Oil fill cap size
So, I just picked up a few things from Parts Place..and one of those is a new oil fill cap. The old one was pretty beat up and didn't seal well..so I figured why not.
I went to put the new one on, and it won't latch in. I stuck it on the bench next to the old one, and the old one seems a bit taller.
The new one isn't tall enough to clear the rolled lip inside the tube that you turn the cap to secure with..but the old one is just too dang loose. What am I missing here? Or, is this just a case of a bad part?

I really think these repro places NEVER try installing their so-called parts on an actual car.
BTW - the "seal"/gasket is sandwiched between parts of the cap that are spot welded together. Maybe you could make a new seal and slip it behind/on top of the original seal on the cap...sort of tighten up any excess clearance b/n the seal and the oil fill tube.

My original is pretty beat up as well, that was another reason I was good with replacing it.
I'll keep an eye out for a good replacement piece. Yes, I could just tear them both apart and make 1 good one..but I'm not "that" crafty.. lol

Thanks Rick! - good to see your posting and info on the SOLUTION to a loose seal/fitment on the cap. That's typically the only thing that is "wrong" with an original cap. Time to go to the parts store and stock up on the Duralast "donor" caps.
Now that Rick mentioned it....Ames Performance sells a rubber seal/gasket for use on radiator caps. I have one and will check to see if it fits on the oil cap as well. Probably costs more (definitely will w/shipping from Ames) than the locally available Duralast cap so not as good of a solution.

There are plenty of these caps out there that won't be beat up...if you mean the visible-once-installed parts of the cap.

Alright, my buddy came through..I think.
It's a Gates 31066. I got it out of the box and noticed it's much taller than the Parts Place piece. Pulled the old cap off, stuck the new cap on..its pretty dang tall.
it seems pretty locked in, especially compared to the original cap. I'm just not sure how sealed the "gasket" is around the top of the tube.
I suppose we'll find out.

Alright, so after driving around all weekend with no visible issues, I drove it to work this morning and it seemed to be smoking pretty heavily. While the oil level didn't seem to have budged, I did notice the air cleaner lid looked a bit wet. Upon removing the new cap, I noticed it too doesn't seem very tight.
I'm just gonna go back to the one I had originally on it and just be sure not to bump it. That should eliminate one of the 4-5 sources for various leaks that reared up this morning.
