Minor oil leak from turbos, getting fixed under warranty. 27k miles. Driven hard and put away wet it’s whole life. At least someone’s been using it the way it’s meant to be used.

Tongue in cheek. Not an SL. This is one of my favorites. Exhaust is in the middle

Put away wet?
I have a car with two turbos now... Do you have any recommendations so that I’m never an annoyance?
I’ll never get an SL if that helps, not that I can afford one anyway.

They’re going back in, oil return line seals were leaking, not the snails themselves

Figure of speech meaning it was abused.
Stay on top of your maintenance schedule. This is my job and I love it, no annoyance here! Well maybe a bit, because this is tricky to work on, but it’s all good!
Not an SL. Exhaust is in the middle but you should buy whatever makes you happy! I’ll only judge if it’s a 129 or 140.

There’s actually not a lot of MB that have center exit exhaust. Also is it just a GT as i expect since it has that many miles on it? I don’t think the other variants have been around long enough to get that many.

Exactly. The builder plaque tells us who to call when we can’t figure out how to fix it.

oh, hot vee!
I just wondered if twin turbo cars need some special precautions... i’ve heard you need to let the turbos chill for a moment before turning the car off?

Edition 1 GT-S. And I didn’t mean center exit, the tailpipes are not center exit, I meant the exhaust is where the intake should be and vice versa. I just did some work on 205 C63 with the same number of miles. Some people drive the crap out of these things.

It doesn’t hurt, but with modern synthetic oil and modern cooling system technology it isn’t so important as it was years ago.

Ahh gotcha. 2 nearly new cars with a ton of miles is surprising for AMG. That’s really cool.

I guess when driven hard shortly before driving it’s helpful?
But when just driven casually it’s no issue. Right?

If you’ve been driving hard, say towing or hauling a heavy load, or track time it is good to let the vehicle run for a few minutes to circulate coolant and oil. These days they design turbo vehicles so that the coolant siphons through the turbos to cool them even after the engine turns off and the water pump isn’t circulating coolant. Also oils are much better than even a few years ago and are much less prone to coking up bearings like they used to if you turn off the engine when the turbos are hot. If you’ve been driving around town or even on the highway I wouldn’t worry about letting the car run. If you just did an autocross or 20 minute top speed run down the autobahn it would be a good idea to let the car idle for a couple minutes so things (oil, coolant, turbos) can cool off.

Can you define these days? Asking for a 2014 Ford Focus 1.0

I do live in a very hill area and while I don’t tow I do have the car loaded most times.
I did notice it takes a lot longer to cool than my jeep

Actually, that’s a really interesting manifold design. Am I seeing correctly that there are only 8 screws per bank? And all of them are co-linear? How does the bottom part of each manifold seal?

Look down in the valley. The remaining 16 nuts are still there. They hold in brackets that the manifolds slide into. The bracket and the manifolds are tapered so when you tighten the top row it applies pressure into the taper.

Oh hey! That’s really clever, bet it makes getting those manifolds out a little easier (or rather, possible)

My F-150 has a secondary electric water pump that circulates coolant through the turbos for a period of time after shutdown. With the mass adoption of turbos these days, OEMs seem to have gotten pretty good at keeping them alive long term without much in the way of special treatment from the operator.
![]() 04/13/2018 at 18:15 |

Well that’s a bit more car than I’d expected ...

Exactly the sort of thing I was referring to. Many of those are even on a colder temp cooling system from the normal engine cooling system.
![]() 04/14/2018 at 00:09 |

They plumb the coolant lines so that the cold feed comes in to the bottom of the turbo and the hit return goes out the top. After you turn the car off the heat from the turbo will keep the coolant circulating since the hot coolant will rise out the top return line and cold coolant will get pulled in to the bottom feed line. Siphon probably isn’t technically correct, it would probably be more accurate to say that the coolant keeps flowing due to convection, but IIRC Ford refers to it as siphoning in their manuals. I’ve got a 2011 F-150 with the 3.5 ecoboost and Ford specifies that the coolant system is designed to allow coolant to continue flowing through the turbos after shutting down the engine.

There are a lot of factors that determine how long it takes for a car to cool off. Turbo vehicles generally have higher oil and coolant capacities in addition to the turbos themselves. That is a lot of extra fluid and metal that needs to cool off after you shut the engine down.
