Oil cap leak, source for replacement seal?

[Vincent Brick]

I swear I have seen talk about this issue on here before, but I'll be damned if I can find anything here or on Google now that I need the info. Please be gentle, I searched.

My oil cap appears to be seeping some oil that is getting on my valve cover, looked and sure enough the seal is hard and feeling very much perished. Realoem indicates the seal is not available separately, but the rest of the cap is in nice shape. I also read that the non-OEM caps can present problems, which doesn't shock me.

tl;dr: Are there any sources for oil cap seals or do we just have to buy a whole new cap from BMW? Any other options?

Thanks!

buy a new cap - 10 bucks maybe?
or rip your existing gasket off and go "in search of" at your local small hardware store

Yeah, I bought a new cap and just swapped the old seal for a new one. Ultimately, the springs on the old cap were too worn out so I used the new seal with the new cap.

Are they really that cheap? I'd spend $10 in gas just to get to a hardware store that *might* have stuff like that. I was expecting it to be a lot more.

You know my doctor, right? Dr. Vinny Boombatz?

Febi-branded oil cap is $2.56 at RMEuropean. PN 11121716993

Husker BMW (now called BMW Direct Parts) has the OE BMW cap for $6.74

ha! I was just coming here to ask if you all would trust a Feb cap, I found them at my local Euro parts wholesaler for under $3/each. Its the old school round cap too which I prefer over the later square ones.

Hell, even ECS has the same Febi cap for ~$3.50 SHIPPED, and they're always kinda expensive.

I don't trust Febi for everything anymore, but I think I'll be ok with their oil cap. My works-on-E30s-for-a-living buddy seems to agree. Thanks everyone.

[Rontgen]

I did the same. I'm not a huge fan of Febi, but how badly could they screw up an oil cap? Haha.

Worst case, I'll throw it away and spend $7 on an OE cap. Or just replace it with a dress sock. [emoji6]

[Vincent Brick]

And it seems like the legit places stock it, retail and wholesale. And yeah, for $3.39 shipped from ECS I'll take the gamble, like you said I'll go OEM if it really somehow sucks.

I saw that dress sock thing too lol wtf

[jdt10768]

a pair of socks might cost more than a new oil cap,
AND you'll have oil all over your engine bay, smh

[Vincent Brick]

Seriously, at less than $3.50 shipped I am confident I got the cap for less than a pair of dress socks, even a pair from TJ Maxx or Ross. :)

Do not buy Febi cap. I bought a new Febi oil cap last time and it rattle. You can hear the rattle if you shake it. It's $3 for a reason. The gas cap seal from (e34, e30, e36) and oil cap seal are the same. I have used e36 gas cap seal on my e30 oil cap and fit perfectly.

[digger]

genuine ones are like $8...

[e30fix]

buy the oem one for 8$. its better than having to order another if the febi fails.
