Oil Leak after Changing to Castrol Edge 5W40 - common?

Folks

Just bought an 04-325Cic with 66K miles. Had another 4500 miles to go before the oil had to be changed, but I decided to give it a fresh oil change.

I bought Castrol Syntec Edge 5W40. It met the BMW LL-01 spec and it was even labeled on the front that it meet's BMW standard.

One day later, I noticed oil on the garage floor, under the oil pan. I havent found the EXACT location of the oil leak, but there was oil along the oil pan gasket (dripped there over time?). Also noticed the bottom of the dipstick was saturated.

My question though is, should I experience a leak like this after changing to Castrol 5W40? Is this common? Or did I just miss this leak before I bought it? I had the car for 5 days before I changed the oil and then the fun began

Drained about 6.5 quarts. Poured in 6.9 quarts. Dipstick showed it was perfect after filling.

Also noticed the oil had green tint. Never seen that before in all of the oil I've changed. New to me.

Noticed a LOT of gunk in the old filter. This drop in filter is also new to me.

Shouldn't be normal in any way.

Take a old microfiber towel and wipe down the whole area until you don't see any oil. Wait and see where the leak is coming from.

You just found an oil leak! Nothing to do with your change.
BTW, what change interval are your referring to? Most here do 7500 miles.

Oil where you say could be a defective seal at the dipstick tube, OR a leak somewhere in the CVV spiderweb of tubes in this vicinity. In that case you'll be doing a CVV replacement soon.
Or you could have a leaking OFHG.
Investigate all the above and let us know how you resolve this.
Clean stuff by spraying Brakleen to wash away the oil.

Sounds like you did it right. Did you change the oil filter cap O-rings (1 big, 1 small) ? I second wiping down possible leak areas and monitor for leaking oil.

FYI--I do my changes not at 7500, but 5000. Use to running cars to well over 200k and perhaps 7500 works also, but I will stick to 5000.

You're wasting your money and probably actually achieving less overall lubrication. There's no reason to change a synthetic oil at 5k (in a car designed for synthetics). There are a couple of examples where even 15k OCI cars have made it to 300k and beyond with no sludge or varnish whatsoever

Areas around the dipstick and drivers side to look at carefully.

1. Oil Filter Housing gasket, where filter housing meets engine block.
2. Make sure you cartridge filter is not leaking from the top.
3. Very common problem on these cars, CCV hoses. Expectially the CCV oil drain hose from the bottom of the CCV to the side of the dipstick.
4. Dipstick O-ring can leak, but not usually a big source of leaks.
5. Power steering hoses and reservoir, they leak all the time. After about 6 years they start to saturate and leak.

Appreciate the tips. My journey will begin this weekend. Will look at all of these areas and some more. Awesome location of knowledge, this site is.

Also thinking, while I'm in there, may also tackle the cooling system overhaul. I suspect I am 1/2 way there with taking off the parts, might as well go full-monty on it. Not to mention the transmission pan and rear-diff fluid (while car is on ramps). Just hope the weather doesnt hit 65 or more, then I'll wish the car was back on the road.

Will inform once this massive undertaking is complete (maybe next year? )

Did you see my head at 96K miles? Cannot be cleaner with 7500m changes. And Blackstone Labs just told me that my latest oil which I ran to 9000m could go further as it tested like new.

Make sure you replace TWO small O-rings on the filter cap.

They don't always come with the filter kit. The size is 7 X 2.5, and you can order from McMaster Carr in Viton for $10 per pack of 25, McM-C number 9263K696.

They've never come with any filter I've ever bought.
Very cheap at the dealer where I buy mine.
Guy at parts counter told me he's never had a request from the certified BMW mechanics to get new small o-rings when doing an oil change.

Waste of money. There is evidence that the oil used in our cars does not reach full effectiveness and protection potential until over 6,500 miles.

Sounds like a leak from OFHG or CCV drain pipe like jfoj mentioned.

Remove the plastic underbelly and see how much oil is there. That thing can hold a lot of oil. Once you remove the plastic piece and clean the area, it will be easier for you to locate the leak.

Castrol edge 5w40 is fine to use as its LL-01 spec. Although in winter you might want to run castrol edge 0w30, not much of a difference.

Now, interesting part; you say the liquid is green. Make sure its not the coolant. Smell/touch/taste whatever you fancy to confirm its not coolant. OEM BMW coolants are blue, but since you just bought the car PO might have used generic green coolant. Check the coolant level and for leaks on the cooling system. Its good that you are doing an overhaul on the cooling system, but first make sure the leaked liquid is not coolant. If it is, dont drive the car until you figure out what it is and where it is leaking from.

Edit: did you remove the old crush washer and replaced with new one at the oil drain screw, when you changed the oil? No crush washer or double crush washer will lead to a leak.

Couple of answers:

1. Crush washers: yep, used the new one that came with the oil filter. thru out old one. No leak at the oil pan bolt.
2. Color of Oil: I shoulda mentioned that this was the color of the oil in the container, right before I poured it into the engine. Never seen green tinted oil like Castrol Edge MST
3. Will be ripping into the top part of the engine to identify the true source of the leak.

I suspect you can drive around without the plastic underbelly, correct?

Appreciate the help guys.

No problem driving with not plastic underbelly.
Just keeps things clean and aerodynamic.

Did some research this weekend. Pulled out the air-box and other simple-to-move parts. Looks like it is the OFHG as indicated by the photo I attached. Oil has been catching in the waffle-cone area.

Also, pulled the under-tray carriage (nice unit b/c the screws stay intact, unlike my IS300). Simple to remove and put back in place. Oil source seems to the the OFHG. So parts are on order and work will begin in a week or so.

Question, I suspect you do NOT lose much oil during this OFHG replacement activity, is that correct?

Thx for getting me to this point.

You'll not lose any oil if you remove the oil filter first and let the oil from there drain back down to the crankcase before removing the OFH.
You do know that each of the six bolts is a different length, and have to be replaced exactly in the same spot?

See the six bolt holes for the OFH here, and see how much oil collects in the waffle section:
