a lowered portion or drain ridges where the plug attaches to assist with this, both my car and truck do.

Siphoning oil out isn't necessarily bad, sometimes it's necessary because the plug is difficult to access. But it doesn't help remove the sludge buildup. Each to their own, you like a siphon/pump, I'll remove the plug and wait until it's a only a slow drip left. Whatever.

Quick & Clean - OK I buy that. Efficient - Nope.

I put this on, 4 changes later, 2 years later, it still works perfect. Never worry about washers or cross threading again. Never spill a drop. The bike lives in a condo garage so this is important. Easier too.....My changes are 10 minutes.....

I like it - never thought of that.

In all honesty though, doing it the conventional way really isn't any particular challenge. If anything, I think I made more of a mess the first time trying to get the fresh oil in before I bought a funnel for the job. For the old oil I just loosen the plug - put an ice-cream container under it - and undo it by hand. On a slow day I might get a bit on my hand, but a disposable handi-towel makes short work of that.

In the old times we only argued about what oil to use, dyno or fully synth, additive or not blah blah blah.. o_O

I'm just messing around, i'm not that old yet. :lol:
