What did you do to your LS today?

Perhaps try some of those detergents prior to oil changes, IMO I'd get that gunk out, can't be good for it.
There are passages inside engine blocks if I'm not mistaken (i'm no motorhead) that require oil to move around,
all that build up of gunk and crap can restrict flow and end up in premature engine failure.

I could be wrong but I don't like the looks of something like that, myself I'd be busy getting rid of that problem in a hurry.

I'll take category "BMW Fill Tubes" for $200 Alex!

I stand by my statement which was "I promise you that the M54 engine in my 325i does not have a fill tube." The windshield washer fill tube (a non separable part of the reservoir) is not a part on the engine.

It's not really gunk, it's a mixture of water and oil.

Since the ls doesn't have known head gasket issues and I'm only at 80k miles, I think it's just condensation.

How did you get that off. Mines been leaking around the neck.

Also what is the acceptable amount of foam under the cap??

The first time I got it off was by accident. I knocked it off. If you look at the close pic, you can see where its broken at the back side of the hole. Another plastic part. From what I can see, a flat head screw driver inserted from the front like trying to get under the o-ring then a gentle twist to the left with the screwdriver while pushing the tube back and rotating it slowly counterclockwise. Beware: if it feels like its not rotating, don't continue because it is prone to break.

About the foam under the cap, you shouldn't have any.

Popped in 5k HID lows and 3k fogs.
Looks good, glare isn't anywhere as bad as I thought it would be. Will snap a pic or two when the camera is charged and I get around to it.

Ideally, no there shouldn't be. I've never had any, but I don't live where it gets really cold and I have hardly any really short trips. If he lives in a cold area and does a lot of short trips, what he is seeing is to be expected.

Also remember fellas, start with no more than 6 QTS of oil if you are rolling 2nd Gens. The pics kinda look like sloshing to me too. I think we've gone over this in 2012 IIRC. I could be mistaken and it was on another forum but it counts here too. After the initial 6 QTS, it can be checked the next day for proper level.

Again, I disagree. The 2nd Gen V8 calls for 6.5 quarts, but I find that 7 brings it to the max mark. I've never had any problems with that. It's better to be high of the margin than low.
 
Can someone please elaborate on what qualifies as a short trip? I have always been aware of this concept and if I need to go somewhere close I usually drive around a bit just because I don't like the idea of short trips on an engine. What I am asking here is, how short is a short trip? Trivial, I know, but just curious.

I would say not getting to operating temp is a short trip.

Sloshing? And I'm with joe, 7 qts is what I put in.

I agree, and don't get me wrong. Short trips now and then are okay as long as there are still long trips mixed in here and there. I think you'll only see problems if most/many of your trips are short.

Yeah post up some pics. I'm curious how it looks as I want to do this also...

OK guys, not trying to be a jerk or anything. I thought the general consensus in the automotive community was foaming oil is bad due to the loss of certain protective properties as a result of said condition. So, I am confused why there is no concern over the risk of over filling the oil when there is a risk of damage to the engine according to the manual. We know there was a spec change in the manual for the oil capacity. I had my oil changed and I was specific about refilling with 6 QTS only. Sure enough, like idiots, they filled it with 6.5 Qts. Checked it the next morning and it was over filled so I took it back to have them re-work it.

This may sound like some sort of nonsense but, I have read too many post with issues related to the LS not having any get up and go when called. Then we have an issue such as this which may have some effect on the operation of the VVT mechanism. I don't know what to say about putting 7 QTS in and have it read at the max mark. I would be suspicious of some sort of modification.

No, foaming of the oil is bad because it usually means water/coolant is getting in the oil indicating problems i.e head-gasket.

In my case I live in a messed up state where (I'm not making this up) was 50 degrees one day and 14 degrees the next with 6 inches of snow on the ground. Moisture collected at the highest point creating the frothy foam under the cap and the top of the neck (normally would get burned off by heat but I don't drive far enough for that to happen). No water was in the oil in the engine. The cap in my cousins mini looks exactly the same.

7 qts fills mine up to the max mark. Engines do consume (and leak) oil (mine a little less than a quart every 5,000). So you're running your engine a qt low if I understand? I would much rather have my engine filled correctly.

Was going to tonight but my camera charger is MIA...swear I lose stuff to gremlins sometimes.

I'd also say check out Ghost_Ls8's pics he's got the same temp bulbs (and his car is hot!)

Actually my car is running at the max mark. I don't burn any oil at all. I don't add any additives. My engine is filled to the spec of the original 3.9 litre V8 which is 6.0 QTS because I was advised to do so by a reliable source.

Now that I'm more awake and not feeling zombied out, I am going to approach this with a bit more open mindedness.

My and my source's theory behind keeping the original oil capacity spec. Is based on the fact the change in specification coincided with the VVT update. That would be logical in that case to include the additional oil for the VVT mechanism itself during the initial fill. That being said, our logic would make an educated assumption that the VVT mechanism and the plumbing leading into it would not be completely drained during an oil change. With that, we have an initial oil fill capacity of 6.5Qts and a refill of 6.0Qts.
