05 42''MTD 18.5 HP B&S Intec OHV White/Blue Smoke/oil in exhaust

I Have a 2005 mtd 42'' riding mower with a 18.5 b&s intec ohv engine that started to emit thick blue/white smoke occasionally. After a few bouts of this over a season the mower ended up sputtering and stalling out. Since then I tried to turn it over and it spat large amounts of oil from the exhaust pipe. Now it won't turn over at all when it tries to it sounds like metal on metal grinding. I tried to manually turn the head ''guess thats what it's called'' and it rotates to a point but never makes a full rotation as if something is blocking it. I'm looking to see if the engine is completely shot and if so is it rebuildable and worth the time/money to rebuild it. Any pointers that you all can give me to determine the exact issue would be helpful. I'm not a mechanic but I am technical so I'm sure I can follow directions. Thanks Darryl.

First check the oil and see if it is way over full and if so the fuel may be leaking by the needle and seat on the carburetor and overflowing into the engine crankcase, if it is over full you must drain all oil and remove the filter then install new 30 weight oil and filter, before trying anything else, after changing the oil turn it over again and see if it can make a complete revolution and if so you will then need to either install a new needle valve and seat or have one installed. If the dead stop it makes when you turn it over sounds like a hard clank it is probably a broken connecting rod. and i would be on the look out for a good used engine replacement

From the sounds of it, you've at least lost the rings in your engine. I'm not sure of the circumstances, but it almost sounds as if it had too much oil in it. These small engines lubricate themselves by throwing oil all over the inside of the engine, and if too much oil is in there, it won't throw it. They will also burn oil off if it gets into the cylinder from the level being too high. This would give you your bouts of blue smoke. The grinding noise that you describe may or may not be an issue, but here's something you need to try. First, make sure that the oil level is exactly as it's supposed to be. Then, remove the spark plug and see if you can get it to turn over. If the cylinder's full of oil, it won't compress, and it won't let it turn over with the spark plug in. Next, get a can of starting fluid, and spray it in the spark plug hole. Crank the engine over with no spark plug in it. Repeat the starting fluid, cranking cycle until you don't see any more oil coming out. Leave the spark plug out, and let it sit for a couple of days to evaporate. Clean out the plug or replace the plug in the meantime, and then reinstall and attempt to start. It'll probably smoke like crazy for the first 15 minutes, and then be fine after that. This is the number 3 problem I've found when repairing small engines; with #1 being flooded, and #2 being having water in the fuel. Leave a comment if you find that it won't move even if you remove the spark plug, and I can discuss more with you then about your options.

Overfill oil


Sounds like the engine is tired. Blue smoke is oil burning. Hard starting is oil on the spark plugs and/or low compression. This also can be due to someone adding too much oil.
Sometimes, the carburetor Needle valve hangs u pa bit and the Crank case oil gets mixed with gas so now the oil level is high. Too much oil in a motor is bad too, that would cause theblue smoke too.
