Anyone know of any particular area to look out for when changing motor mounts that can cause a massive oil leak. I found out that a brittle hydraulic hose can snap easily when lifting the engine...I replaced a lot of old parts on my 95 wagon today...engine mounts, hydraulic hose, heater hoses under the battery compartment which was really rusty, replaced coolant,oil and hydraulic oil, and she ran great! except for the oil puddle und drips down the driveway. She is hot right now and down about a quart after a five mile drive...I did notice the white gasket ring on the oil filter cover was kinda melted but i will check that tomorrow.

Thanks for any thoughtful thoughts in advance.

I think you may have damaged the transmission oil line to the radiator or the engine oil cooler line.

Same mounts are oil filled .

The 2 above posters seem to have missed the important piece of information: Engine is a quart low after FIVE MILE DRIVE!

Since they run nearby, it's entirely possible that you've cut or damaged one of the oil cooler lines that run up under the front bumper. With a leak that big, it shouldn't be hard to find crawling under the car with a flashlight.

Rule out the oil filter o-ring, it is likely, easy and appears to be "melted".

Well I'll be!

After having changed the oil on this car at least twenty five times, it appears that somehow I over-tightened the oil filter cover thereby crushing the O-ring and causing a massive seepage the garage floor. Looking at the filter housing from above it looked as though the o-ring had melted and after removing the cover and tightening by hand with about a half a turn with the wrench the leaking is no more.

The nagging thought is "how come this never happened before?".

Am I ready for the looney bin?

P.S.

The wagon runs like new again with the new engine mounts!

Obviously, Galilei never met some of the people who post on the internet.

it's easy to over tighten the oil filter cover using that MB tool that completely covers the oil filter housing to torque it down. it is only 25Nm if I remember correctly?

Enjoy the wagon - I miss mine every day.

ejboyd; If you can't contribute to the topic, keep your snarky opinions to yourself.

You just said what I said re the oil cooler line. Did you even read the entire post?
