What is a spun bearing? Can you drive on a spun bearing? You can have a spun rod bearing or a spun crank bearing and when they fail, it sometimes destroys the engine like in our Lemons BMW. In this video I show you how to diagnose a spun bearing and possible causes. We disassembled the entire engine, every single nut and bolt, so you guys can see what causes an engine to throw a connecting rod and fail.

A common question in the comments is how can we have a junkyard engine and still be below the $500 limit and here is the answer: The goal of the 24hrs of Lemons is to try to level the playing field by having a bunch of junk cars race. This is the most affordable wheel to wheel racing in the world. Since our engine blew at our first race and we are putting in an equally junky 140k mile junkyard M54 engine which is what came stock with our car, the replacement engine does not count towards the budget. The new seals we installed to stop the oil leaks ($60) and the chain tensioner we installed ($6) does count and the headers ($100) definitely count but we were at $340 after selling everything we could from the car… So now we are at our $500 budget. I need to see if I can sell the cats because those are $400 but something tells me that we can’t haha. With that said, safety stuff does not count towards the $500 budget. Otherwise it’s impossible to race because the fire suppression system alone cost more than $500 and the cage cost $3800. Parts to make the car faster or perform better do count, but not stuff to save the drivers life. Now the “backup engine” is a good opportunity for a collab with another automotive KZfaqr who wanted to get involved and is trying to grow his channel. We aren’t using the backup engine unless ours blows up again which I can’t imagine will happen (knock on wood). So that engine won’t count towards the budget because it’s not in the car at the start of the race. If we end up having to swap it in at the track, it still won’t count because the time it takes to swap it in will make it so we are not competitive anymore. The next race we would have to remove it and put in another junk engine or take penalty laps. Lmk if you have any more questions about the $500 budget. Again, the main goal is to prevent people dumping money into a car and have an unfair advantage because they have a bunch of money.

Yeah it makes a big difference if you dont hear the sound and are in racemode so you might think the engine sounds good while its self destructing :) The car could have had very worn bearings from the start and if you buy a car and it sounds OK to you, there might be better condition cars that youve never experienced that could be the "normal condition" ones ;) My volvo 850 has some sound that feels like crank bearing knock but it still takes top speed runs and sounds normal when very warm. I'll let that old heap explode when or if it does :D It sounds "ok" and "normal for an old car" but if I compare it to my parents volvo with same engine thats been rebuilt few years ago its a night and day difference.

I think it's important to also remember that oil gets really thin on the track. I actually would not use the factory recommended oil in this car. I'd consider going up to a 10w60 oil. I also recommend a product called Motorkote. I've been using it for years and it really does work. You can check out Project Farm's video on it, it will seriously save an engine in that kind of environment from being cooked. Even if it is a 240k mile worn out hoopty lol. I watched a friend run his chevy small block around the track for almost 20 minutes without realizing it didn't have oil in it (his oil pressure gauge stopped working). The only explanation we could come up with was that the Motorkote saved the engine

I think you should've also considered an overheated oil situation. Obviously oil gets thinner the hotter it gets and during prolonged race conditions it can reach temperatures of 130°C and more, which normal oils just aren't designed for. Also the warm oil weight (in your case 40) is measured at operating temperature (90-100°C), which is significantly lower than what you're gonna achieve on track. It means that you're actually getting thinner oil than you may have initially thought. To conclude i would personally run at least a 5W-50 oil, coupled with an oil cooler or at least oil temperature and pressure gauges to keep things in check in the future. Best wishes in the next race, love the content Chris!

I can confirm oil temps definitely affect the pressure. I run a pressure gauge on my dash and I’ve ran the car hot before at 220 (still in oem specs) but the oil was definitely hotter and oil pressure at idle was siting nearly 10psi lower than when coolant is at 180. I do have a factory oil heat exchanger that uses coolant but doesn’t help if the coolant is running at 220. Still made 75psi at higher rpm but definitely shows how real oil temps can affect its performance. Also that certain oils flash point really affect how well it holds up to heat. I’ve found liqui moly endures high heat a lot better than rotella t6 or castrol edge. For daily driving like a normal person, the “oil is oil” makes sense, but driving hard will separate the characteristics of different oils pretty well.

One thing people in general should know is that "low oil pressure light" actually means "not enough oil pressure to even idle safely" (fuel pressure is not a fixed amount, it rises as rpms rise because the engine needs more oil in high rpms). When you get a low oil pressure light, immediately shut off the car. It will spin a bearing and do this quicker than you realize.

@michaelkrenzer3296 2 жыл бұрын

This why a lot of experienced Lemons teams have a seperate oil pressure sender set for a hot run or hot oil pressure...usually attached to GIANT trailer indicator light on the dash right in front of of the steering wheel. Drivers cannot be trusted to look at guages but a blinding light right in their field of view is hard to miss. Another is a coolant pressure light. In practice once up to temp the coolant system should be at at least 4 PSI and if it is, light is off. Second it drips below, light comes on. This is important because boiling coolant is still going to show about 212f on a temp guage which is a totally fine racing temp even as it is all boiling right out of the cooling system until you are totally dry.

Its value as far as the judges are conserned is 0. Replacing the same engine doesnt count against you. What could count are the upgrades hes doing to the replacement engine. but they arent actually in the car at the moment. In theory you could endlessly upgrade your car at the end of every race as long as it doesnt exceed 500.00 some of these teams race 4-5 times a year for the past 10 years.. they may look like crap.. but they are surprisingly well engineered by thier teams.

@serhanozdeger8877 2 жыл бұрын

Hi Chris, nice video ! I'm sure you already know some of these but as a former engine bearing expert, I would suggest couple of things to overcome this situation. It may be true that engine was badly maintained before the race, however it can encounter the same destiny within a short period in race conditions with standard bearings. It is very likely that coating is completely worn out in that con-rod, oil clearance is increased and thus oil pressure is dropped. 1) So high of a rpm for a long time, such as an endurance race, cannot be handled well by a babbitt coated bearing. This coating is very very soft and will wear out quickly even if you replace them with brand new ones. Babbitt coatings also start to detoriate after 180 C, which is very likely to happen during an endurance race. I can see that damaged bearings' brand is Glyco. I'm pretty sure that there is appropriate replacement bearings which are "sputtered". In this case upper con-rod bearings will be coated with much harder material, which will wear out much slower and will handle most of the beating coming from pistons. In this case, lower bearings should still be babbitt coated to embed all the dirt coming from oil with soft layer. 2) Consider using polymer coating ,preferably on top of sputter coating. This will enhance the emergency lubrication properties of the bearing surface especially for short periods of oil starvation (such as cornering etc.). Polymer coatings basically provide dry lubrication properties when there is not enough oil. Extra thickness that comes from polymer coating should be considered in terms of oil clearance ! 3) For race cars, oil clearance should be adjusted slightly higher than a normal street car. Otherwise, at high pressures during race, oil will be squeezed out of the bearing, leaving the bearing less than ideal oil amount.

Do you recommend adding additives like LiquiMoly Ceratec to the engine oil?

@aravindsankaranaorist Жыл бұрын

Your take was very helpful. I am a novice bearing engineer (hydraulic actuator bearings). I was wondering, does higher rpm require higher oil pressure to ensure oil film??. Also does changing the oil clearance require a change in oil pump/system change from stock??. Thanks!

Anyway, I’ve never forgotten that night, and as a kid then I would have frequent nightmares, thankfully I got the help I needed but I never wanted to drive a car.
