BX1800 burning oil and poor HP

[Leejohn]

If you trade it in I might be interested in it. I'm not to far from you. What year is it?

To make that engine right, with the amount of heat it generated..........about the only thing salvageable is the block. Maybe the crankshaft if you can get it turned and get oversized bearings.

I dissagree. I'm sure the camshaft, connecting rods, timing components, & most of the valvetrain are also salvageable. Also, when a crankshaft is turned, the journals are machined smaller, so you would use undersize bearings to maintain the correct oil clearances.

If you're not loosing coolant at this time, I wouldn't expect more than a standard rebuild to be necessary.

Actually, when an engine gets too hot, clearances shrink. Here's the problem with that. When you've got a piston that's the same size as the cylinder instead of a few thousands smaller, you get wear. "Rings" don't really get shot. What happens is that the cylinders usually get out of round making it so that the rings can't seal correctly.
I don't want to say "toss parts at it" though. Run a compression test on the engine. It should be as simple as turning the engine over with the starter (fuel shut off) with a compression tester in the glow plug hole. You'll spend some time with this, but that will give you a good idea as to the overall condition of the cylinders. Once you have tested it, put a few squirts of oil in each cylinder. If the compression comes up dramatically, there is a ring sealing issue. Keep us posted!!!

When an engine gets that hot the rings loose all the tension. If the rings don't have tension they are shot.

I wouldn't take that engine if it was given to me. It will turn in to a money pit

To the OP how did it ever get that hot with out noticing smoke or steem or smells.

What is non-interference combustion chamber, never heard of that before..

Such engines were used at one time in a lot of foreign cars. They had mandatory timing belt replacement miles to prevent engine damage if the belt broke. Also I think the Chrysler Corporation used them in some vehicles. Basically the engine valve train has to be in perfect time or the valves will open as the piston nears top-dead center and will impact the piston causing damage to the valve train and piston because of the lack of clearance between the piston top and valves when in the open position.

I was wondering the same thing. I've never heard of the 710 cap melting without flames! Ouch that must have been something.

I'll bet that pit will be nowhere near as deep as the amount that they will deduct from the tractor on a trade-in. That's assuming they don't hide some of it in the new tractor.

Nothing an engine swap wouldn't cure, eh?

 

[like2wheel]

That would be the best solution.

If you could find a suitable donor

It is a 2002 BX1800D 4x4 with 1348 hours. It also has a RCK60B22BX 60 inch belly mower. I bought it used in July 2010.
