Re: [MBZ] Low Oil Pressure W124 2.5 Turbo Diesel
Should be about the same -- the reason you normally see 2 bar is that the cooling spray jets that spray oil onto the bottom of the pistons open at 2 bar. Unless you have a really worn engine or a dying oil pump, there is enough flow to open the jets at idle.

Verify that the pressure is indeed low and you don't just have a bad pressure sender unit! Mine did something similar, then dropped to zero and sat there. Replaced the sender, works fine. It is also possible to dislodge an internal seal in the oil filter, which will drop the oil pressure quite a bit.

Cold engine oil was full but indication of mix with dirty oil, so not a clean drain and fill. SO, my take is that the transmission will need some work and there is a problem with oil flow. No obvious burning or blow by out the tail pipe. Or leaks around the engine seals.

Re: [MBZ] Low Oil Pressure
The real issues are the transmission having an over-broad neutral. Nylon bushings? Checked cold ATF and it was over full. After the test drive, with engine running, stick was dry. Normal, for low fluid. Needs more ATF. Oil pressure indicator does not peg. Light off, got pressure close to 3 bar. Sender/gauge can also lie, should be checked. What am I missing? $2300? Don't forget the other SL vulnerabilities. Rust, primarily. ATF and shifter bushings is nothing, if that's it. ACC/Cruise may be broken. How are the sunvisors? Surprisingly expensive, and the sun eats them. Chromed plastic trim pieces on seats? Upholstery? Rear window defroster may be failing, the hairline wires in the glass fail easily. This car is down in the just drive it class, rather than a garage queen. We'll probably be driving past that car tomorrow, we're on our way to Crystal Mtn.

Re: [MBZ] Low oil pressure?
The Westerbeke oil pressure reads: Start up diesel 65 psi 20 minutes operation 30 to 40 psi and drop to 20 psi a few times at 2200 rpm Throttle back psi go up to 50 to 55 then drops down to the 30 to 40 psi range Change oil sender and unit two years ago and no problem for that year. Last year oil pressure varied like above...he check sender and unit and said it's seems O.K. resistance ...

Re: [MBZ] Low oil pressure?
Worn bearings will not make the pressure fluctuate up and down. Bad wiring on an electric gauge will. Flaky bypass/relief valve could too. If the pressure rises when you decrease RPMs, I would wonder about oil level not being ideal.
Re: [MBZ] Low oil pressure?
Bill - I guess you have checked the easy stuff. O-rings on the oil filter bolt, proper filter, proper oil viscosity? It is also pretty easy to drop the steel portion of the oil pan to see if there is loose stuff in there that may be being sucked into and blocking the the oil pump inlet screen. Case in point, when I dropped the pan on my SD to replace the turbo return line grommet, I found some old bits of gasket, from a previous repair, stuck to the oil screen. I don't think the bearing wear is so much a factor of age as the total miles. Especially if the oil has been changed regularly.

Re: [MBZ] Low oil pressure?
How low? Is it above 1 BAR? If so then it is not low. Another cause for low oil pressure is using a Fram oil filter. Fram uses 2 paper elements instead of a paper on the top section a mat element on the bottom section. The lower mat element is the bypass filter with an incorrectly manufactured filter, too much oil will pass through the bypass, dropping your oil pressure.

Low oil pressure after it gets up to operating temps? #1 cause is bad main bearings; or perhaps a bad pressure regulating valve on the oil pump output combined with a worn out oil pump combined with the wrong oil viscosity.
