91 350SDL -- oil in the intake manifold

I found that there is a lot of engine oil droplets coming into the intake manifold...and think it must be bad oil seals in the turbo.

I am working through 350SDL issues and found the solid hose broken that goes between the air intake (pressure side) and the mechanical accuator that opens the waste-gate. I am assuming that this has caused the previous drivers to drive it over-pressured. Would that impact the turbo oil seals so that they could now be leaking into the intake air? Are there other things I should check knowing this has happened?

1982 300SD engine mounts question

I see the engine mounts from under the hood. I also noticed what looks like a mini-shock absorber. Is that part of the engine mount? Is it important? How can you tell if it is working? The engine vibrates while in idle but it has no effect on that mini-strut. The rubber mounts are soaked in engine oil but they are not torn. I'm not sure how old they are since I just got the car 1 month or two ago. Mercedes Source has a neat engine mount kit that I can buy but I was wondering if aside form the two rubber engine mounts and the transmission mount, if the mini-strut should be replaced?

1984 300SD ATF level drops when cooled ??

According to the manual, the ATF level should be 5 mm below the low mark on dipstick when at air temperature. I imaging this is because hydraulic fluids expand when heated and contract when cooled. I have the opposite: my level is at the full mark at operating temp, then rises about 2 inches over full mark after it sits overnight. It's as if the torque converter is draining into the pan overnight. The transmission is fine and doesn't leak.

Anyone have any thoughts on this? Thanx.

91 350SDL -- HELP - dropped something into engine

This is a new car to me and I was replacing the glow plugs. To make it easier I removed the Intake Manifold on that engine since some of them did not have the 'proper' nuts on the bad glow plugs.

My mistake was to not cover the intake holes and I think something fell into....ALL THE WAY into the cylinder (past the valve). I have all the nuts and bolts that I was using, so I can't figure out what fell in. After I put it together I heard a metallic bang, bang, bang when I started the engine so I shut it down right a way.
