Upper Oil Pan Bolt Tightening Torque

1978 280CE: 123.053
Engine: M110.984

Does anyone happen to know the tightening torque on the M6 Cap Head Bolts that hold the Upper Oil Pan to the Engine Block? (Not the Bolts that hold the Lower Pan to the Upper Pan.)

Next question - Do the Upper Bolts require a Thread Locking Compound?

Appreciate any info!

MM

I don't wish to seem awkward but it does sound like you need to get a copy of the FSM - it is available for free via startekinfo.com (albeit a bit irritating to access at times - if you get stuck I'll send you a direct link)

Hi Stretch,


I've got both the FSM's for the Engine, and both the FSM's for the Body and Chassis. I found the tightening torques for the lower oil pan to upper pan, but for the life of me, couldn't find the upper pan to the block. Maybe I just need to look again, or maybe the torques for the lower to upper are the same as the upper to block.


First thing I religiously do whenever I buy any vehicle is shell out the bucks for the FSMs. Invaluable, I agree.


Regards,
Mark

EDIT - I'm looking at Section 01-310 Complete removal and installation of oil pan right now, Tightening torques. They mention Oil drain plug, Filter mounting bolts, and Oil pan lower section to upper section @ 11 Nm. There is no mention of Upper section to Block. Thus, my quest for the Upper pan bolts.

1000 apologies - I thought you might be going commando there!

https://www.startekinfo.com/StarTek/outside/12265/program/Engine/110/01-310.pdf

Oil pan lower section to upper section 11Nm
Oil pan 6 or 5.5 depending on the effing dipstick (whoever came up with that idea that is a dipstick!)

No sweat. The link you posted is exactly the page I am referencing. Still .... no mention of upper pan to block bolts! Only Oil pan lower section to upper section.



Isn't the Oil pan 6 or 5.5 referencing Oil capacity in Liters?

Looks like I'm the dipstick! In my defence I was trying to multi-task cooking dinner and typing doesn't mix...


...I'll keep looking for you.

I seem to remember this subject for the OM61X engines too.

There is this thread =>

Oil Pan Torque Specs For 1980 240D

Ignore the Haynes data (it is as usual not quite right)

I keep my Haynes in the WC, and I don't use it for reading!


I came across that same thread you linked, earlier today while searching. Post #13 (while for a 240D), mentions:
Upper Part of Oil Pan to Crankcase 10 Nm
Lower Part of Oil Pan to Upper Part 10 Nm
Since the bolts used on both upper and lower oil pans are M6s, we could cautiously assume they both get torqued the same.


Be careful multitasking .... you may end up frying your fish with 10W30 and filling the engine up with extra virgin olive oil!

...

I think it is a fairly safe assumption to make - the values in the Haynes are obviously way off

Very true - I'm not built for multi-tasking - it could indeed result in the ultimate peach parts oil thread (!)
