Can anyone save me some time - I will be removing the oil separator on my 93 245 tomorrow and want to have an O-ring ready in case it needs it.

Thanks,

Sorry to waste people's time - it was in the FAQ all along! - "Buy a replacement o-ring (it is listed as 34mm IDx3mm) for the box, since the existing ring is sure to be hardened"

Funny, I just referred someone there too. I love this site.

Ron,

Your post helped me.

I went to look for one to measure it for you, and came up empty-handed, so now I have it added to the want list. Works under the distributor on the 240, too.

Doing a thing wrong for a long period of time gives it the superficial appearance of being right.

What is an oil separator? and where is this monster in the 240?

The oil separator that the poster mentions is the "breather box". It is located on the driver side of the engine underneath the intake manifold and is black in color made of plastic, held in place with two bolts. Unfortunately, I do not know the size of the needed O-ring (smaller than a bread box, bigger than a wedding ring), but alas if the breather box is removed a new O-ring is required unless a serious oil leak is desired.

Replace every time eh? OK, I didn't last time and there is some oil there so I better have the part in hand before I start.

Thanks for the information, when should the breather box/oil separator
be replaced if ever?

It can clog up with oil sludge and lose effectiveness - less likely to clog if you use synthetic oil. Try blowing though your flame trap system with the oil filler cap off - not very scientific, but if there is lots of resistance you should probably take things apart and have a look. Check the 700/900 FAQ for a description and a warning.
