Engine blown due to low oil - is it worth replacing?

My neighbor gave us their riding lawn mower when they moved, and so we enjoyed it last year. My son especially. No oil was added throughout the summer, and the engine is now toast.

Phil, depends on your ability and financial resources. Personally, I'd replace the engine since I am frugal:-)

"do it all the time. I take old lawn mowers, push behind & riding mowers and rebuild them. The problem most people face is what is called ""hydraulically locked"". What this means is that the engine gives all indications that it is seized up. What takes place is the carburetor has old gas in it and has sat for the winter. Then Spring comes along and you get on your mower you turn the key and it does not try to

start. It will not turn over as the flywheel cannot turn because it is hydraulically locked. What has happened is your seat and float do not seal properly and allows gas into the cylinder and floods the cylinder and the engine itself in the oil compartment with old gas. The best way to check this is to pull your spark plug and then turn the key. The engine will turn over and pump all the gas out of the cylinder. The next thing that needs to take place is that all the oil has to be drained a new oil put in plus you need to pull your carburetor off and thoroughly clean it with carburetor cleaner."

Some Lawn mower engines will seize pretty quickly on low oil, and that is actually a good thing. Before going beserk, on replacement, Try this first. First, fill the engine with oil to the right level, Next, remove the spark plug wire connection, and then the spark plug, then tip the lawn mower up to the spark plug hole is straight up. fill the spark plug hole with diesel, or some kind of penetrating oil, lubricant and let the mower sit for a while. I like a half hour. Next, with the lubricating fluid still in the piston hole, get hold of the mower blade (with gloves on) and start trying to move it back and forth. This may take some effort. If lubricant comes out the exhaust or carb, do your best to turn the blade to move the piston all the way down in the cylinder. Next, add more diesel or penetrating lubricant to the spark plug hole and give it another half hour. Then start rotating the Blade again and keep doing it, Lubricant will spill out, and it will be messy, so make sure plenty of rags and don’t do this where you don’t want lubricant on something. Next, to assure some top engine lubrication, mix up a batch of 2 cycle mix gas, but make the ratio 25 to 1 rather than 50 to 1, fill the gas tank, and shoot a shot of raw gas in the spark plug hole, put in the plug and work at starting the engine. Once you have it running, it will smoke a bit. Let it run the tank of fuel completely and then refill it with 25 to1 again and do it all again! I have done this approach for several engines and have only had one that was not recoverable!
