Hi All!

Need some advice. My M-E 114 engine failed under power. I was doing about 80 on the highway in 6th gear when there was a loud bang, then a lot of rattling and no power (sounded like a bunch of rocks banging around an oil drum). Towed it to the nearest HD dealer and as expected zero compression on one of the cylinders (rear).

They wanted my authorization for 4 hours of tear down time to determine the issue. I figure that $500 bucks is better spent on a new engine since I doubt this one is salvageable.

What do the rest of you think?

Thanks!

Possible broken valve spring, caused the valve to hit the piston which caused the loss of power, sounds like you need to authorize tear down instead of guessing

@KGB - based on other threads, even if it's just the valve spring and valve... would you have concerns about piston/cylinder damage and shrapnel floating around the rest of the engine?
