Thumbs up

Hi all

I check my oil yesterday (it was OK) and I decided (for no real reason) to open the engine cap (the hole where you put oil in).

There was a brown substance under the cap itself (i cleaned it) and around the hole. I looked inside and nothing was wrong there...

The brown substance has a butter texture....

Any idea what's that?? Prestone in oil?? Whats wrong?

Thanks!
Henri

EDIT : Oil change was made 3000 km ago (1.5 - 2k miles) with Synthetic Oil (not the 1st time I put syntec in it).

Damn... Is this supposed to happen on a 1998 BMW with less than 85 000km (53k miles) on it!?? Even my old 1991 Sentra with 200 000km on it has never done this!!

Is this something really expensive to fix??

Thanks!
H.


Edit: What would go wrong on my car if that problem was present? (ex: bad trottle, ...?)

Hi, i used to have the same problem on my first eva car which was a ford fiesta rubbish i kno!, but neways, it had a brown buttery like substance round the top of the oil cap! and if i cleaned it off more would appear as i drove it!, it was suggested to me that it was water and or air getting into the engine which created this substance! the car did have a massive oil leak! so would explain where the water was getting in! SO THIS MAY BE THE CASE ON YOUR BMW! i would suggest taking it to a reputable garage and have them check all of your oil gaskets and seals! hope this helps!

This is absolutely correct, more likely to be condensation, looking at your location and if you do short journeys most of the time, the engine never gets to full operating temperature which enables the moisture in the oil to evaporate completely, the only thing you have to be aware of is that if it gets really bad it can start to block up vac pipes and the like.

Best regards David

Thank you all for your replies

Someone talked about an engine flush... is there any products you would suggest to do that? Or products you tried and are bad? :P

I presume I drain out my oil (next oil change) then I put a product in engine then let it run a few minutes, drain out again then put back new oil and filter?!

Thanks

Have a nice day

no... jsut drain your oil, and with the plug still open pour about a quart through the engine. Plug it up and put the new oil in.

Good news! I went to a BMW specialist shop today, the guy checked my "butter" thing and told me that it was only moisture (it's cold and wet 'round here in Montreal during winter). So he told me to drive the car at least one hour on highway to make this thing evaporate. I did, and... everything went fine, no more brown substance in engine!

I'm so happy I didn't need an engine repair !!$$!

Thank you for all your replies

Have fun!

H.
