Default Made mistake with crush washer need advice.

Ok I just changed the oil on my Forester. Changed oil a ton of times and I typically always re-use the crush washer. This time when I took the oil bolt off the washer stuck to the pan. No big deal.

Well I changed the oil and put the bold back in filled it up and was done. However when emptying my used oil from the collector I saw the crush washer. It had fallen off and I did not notice it was not there when I put the oil pan bold back in...


I am just worried about the bolt falling out- Not sure what all of the crush washers functions are. I know it is meant to use so you do not over torque the bolt but does it also keep the bolt in???

IS it ok to not have a crush washer installed??? I have new ones I can use for my next oil change- But will I be ok between now and my next change???

I have forgotten it before without ill effect. I am not saying it absolutely couldn't fall out, but I would highly doubt it.

I believe another function of it is to crush so that it provides a better seal for the oil. As long as its tight I would think it would be ok, though you may want to change your oil a little early. Also, check daily to make sure its tight and it doesnt leak since theres not much knowledge on the subject. Just my opinion.

I went through at least 20 oil changes without the washer, you'll be fine. Now I use one, but still, if its tightened, you're fine. Put one when the next oil change comes, I wouldn't worry about it.

Keep your eye on it and check under the car for leaks now and then. Before it fell all the way out it would loosen and leak, so hopefully you'd have some warning. It will most likely be just fine.

Ok. Sounds good. I don't care if there is a slight leak of oil because right now I have oil leaking all over. I think it is the spark plug gasket as that seems to be where the leakage is coming from.

Last time I had it in to th edealer they told me about this but I am puttign it off as it is not leaking so fast that it is an issue. But I will not be able to tell if there really is a leak from the bolt as there is oil from above....


By the way is the plastic cover that covers the bottm of the car - under the engine bay really do anyhting?? I mean I knwo it keeps road crap from gettign up into the engine compartment but the car is old and this think is breakign and cracking. Jsut wondering if it would be a huge aerodynamic effect if I removed it??

you should be fine, but i recommend definately getting a gasket/ washer on there next time, because while tightening the plug back in, you can easily strip out the threads in the pan. that is a p.i.t.a to fix, especially if you do this at home. walking to the nearest autozone kinda sux. trust me, ive seen this plenty of times, as i used to work at an oil changer. but dont worry too much, just be sure to do it next time

your bolt wouldn't likely fall out as said earlier.. but oil may leak.. you can tell if oil gets on some of your exhaust parts and while your car is warmed up, it'll burn and you'll see some smoke

If you are hitting ludicrous speed, you should have it on. If not, the undercover is pretty much just for keeping stuff clean(er).

The difference between the engine compartment on my WRX and my old '04 TS (stock, without cover) after winter was huge. It really does make a big difference there. Living in the north I'd say you want it on there, cracked or not.
