Oil filler leak

Discussion in 'Mech Tech' started by Max Davies, Dec 9, 2017.

  1. I’ve had a leak from the oil filler seal. I’ve got a new paper gasket and when I took the black neck off I found these two copper gaskets, one either side (as sort of shown in photo).

    Should I keep either or both of them or bin them and stick the paper gasket on the underside?

  2. When I did mine I put the paper under the can and the copper between it and the nut. Working on the basis that the paper just had compression to deal with whereas the copper had to put up with surface drag as the nut was tightened against it. Still sealed...:)

  3. That makes sense. Copper washer paper gasket.

  4. Provided the copper is annealed and soft its worth having also its a spacer that lets the nut tighten properly.

    Otherwise make sure the nut is done up as tightly as possible with one of the two kinds of tools you can use either the slightly tricky screwdrivery one or the better expanding kind.

  5. Thanks, there were two copper washers one either side of the tin (one on the nut and one on the underside as shown on the photo). Are they both worth keeping? I was going to go keep the one on the nut but go without the one on the bottom and just put the papers gasket there as fritt suggested.
     
  6. Jumping on this with possibly the same leaky filler issue. Did the recommended torch test...might redo it at night as it passed a daytime check.

    Thinking to change the filler to this...

    ...as it looks like it would be easier to fill than the standard one - however:
    •Not sure how it would attach as it doesn’t look like you’d get the nut removal tool in there!
    •Also it got mentioned that the breather barb is on the small side, but my breather downsteps to a smaller diameter anyway to go in to one of the Twin Carbs; so not sure it would make a difference or not for me.

    Other option is to just get a replacement original filler...

    ...though the way VWHeritage display it I reckon filling will be rather messy

    Anyone have any thoughts on the above?

  7. Don't, because the breather hole on the blingy one is likely too small, and the crankcase will start pumping itself up. Stick with stock.

  8. Go with the bling one.
    I can sell it to you as just replaced it for stock.

  9. Yes so I actually had a hole in the tin and changed the gasket twice before twigging from another post what the problem was.

    I'd second stock. Just don't keep it 40 years and then sandblast it without checking for holes.

  11. Gotcha
    Sticking with stock. Checked mine again and it seems fine. Sent off a parts order and am immediately regretting not just getting a new filler just in case. Least I ordered a shiny new cap.

  12. Cheers dude. Think I’ll give my current one the bling treatment instead.

  13. Finally gotten around to removing my Oil Filler...only to discover what I assume are non designed holes. It passed the torch test because the holes are in the breather section. Also, not washers on the retaining nut and a well worn gasket - all leading to the minor oil leak.
    Now to order a new filler neck

    Any suggestions on how to clean a slightly mucky thread without dropping stuff down the neck?

  14. Not unusual in my experience. I’ve had two the same. I think condensation rots them.
     
  15. Are decent oil fillers available new? With a wide diameter breather.
     
  16. The usual suspects sell them £20'ish and they must take 10 plus years to rot through, so not bad really.
    It's just another part to replace every now an then.

    Found this replacement Oil Filler on ebay but according to the seller, after 4 days of communications, they’ve told me that my description of having a VW 1975 T2 Late Bay with a Type 1 engine constitutes a “...modified vehicle...” so they are “...unable to confirm correct fitment.” So now i’m confused because I thought that was all standard
    Looks like i’ll just Just Kampers it and get what i’ve already got...minus the holes!

  19. It is standard, and the correct one. I don’t think they know what they’re talking about.

  20. Why didn’t you just tell them you had a ‘VW Transporter T2 Bay Mk2 1975’? That’s all they needed to know to match their list. Adding Late Bay with a Type 1 engine was bound to cause confusion.
