My car is the Speed3 and runs great or it was. I recently had my timing chain replaced and it was running great. Been 2 weeks since the repair. Today coming home from work and exiting the interstate I was in 5th shifted down into 4th then 3rd. When I came to a stop behind traffic the engine died. I restarted it and smoke came from under hood. Wouldn’t start so I had to push it over. Waited 15 minutes as tried many times just waring battery down. After 15-20 minutes I tried to start and it started but loud clanking coming from the engine. Stopped and checked oil. It was dry! Got oil replaced (5 1/2 qts). and started. OK to start but clanking sound is still there. On hook to the garage. There was no oil light or anything. Just got done running 70+ mph on interstate for 12 miles no problem. Any thoughts would be nice. Thanks. ---

No oil in engine @ 70 MPH = Fried Engine. Tester ---

Yup, Tester’s right. My guess is that you spun a bearing. But that’s just the big news. The little news is that the other bearings are probably all damaged too. And perhaps the cylinder walls. Should I go on? Someone’s going to have to tear this motor open and do some serious work. Allow me a question: how often do you check your oil? ---

You say you got the oil ‘replaced’. Was this a fill until registering on the dip stick, or draining what was left, then filling with fresh? If you needed to add 5-1/2 quarts to read right on the dipstick, then sorry, but this engine is done. ---

The engine is probably severely damaged and will need to be replaced. But that assessment is not 100% certain until a mechanic does a few tests to rule out less serious problems first. So have those tests done. Still, you should probably anticipate looking at a rather significant expense to get this car back on the road.
