I have a Cub Cadet rider with 16.5Hp Briggs. I was mowing the other day and the engine slowed down and then puffed smoke then died. Will not crank now seams like it has seized up for some reason. It has plunty of oil for i check it before I mow everytime. Does anyone have any Idea why this happened and do you think a rebuild is worth while?

With no pics and no details, we can not help with the should you rebuild question accurately.
Engines that end in 1/2 hp (16 1/2) are usually LT's not GT's, and are usually disposed of!! :dunno:

Well I konw that I was mowing for about half hour before it happend. I checked the oil after and it was black and thick. I tried to rotate the motor by hand it moved about quarter of a turn then made a metal on metal sound. So i assumed it was seized. I hope that helps. Let me know what other info you need and I will post Thank you

HUH! Not familiar with that engine on that machine...but yeah engines to go for time to time. I guess it's the nature of the beast.
My advice and that's if the engine is gone and you're generally pleased with the mower is to just remove and replace it.
I know you didn't really want to hear that mdeshon but with today's new math mostly that's the less expensive alternative unless you personally want to dig in and replace a $12 broken push rod or whatever.

A rod most likely went, not a $12 push rod. Open it up to see just what it is.But from what you said she is most likely history.:sorry1:
Metal-on-metal is bad. Very bad.
Do you have a compression tester and air compressor? That will tell you just about all you need to know regarding the health of the engine.

I would do a differential compression test. If you need a "how to" on this, just let me know and I'll walk you through it.
The results of the test will point to a problem with a valve, rings, piston or conrod. From there you'll know if you are just removing the head or splitting the case.

If it will only turn 1/4 of a turn how is he going to do a compression test? Sounds to me like it puked a rod or dropped a valve. Anyway something important that makes it go broke.:sorry1:

I understood it as 1/4 turn and he heard a metallic noise. If it flat-out stopped turning, then something significant is broken. Remove the head too see if you dropped a valve. If the head is in good shape, split the case to inspect the crank, conrod and main bearing.
Hi mdeshon, the easiest way to verify serious engine breakage is to remove the sparkplug, & insert a long skinny screwdriver or stiff wire (15"long), insert until the wire finds the top of the piston, then try rotating your flywheel by hand, reverse rotate or whatever you need to do...watch the wire or screwdriver for any movement caused by the piston. Busted rod can quickly be foundout like that, by trying to follow the piston with the wire, as you rotate the flywheel.
Metal to metal contact, could just as easily be an external engine/accessory problem, could you please report that the piston is going up & down?

As blurry as that is, it dosn't look good (Recommend either macro mode on the camera for close up's, or holding the parts futher away) the stove buners are cristle clear :fing32:
As said above, Pull the engine. Place in the shop and disassemble, this will be the easiest way to see what is wrong, and determine if it can be fixed or needs replaced.
Engine codes will be needed to research parts.
