About six months ago I had the water pump replaced on my 95 E320. Now I
have droplets of oil of the floor of my garage. What can I look at under
the engine to tell if the oil pump is the culprit? I've pulled the plastic
cover off of the bottom of the engine and the oil *seems* to be coming from
the front lower left (when looking at the car) of the engine, but I cannot
pinpoint the source.
Engine's oil pump is inside the sump so this leak is not from the oil
With the engine OFF, I'd wipe off the power steering pump, including its
bottom, to see if it's the source; it's located left front - about where
you sense the leak.
Waterpump is behind fan...but as said...it's the WATER pump...so no oil
Could be many other places...if it's not obvious..have the engine steam
cleaned...then see where it's coming from
ooh and...pay attention to the color of the puddle...
steering fluid and trans ...red
no, there is not a direct connection
the waterpump just flansches into a depression of the motor block
have u checked valve cover gasket? that's a favorite place to leak on these
next would be chain tensioner..
sometimes it's just as simple as the oilpan drain plug or oilpan seal
is the hole engine covered in oil...or just the bottom...this would help the
process of elimination
whats the mileage?
many gift for x-mas
There 107K miles on the engine. Only the bottom of the engine is covered
with oil - no signs of oil anywhere on top (or anywhere that I can shine a
light from above). I checked the oil drain plug - it seems tight.

I'll ask the obvious question. How much oil are you seeing? Is it the oil
that's covering the bottom of the engine or is it dripping on the ground?
If dripping just how much? Also how much oil are you adding between oil
It's not dripping much oil - maybe less than 1/5 of a quart between 3K oil
changes. The oil seems to be accumlating under the oil pan (as well as some
on the lower hoses, etc. on the forward portion of the engine)m, dripping
onto the protective plastic cover, and then dripping to the ground.

This seems to be what most would consider a 'nuisance' leak AKA seepage.
There is a florescent dye that is put in the oil and illuminated with a UV
lamp that will show the source of the leak. I've seen this done but never
had the occasion to do it myself.
yes there is a gasket, but as said, this gasket seals water only! so forget
waterpump, if you habe an oil leak
places for well known OIL leaks come down to this:
1) oil drain plug
2) oil filter / filter housing
3) oil pan gasket
4) valve cover gasket
6) front crankshaft seal
7) rear crankshaft seal (transmission)
8) head gasket
9) if present, oil cooler and its circuit
10) happy x-mas
