I changed my oil a couple weeks ago and left off the crush washer accidentally. I went to the auto parts store and all they had to replace it were the fiber ones. I wanted to do it quick so as little oil would drain during the process so I bought a new bolt too.

Now the car smells likes it's burning oil off of some hot surface. It's been about 500 or so miles since the change. I can't locate exactly where the burning smell is coming from.

Could the smell and the fiber washer be related?

maybe, just crawl under and look.

if it's the correct part and installed correctly i can't imagine that being the issue. you know how many oil crush washers i've replaced - none. i have never replaced one. occasionally i'll notice one wet, but i've never had one all out leaking any significant amount.

point is - if i've put a hundred thousand miles on a few subaru's and many 10's of thousands on various others over the decades and never replaced the washers i think one oil change is probably a drop in the bucket.

I once tried to leave the old crush washer in. It did not leak it POURED.

I switched to a copper one and stll using it. Probably for 15 years by now.

A month ago I bought a crush washer from a dealer for my new Forester and they charged me $1.20. What a rip off! I did not use it, because I bought another copper one. So far so good! No leaks.

Seems like the problem is related to your FELT washer. Get a copper one or a Suby one.
Note that the washer has a raised side, which goes to oil pan(if suby).

I put in a Fumoto valve many years ago, and haven't touched a wrench when doing oil changes since. Less mess, and no skinned knuckles from slipping wrenches. It takes a little longer to drain, but I usually start it draining and go do something else for a while anyway. It's a whole lot easier to live with than wrenches, washers, splatter, etc.

I agree on the Fumoto Valve. I have one on all of my vehicles and love it. No drips, no leaks, and no fuss. I can change my oil with no wrenches involved.

I like the real crush rings. I buy them in bulk thru my shop. The Fumoto valve is pretty neat but at $25 for every Subaru I have it adds up.

Since the question was about a fiber washer I forgot to mention that on my Camry the fiber washer got stock to the oil pan after the second oil change (year 2004). It is still there! No leaks!
