To make a long story short, I blew the one of the oil cooler lines off my 300SD yesterday. I have had the car 2 weeks, seems the former owner modified the oil cooler line with a coupling with a check valve that got stuck. I happened to be looking at the gauge when the oil pressure dropped. I was heading off the road when it shut down. No clunks, just like I turned the key off. I had the line repair and now the car starts and runs like it did before the lossing the oil. Anybody blown an oil line and survived?

An oil cooler hose rupture is often survivable. Keep an eye on the oil pressure gauge but I think you're in the clear. At worst you reduced engine life expectancy from 800K miles to 600K miles

Sixto

It sounds like you'll be fine. A couple of months ago I had an oil change disaster where I wound up running the engine for a short time with no oil pressure. Naturally I freaked out and posted about it, and others told me about their own horror stories, some of which seemed much worse than yours. Their engines were OK so I bet yours will be, too, especially since it doesn't sound like it was under a lot of load and you didn't hear anything unusual.

Thanks for the response makes me alot more confident in the motor. Glad to hear other have similar or worse Now to start knocking off the rest of the list: AC, brakes, rotors, shocks, radio ect. As you can see the motor and transmittion was all I bought the car for

With luck like yours there was absolutly no harm done. The chances of actually catching the oil pressure dropping off while driving are pretty long. The way you caught it pretty well means the engine was not even without lubrication at all. Others wish their episode had been like yours. A warning buzzer for this model for low oil pressure has been discussed many times. Just human nature not to catch the oil pressure dropping fast.
