After parking my car today I noticed a trail of drips leading to my parking spot. Further inspection reveled that the angle "thing" that supports the rear of the oil pan (a 240D feature only I think) has worn a hole in my oil pan. Just 2 days after I started using this car as a daily driver and got rid of my ford too.

I plan to pull the angle 'thing' and the pan and weld the hole up. Should I just leave the angle 'thing' off?



At least I caught it when I did and didn't run it dry!

Wow, I hope you had already disaasembled that some, otherwise thats a pretty bad looking mount. That angle thing used to be an engine mount of sorts. It was an angled tab bolted to the frame, with a rubber grommet on it, that used to fit into a bracket assy that mounted to the two bolt ears cast in the aluminum pan nearby the mount (pointing down) If that is the condition you found it in, that certainly explains the friction hole. I can get you a pic of what it should look like if you need. I would look at the other engine mounts to be sure they are ok, as that tab should have been adjusted away from the pan (it has a slide adjust).

I just removed mine from the crossmember before I installed the engine.

That's about how I found it. Never thought about it being an engine mount. It never did have the bracket part which could explain why I didn't know what it was. Other engine mounts are new, I replaced them when I put in the engine about 4 months ago. I don't think the 617.950 even has the provisions for properly mounting it. This could be why I had so much trouble getting the new engine aligned.

I got the bracket and pan off. There was a perfect rectangular dent/crack in it. I couldn't get the thing sealed up very well with my crummy little 115 wire feed welder and my sub par welding skills so I shelled out $100 to overnight a new pan and gasket.

Next best thing to welding (in some cases) is epoxy putty. My rear muffler is on it's 3rd life for $10.00 The stuff is amazing cures under water, sticks to anything, is strong and can be shaped and painted. A must have for the emergency kit!

If it was hitting the pan it might have been what you were fighting against for sure, and would possibly explain how it got against there since you never knew. The two main mounts are really the supporting members of the engine, this third small mount I think was more of another aid for vibration dampening than anything else. If you want to replace it or see what it used to be origionally I can still get you a pic. Too bad the engine I'm running now had a crushed oil pan from its former life crash, otherwise I'd have had a spare for you. Had to put the pan and pickup tube on this one from my old 616 engine.

My Dad's old '81 300D is cruising around somewhere still with a cracked oilpan fixed with JB Weld - I had to perform an emergency repair after driving it too fast one night when I wasn't supposed to be driving it at all. Anyway it held just fine forever.

Long story......

I fixed a 300 W198 motor (Gullwing) cast iron oil pan with JB Weld. It got water in it from sitting outside without a head for say 30 years and froze / cracked. We used the parts engine on a spin-tron machine where the engine (good head) was spun up to around 9000 RPM and a strobe was used in each cylinder to view the valve timing.
