Please identify seal

[neilpaku]

I had a look on the parts diagram on Jim Ellis Audi and could not identify the seal that's adjacent to #5 cylinder on the bottom side of the lower engine block. It doesn't seem to show on the diagram, and the ETKA diagrams on partscatalog.info are no longer available. The seal is about an inch / inch and a quarter square with a "notch" out of one side. It looks like it seals a coolant gallery.
I'd post a photo but my account here no longer lets me post pictures.

If someone has a link to an ETKA site, I can check there (partscatalog.info doesn't work anymore). I have the other three seals on that interface but just missing this one. I "could" just put some sealer on it an call it a day but if it leaks....

Cheers,
Neil.

can you upload a photo to imgur or something then link it here? I am having trouble visualizing what you are talking about. Or maybe I just haven't had enough coffee yet..

I'm not sure what you mean, either. Is it one of the parts shown here: http://www.nemiga.com/img/catalogs/e.../247103400.png

Hi, I will see if I can get a photo posted somewhere and link it. Meantime, in that photo you posted, it's not #10 or 17 or the other one at the back #13. The other seals shown are on different interfaces (e.g. between the upper block and lower block, and between upper oil pan and lower oil pan, etc.)

I've bought all those but there are actually four seals on that interface. The one I need is right at the very front corner under #5 cylinder.
I'm wondering if I should just buy the remaining seals that are listed on that page that I don't yet have in the hope that it's one of them.

Here's a picture of the upper oil pan. That hole in the bottom right corner, just below #5 cylinder, is where the seal mates to. The seal is shaped like a square, with one corner kind of "scooped out": http://s1318.photobucket.com/user/au...s2p8r.png.html (sorry about the ads on that site...). The picture was posted in a thread on here http://www.audizine.com/forum/showth...=upper+oil+pan and is his last photo

hmm I'd have to guess it's #9 which is part # 079103121G. It's really hard to tell from the illustration because it doesn't show where each seal goes. I really wish Audi did a better job of showing a correct exploded view diagram, rather than just randomly throwing parts on the page without showing where they go (most parts you can tell how they go together but a lot of little things like these seals seem to be just randomly placed on the page). Don't assume that it goes between the upper and lower block just because it's positioned between them on the illustration, I don't think that's meant to show where it goes (it also makes it look like #'s 11,12, and 15 go between the upper and lower oil pan but they don't). Best bet is probably just to get all of the ones you don't have yet. Or bring a pic to a dealership parts dept and ask them to figure it out, so if they order the wrong one it's on them.

Yeah I think I'm just going to order the others that I don't have. I was having a side conversation with Spike about the quality of these parts diagrams and listings. If you want to see the gold standard of a parts catalog, look at an old school Caterpillar book. Everything is drawn to scale, with each part shown in its assembled position (or exploded when that's appropriate for large parts) and the diagram doesn't have crappy reference numbers, but instead has the actual part number with a line connecting it to the part in the diagram. At the back of the book is a alphabetized listing of the part numbers with the page on which the part is found. I have about twenty of these manuals for different machines and have yet to have a problem identifying a part. That's what Audi and these other characters "should" do but I guess there's not much value in it for them these days because we're such a throwaway society....

This is likely off the mark, but are you sure there is even a unique seal there? There are those random spots (usually pan-types spots though) on this car they just expect you to make your own with a gasket maker compound and no gasket actually exists. I've not torn into my block in that level and am not familiar with those parts you are talking about, so I am just tossing it out there.

And I agree on the parts diagrams, they are pretty awful. It's a shame because there is some pretty creative and ingenious engineering done to make this motor and get it all to fit, but it seems that creativity and ingenuity didn't make it to the drafting group

Hi Badger, it's a good point you make and is a reasonable check. In this case though, there really is a seal there. It has the groove laid out in the lower engine block and the current seal fits in there perfectly.

[neilpaku]

I think you're right. That's one of two seals I didn't order so I have now. I didn't order it originally because it was displayed between the lower and upper blocks, but I don't trust that placement anymore. Fingers crossed! It'll be good to get the bottom end bolted back on and get the heads refitted. Wife is breathing down my neck as she wants her car back before school starts. Not sure if that's going to work out : )

Found some photos to post showing all the seals (1-4) and the one I'm after (#4):
