190E 2.3-16v Oil Pump
A while back a chain rail fell of and clogged up the oil intake for a good long while (the car was driven no where while this was going on). In the diagnosis of that I replaced the oil pressure gauge, the pressure relief valve at the exit among other things. I just tripped out to Indiana for school (Purdue University) and about 200-miles out my oil pressure started acting up. Before the trip my oil pressure was always at 3 above idle, i know that for a 16v it should be at 3 at idle as well (thats not critical, but the more robust oil pump of the 16v keeps it there). So I figured that the oil pump was damaged when the chain rail fell off and clogged up the intake. Now, however, I have some bigger problems. With a cold car the oil pressure will still hit 3 bar, but a warm engine at idle will go down to below 1bar and close to 0! I know .3 bar should be acceptable, but something is obviously broken and its getting worse so it needs to be fixed.
I think there could only be one of 2things wrong right now and I need some help. The oil pump could be worn out and needs to be replaced, or the other pressure relief valve is gone. Its probably the oil pump. I do not have my repair manual out here with me, but I will get one. I just would like to know what I am getting into and what is involved with replacing the oil pump. What needs to come off and how much of a pain in the ass is it? Thanks, Jim

i am not familiar with the 16v engine, but most benz pumps i think can be removed through the lower oil pan if they have one. does your car have the low sump with a removable bottom?

I know the oil pan is removable, thats how the oil intake was cleaned. I am not sure how it was done as at the time I simply could not figure out what was wrong so I sent it to my mech (the best in the state of CT) and he figured it out pretty quick. I would rather not have to do that again because he is not free and I am perfectly capable of doing most things myself.
Thanks, Jim

The oil pump on the 2.3 engines was part of the front engine cover...takes a well trained MB technition about 12 hrs to replace the COMPLETE front cover.
Removal of the oil pan is part of that job....
