Car Forum / BMW Cars / April 2004Sump (oil pan) for E30 318is
Hello Group, A sudden loss of all oil in the engine, and an inability to retain oil after a re-fill, has revealed a crack in the aluminium sump (oil pan) at the bottom of the engine (in doubt caused by hitting a rock on a rough track). I should like to know how easy/difficult it will be to repair this. It looks like it should be possible to unbolt the sump from the engine block without shifting/lifting the engine. Is it? What are the chances of getting the sump repaired by welding? Ally welding is apparently a delicate matter... Or am I likely to be able to get a new or secondhand sump to replace it? I know there are not so many examples of the 318is with the M42 engine out there or in the scrapyards.Could it be that the part is the same as the much more common M40 engine in the E30? Thanks in advance any information and advice. Michael Anders I did this repair on my car after I bottomed out on the road. I have a 91 318is (e30M42). This car has upper and lower oil pans, if you have just broken the lower it will be a simpler job. I broke both upper and lower. I had to lift the engine and drop the front suspension slightly to do the upper pan. I found used parts on the internet. Let me know if you have questions.

I got it off yesterday without any problem and took it to an expert on aluminium welding. He wasn't sure he could fix it, so I'm still looking for a replacement part. My question: is this oil pan the same as on an M40 engine, 'cos if it is I should be able to find one easily. Regards, Michael Anders > What are the chances of getting the sump repaired by welding? Ally > welding is apparently a delicate matter... It's not that 'delicate' on a non stressed part like a sump. But might just cost as much as a new one.  Signature*A fine is a tax for doing wrong. A tax is a fine for doing well. Dave Plowman dave.sound@argonet.co.uk London SW 12 RIP Acorn In fact I just got it nicely welded by an acknowledged expert for the princely sum of 26 euros, popped it back on and filled 'er up with some quality oil. I'm now hoping that no permanent harm was done to the internals by the loss of oil. I can't really tell yet if the engine's noisier. For years now it's been sounding like a bucket of old nails when it starts from cold, and never was exactly quiet when well warmed up, though until now I've virtually never had to top up between oil changes (178,000 kms on the clock). Thanks to all those who took an active interest in my problem. I'll be driving 'er more carefully over rough roads in future.
