Hi Everyone!
I was hopeing some of you other 240D drivers could give me some idea as to how long it takes your cars to get oil pressure from a cold start. Mine is freshly rebuilt now. New bearings, new oil pump, new liners and pistons, etc.
It seems to take FOREVER to get oil pressure from a cold start. Once it gets oil pressure the needle is against the peg maxed out at 3 bar, but 15 seconds to get there?
Thanks in advance for your input everyone!
Chris

My cold is no where near your cold but I also have never had times any where near 15 seconds. The longest time I noticed was after I R&R'ed my intermediate shaft. That was maybe 5 seconds.

Try reaching under the dash to the back of the instrument panel and bleeding out the air in the oil pressure line. I did this in my 220D and the pressure comes right up after maybe two seconds. All you have to do is crack that little 10mm pressure nut a tad to allow air out enough to put a tiny drop of oil on your finger then close it off.

Hi Phil!
So what you're saying is that I probably have pressure much sooner than the gauge is telling me. I LIKE IT!!!!!!! I will give your suggestion a try.
Thank You!
Chris

Two things:
For the process that Phil described, I assume he means to do it when the engine is running. Otherwise you might let in more air. Can someone chime in on this one?

Also, on some of our cars, there are two small rubber o-rings on the center post of the oil filter can. Without the o-rings (or with old ones), the oil leaks out of the oil filter canister overnight and takes a while to refill when you restart. You can find plenty of posts that discuss their location and size. I am not sure if your om616 has these, but I suspect it does.

Good Point!
My car has the older style filter housing with one central bolt that goes through the cover, then through the filter, and finally screws into the housing. It does not appear to have a place for any o-rings or seals on the threaded end of this bolt. It would have to leak between the threads on the bolt and the filter housing. I suppose that could be possible. Hmmm, you've given me something to think about and explore.
Thank You!

Yes, I did mean do the bleeding while the car is running. Just don't let it get up to operating temperature, that oil is HOT!

What year 240D do you have? Is it one of the W115 body types? then it would have the center bolt going through the filter can?

The later OM616 and OM617 have the rod press fit into the filter housing lid. on the end of the shaft are two "O" Rings. these keep the oil from leaking out of the housing.


As to what Phil mentioned, place a rag under the oil line fitting to catch any oil leakage.

Our 240 had a problem with the pressure getting to the gauge for about 10 sec. I replaced the 2 "O" Rings, and it comes right up now.

If you Oil Filter has that Tube attached to the center of the top Oil filter Housing Cap:
Autozone sells a Metric O-ring assortment made by Dorman for less than $8.
Dorman Metric 172 piece O-ring Value Pack #799-450
In it are 24 of the 6mmIDx10mmODx2mmW O-rings that you need for the bottom of the Oil Filter Stem: enough for 12 Oil Filter Changes if you use the same sized O-rings each time you change it.

On 617.952s you can substitute a 7mmx11mmx2mm in the upper groove on the Oil Filter Stem instead of the 6mmx10mmx2mm. If you do that you have enough O-rings for 24 O-ring changes. (This was suggested by another member and I did it and it works; since I bought the kit I do this on mine.)
