    I'm loving all these informational teaching videos! Just got through watching a video where a guy was telling people to put oil on the backside before installing, claiming the oil would squeeze out. I thought it sounded like bad advice. I rebuilt my first engine back in 1985 when I was 19 (a 455 Super Duty big block in a 78 Trans Am). I learned then to not lube the back side. Glad you confirmed this and explained the reasoning.

    Seeing a spin bearing as a mechanic is like hitting jackpot, but as an owner operator I imagine it must suck, great vids josh

    It's refreshing to hear someone actually call it an engine and not motor!

    Luckily no losses in this dept. In March '16, I had engine inframed due to failed rings. Then in July '16, I had rod and main bearings replaced. Having well in excess of one-million miles, I hadn't noticed just how low the oil pressure had become. After the bearings replacement, oil pressure jumped from 40-psi to 62-psi. In 2017, I had the bull-gear and other gears on front of engine replaced. This year 2018, I'm going to have six-pack injector replacement and see if it's possible to get a new high performance camshaft installed. I've spent a lot of money to ensure my engine lasts for another million or two miles because I like this particular engine and the truck it's installed in and I want to get all the life out of them as I can without the detrimental issues described in this video. I'm very pro-active when it comes to maintenance including oil changes at every 15,000-miles religiously.

    Great video! Shocked I didn’t hear him mention oil starvation. You can do normal maintenance and change oil regularly every 3k miles but still spin a bearing. In my case at 148k miles my engine was burning oil worse than I knew. Didn’t leak oil at all. Saw oil pressure light come on, checked oil and no oil registering on the stick. Ticking started soon after and then a few months later came the rod knock. Pulled engine and confirmed spun rod bearing on cylinder #1. Most engines will start burning some oil after 100k. I suggest you regularly check your oil level even if you know your oil should be good for another 2k miles.

    extremely helpful. Spun a crank bearing on a 3126b last week after coming out of reputable shop and running for only 183 miles with 90k on motor and good maintenance. Coincidence, destiny i don't know but this helped me understand what i'm dealing with. Thanks

    The best explanation I heard. Currently dealing with main bearing damages to the crank, it’s painful. Thanks

    Thanks for sharing your video. Always appreciate Knowledge Based Video with visual examples. Would like to see the other damaged components, i.e., Piston Rods, Thrust Bearings, Damaged Bent Valves, Broken Blocks, Cams, etc..

    My BMW X5M with 49,000 miles unfortunately had a rod bearing spun. The oil was changed religiously every 5,000 miles & I drove like a gentleman. Dealer wants $36,000 for a new engine & will not offer any assistance. Decided to have it rebuilt at a fraction of what the “stealer-ship” wants. The rebuilder, who used to work for BMW, said that they designed the bearings to be too tight & this is a common issue with low mile BMW’s

    I worked as a Toyota tech in the 90s. The 1-HDT engine had an issue with rod bearings but would usually give no warning before throwing the rod out of the block.
