2011 E70--Oil/Coolant Leaks

[Extendo_Joe]

Hi All-I hope this message/thread finds you well!

I have a 2011 E70 50i w/ N63 Engine.. Owned for less than 1 year (driven a little over 20k miles)

Experienced severe Oil/Coolant Leaks. Visited a BMW Dealer. My Warranty covered the following:

Upper and Lower Oil Pan Gaskets, Bolts and Seals, Rear Main Seal Bolts and Gaskets Engine Compartment Bulkhead and Strut Tower Braces.

After service from BMW dealer and fixing everything my warranty covered I am still left with the following :

Turbo Charger Coolant Feed Lines (Quoted $2960 from dealer)
Crankcase Vent and Crossover Pipes ($1300 quote)
Turbo Charger Oil Return Block ($3021)

Any advice on places to purchase parts? I have an independent BMW shop I can go to that I'm fairly sure they will allow me to bring my own parts.

Should I throw in the towel and try to trade it in? I know the seals, gaskets and oil consumption will be an ongoing issue.

Are the 2014 and newer engines more reliable?

I would find a good independent mechanic if you keep the car. Dealer quote the OEM specified hours to fix each item, even if there is commonality to each job.

Can you wrench? The parts may not be anywhere close to the cost quoted.

Also, when I buy a car I'm usually "all in" even if I sell them in a few years. I make sure to "fix to keep" in case I actually DO end up keeping them. These cars are great to enjoy when they're running like a top.

Find a shop, get to know them and trust them. Ask around. When you find a good shop you can trust, stay faithful it will pay off in the long run.

Yup, had all of those leaks on my x5M at least 1x. All are very common.

So the turbo oil return block seal is cheap. Like a 20-40 part but it’s all labor to get to it. Negotiate with them as the oil return block requires removing the turbos and turbo oil lines anyway. So they should do the new oil lines for the cost of parts when doing the return block. Figure it should be multi hour job. The oil lines will leak eventually too so replace them while their at it,

The Ccv vent lines are covered by a bmw extended warranty for 10/120k. The parts again are like 200-300. Had these done on my x5M

The coolant lines at an Indy where like 300. Or buy some hose clamps and diy for less.

Filtered air ducts also go and are about 1k each

P.s. if your thinking of trading anyway. Skip the reminding issues and trade. The vehicle is probably worth about 7500 on trade in with good condition and repairable defects. If you have the services above done at the dealer it exceeds the value of the car.

Really the coolant lines, oil lines and turbo return block seal should all be the same job, and you can ask them to combine it and discount the labor and provide your own parts. Remember the dealer will negotiate. If not tell them
You’ll go elsewhere.

In reply to this question, I would do as little as possible and get rid of it.
I’ve had two cars with N63 engines and had nothing but major trouble. I do most of my own work as a hobby, but could not get past the troubles. Even a very good Indy was stumped on the cars. Would have cost me very little as I have fantastic warranties, but it got to the point where both cars were malfunctioning more than they were functioning. I have four cars, but will not have a N63 anymore.
Also had nothing to do with oil loss. One car came with upgraded cross line for crankshaft ventilation, and I fabricated the cross line on the other for a pittance.

The parts aren’t that much. $300 maybe? The labor is all one job. The other issue here is I think you drive too much for this. 20k a year is a lot.

Have you looked at the bang vs bmw class action settlement? You may be able to get several of these covered for cheap (free labor due to valve stem replacement or engine replacement). Insist on getting an oil consumption test
