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?

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!

If the lifters have 100,000 miles, I would try to buy the same ones again . People on this site change them every 20,000-30,000 miles

Any of you guys ever stopped into Far Gohn Brewing Company in Culpeper, VA?  Steve is a very distant cousin of mine whom I’ve never met (but have exchanged emails with).  I plan on stopping in next time I’m on my way to Arlington.

I like a lot of dark beers, but I cannot handle that cloudy stuff unless it is a nice hefeweizen.

That cloudy stuff is worth it's weight in gold down here, my buddy who is a professional Beer Mule, makes some serious coin traveling up the east coast buying and bringing back 50+ cases of premium top rated beers from a list of top notch breweries and making 2x & 3x the cost of the beer

Yes, but havn't started it yet, still putting it back together !
Bearings look good, and no metal bits anywhere, very clean cam chest, and I believe the lifters were the originals !

Did you change the lifters? What about the cam bearings?
