Has anyone hear removed the oil pan from their 300SDL? I need to as my pan is leaking and I want to have it patched. It has some sort of plate over the front of it with rivets going into it. Then it looks like they used epoxy around the edges, well now it's leaking. I also know my oan gasket is leaking so I'll get two leaks in one hit. The pan gasket is leaking enough to get to the ground though so that's good.

Have you removed the pan with the engine down on its mounts on the crossmember? I think the FSM says to raise the engine but I prefer not to as those huge allen bolts can be a pain for me to line up. I didn't know if it is perhaps possible to undo the pan then slide if forward then out? For those unaware, the 603 uses one large oil pan and costs $300+ new so a patch is the only route because I've never seen a person selling an oil pan for one of these. I'll be happy once it's done since it's a rather large leak. If the car is parked more than 5-10 minutes it leaves a spot. My rear crank seal is also leaving spots, but only about half as large however.

Thanks
David

are you talking about the steel lower oil pan or the large aluminum oil pan that covers the entire bottom of the motor?

The 603 is different from the 617 in that it just has one big pan. Well, it has a lateral pan that goes off to the side. It is one big aluminum pan.

Thanks

I don't have access to welding equipment so I need to remove the pan for the repair. I was hoping something like you said could be done.

Thanks
David

You have the perfect excuse now to pull the engine so removing the pan will be a breeze, and you will have the opportunity to do the rear seal. And while your at it, degrease the engine, do a new thermostat, water pump, stuff that is hard to get to installed.

I had the pan off my 603, but it was out of the car. Cant answer your main question, but you could try getting the pan off by lifting the engine and let us know if you were successful.

if i were in your place i would try to remove the patch and fix it wo removing the engine. the various epoxies and such are excellent and it it doesnt work you are no worse off than you are now. the key is getting it very clean.

I think it would be a pain to get it completly cleans because oil would constantly want to be running out. I think I'll just jack the engine up and go from there. We have a screw on a stand thing that we use at work to raise engines for such work. It is a tool that you use when working with a lift so I'll give it a shot within the next couple weeks then report back.

My engine has been degreased and is actually really clean. The bottom cover on my IP leaks some so that keeps getting dirty fast. Also, my lifter pump gasket is leaking, my hard fuel return line is leaking, my rear main is leaking, and my oil pan is leaking, also, it appears the oil pan gasket is leaking just barely so that will be fixed along with the oil pan. I think I'll also re-seal the lateral pan with the oil pan off. I hate looking out in front of my girlfriend's house and seeing my usual parking spot. My SD was also a terrible leaker, so her family has to be really turned off to MB diesels by now.

Thanks
David
