What oil have you run in it those 2-3 years of ownership and how often it was changed?
Why are you guessing about the SAE30 oil and that have never been changed or you're talking about the previous owner?

Most of the 3 years I've had it, it's been sitting in a junk pile, I only mowed like maybe 3 or 4 times with it before it blew up. I had put Rotella T4 15W40 in it, and apparently when I picked it up and got it running again, the oil came out of it looking like tar and there wasn't as much as there should be, https://bobistheoilguy.com/forums/t...t-small-engine-oil-change.128191/post-6475128
Good autopsy 
. Showed people to maintain their push mowers better. I always got a good 4 years from a trash picked mower. All of them were neglected when it came to OCI's. But, I did the OCI's more frequently, and extended their lives. I mean, 20oz of oil is cheap... Yes, they were rappin and blow by, but you find ways to keep em going. You're 1st mistake with that machine was trying to get it running after 3-4 years of 15W40 in it. And the level was too low. You should have topped it off with something, anything, vegetable oil even. Then hit it with starting fluid,,and give her a spin on the flywheel.

I figured whatever was wrong with it wasn't worth diagnosing and fixing, so I swapped a different motor o the deck, and threw this motor to the side, and a few weeks ago I finally got the motivation to pull the blade adapter off, luckily it came off with a pittman arm puller I had and I didn't have to brute force it with heat.
Sorry, my mistake.. Read the post wrong. Yeh, most trash picked machines are in the garbage from rich folks who don't wanna get their white collar hands full of engine oil. My bro-in-low is one of those. I live in a well off neighborhood ( not by choice...because the school district is awesome for my 13 yr old daughter. I hate all my neighbors...every one of them. I grew up in The Bronx ) Anyway, every Sept is bulk trash. There are at least 50 machines at the curb. Never bought a push mower yet. I can actually pick out the best ones if I get out there early enough !!! Just drive around for 30 minutes and I got a machine. Now, come April, another bulk pick up. 2 stage snow blowers all over the place...Hate rich people, but like their garbage
