Wanted to drain my 300CD block, as the coolant has been in there for a decade (Rotella ELC, came out beautiful BTW).
Followed the DIY, was very careful with removal of the drain bolt. All went really well until I went looking for the washer. Now, I was and am conscientious of the washer. I removed everything gingerly, things went smooth, nothing fell, but no washer. I’ve since checked the drain pan, the ground, etc.
I think it’s stuck to the block. But I can’t tell. Certainly the opening on the block seems high, but no attempt to remove what’s there carefully was successful... and the last thing I want to do is harm those threads.
So what do you think?
This is with the plug screwed back in. Seems to me that the washer must be there by the look of it. I’ve never drained the block before so I don’t know what really is the case here...
Opinions?? Thanks!
