My 560 is leaking everywhere!

Just a rant. My car had a small coolant leak at upper hose. I had unclamped it to install a new t-stat last summer. The hose, with its hard rubber, did not make a good seal. So I thought replacement would fix the slow leak. There is another, passenger side front intake to head. Ugh!

My trans is leaking fluid to the point where is flares on the 1-2 shift. Again, thought I found the leak and corrected it. I must have another. 1.25 quarts later its back in the right level. For now.

Front caliper appears to be leaking. Saw the brake fluid level was very, very low. Topped it off and its holding fine. I think the recent weather (snow) caused the ABS to run a lot more than normal. Must have pronounced the leak. Got new calipers in, both defective (broken/bent bleeder valves). New ones on order.

Oil is leaking from somewhere. Possible the oil pressure sensor or maybe the oil filter housing gasket. Either way, there is a tiny leak that needs to be fixed.

And dont get me started on the SLS.

I think the only thing NOT leaking is the power steering. It did at one time a little then stopped. I give it a week before it starts again.

I just hope it hold up til late spring, when its a little easier working on this stuff in the driveway versus the garage...

And so goes used car ownership. Driving and maintaining a car has its ups and downs. Sometimes you rock along with 100 thousand trouble free, maintenance only miles and sometimes it seems like you just can't get a break. Just hang tough LandYacht and work through the problems one at a time. Once you get them sorted out you will be proud of yourself and be able to count the money you are saving by not spending it on a new car of some description!

You'll get there!

Yup, expected I guess. I have a lot of parts on the way and many more ready for order. 200k will be a big overhaul time for this car.

I think the thing sat for a long, long time. And my everyday use probably revealed the issues. As they say, abuse it better than non-use.

All these things can be addressed.

One at a time in order of importance.

First, the factory original radiators (Behr) were known for their unreinforced upper hose necks, from the fsactory.

A new radiator at this many miles/years ought to fix the problem, even though the Behr's are now made in Pakistan not Germany I believe. A Nissens (Denmark) is the other alternative good choice.

Looks like the brake fluid is okay, but don't forget the manufacturer calls for it to be changed every couple of years - in the back of the "maintenance booklet" is where the stamps for these changes go - along for coolant too!

The nitrogen SLS spheres eventually need replacment, (I have done them twice now at 196k, so it is a consumable item). Careful, as all the fluid can slop out onto the garage floor in the removal process.




Might be a good time for an ATF fluid change, and after it's done install a new pan gasket, so that leak will be done with and corrercted and no more flaring, and loss of ATF fluid will plague you.

Your guesses about the tiny leak from "somewhere" are good guesses, and may be the source, but also, the 560 motor has a tendency to "seep" a bit, around the back of the driver's side valve cover asrea too. Worth a look....

I think these older cars like this can run a few years for virtually nothing, needed, then all of a sudden a whole lot of issues crop up at once.

To me, based on ownership of one of them, for about 18 years, it just goes with the territory.

You should be fine, the car sounds like it is essentially a good runner, just with some catching up for you to do.

Good luck...

Well all I can say is: Don't park that thing in MY driveway! Seriously, royal pain but they are old cars. I had to replace some of the SLS lines in the back of the car. Used off the shelf brake line. Regret it. Maybe I'll replace again with factory lines. Darn thing is still leaking. Blasted salt and such they use in Cincy rusts every thing. Had to replace two steel fuel lines a few months back. For water leaks, I like to presurize the cooling system to just about where the cap vents and then look for leaks. I usually find a bumnch of hose clamps that need tightening

My 85 300D which I parted and junked about 4 years ago was the oileyest beast I have ever seen. It leaked oil all over. So when I installed that engine in my 240D, I put on a new valve cover gasket and I removed the whole oil filter, cleaned up the old gasket area and put on a new gasket, and it is perfect. Can park it anywhere and all that great Mobil One stays in the engine and none is on the driveway!

What you are describing is simply the 'Fluid Replenishment Plan'....

All old cars eventually get signed up for it, kind of like AARP...
