What's inside a Million Mile Engine?
Thanks to Keeps for sponsoring this video! Head to keeps.com/b2b to get 50% off your first order of hair loss treatment.
Ever wonder what makes and engine reliable? Why have manufacturers like Toyota and Honda have really reliable engines while some others don't? how come companies like BMW can make some engines that are really reliable and some engines that don't make it 100,000 miles? in this episode of Bumper 2 Bumper we take a look at what engines, that have proven to be reliable, have in common, why not every modern engine is built that way, and happens when you put the most reliable aspects we can find into 1 engine. Is your engine on our list of reliable motors? You'll have to watch to find out.

    He is wrong , the Offenhauser Indy Car engines had no head gasket. Head was integral.

    “We measure an engine’s lifespan in Miles, becouse that’s the only metric we have.” You mean that we measure an engine’s lifespan in 1.6Km?

    Well, everybody knows engine oil lubricates, but that's not how it cools by reducing friction, allot of people overlook that it's a very important part in cooling too, since engine oil is in the combustion chamber area, it's in direct contact with the hottest parts of an engine, it cools by transferring heat away from components, and accounts for up to 40 % of heat removal.

    Well, I don't have one of those "untouched" engines because I like to tinker. I go through my 68 Corolla's engine every 250-300K miles whether it needs it or not. It was 20 years old when I bought it for $300 and ran fine but no idea what the actual miles were. I had never touched a car engine before beyond maintenance. I bought a Haynes manual. Best $12 I ever spent. One day I was out runnin the back roads and the crankshaft pulley bolt broke off, key was lost. Found a guy with a welder nearby and just had him weld the pulley in place. Well dang, can't find another crankshaft but I found a 1200 short block. Basically the exact same engine but 3/16 - 1/8 inch taller deck and stroke. So it's been 1200 instead of 1100 for the last 15 years. Bonus!...putting an 1100 head on a 1200 block puts it closer to 10-1 instead of 9-1 compression. riprip. I've rebuilt the entire car at one time or another, mostly because I'm mean to it...even making one good transmission out of two with different problems. One just wore out, the other had the shaft get bent when a u-joint broke. Broke the case too. Good guts though. Perfect synchros. I make my own cables for it, clutch is cable operated, throttleIt's been a lot of fun. 2 door,1600ish lbs, 75-80 hp, 4 speed, 4:22 rear. It's limited slip but the slip is so limited it acts like a posi. It's even got 2-60 A/C It's due for a little love and paint now.

    !.9tdi easily over 300,000 miles ???? I've had 3x 1.9tdi and if ridden well and with respect they can reach easy a million miles. I have driven 1,2 million km with these 3 cars and never changed a water pump. Never had a real engine problem These 90's engines were / are bulletproof and vastly better than the modern complex junk engines with their gigantic carbon pollution. And easy to repair. With verry cheap cost for the parts (Nederland)

  • BryceLovesTech

    That's pretty simple pretty much anything reliable is Honda or Toyota. Anything unreliable is built by FCA Chrysler or BMW

    whats better letting the engine warm up or driving is right away?

    I've got two vehicles that are pretty reliable. 1991 Jeep Cherokee: 4.0L I6: over 378,000 miles. And 1987 Ford F-250: 6.9 IDI V8: almost 700,000 miles. Neither of these vehicles have had engine rebuilds or replacements.

    My 1.8 silver top ford zetec is running super strong after 24 years and 217Mm (that's not much but the commutes are shorter around here), not a single oil leak or rebuild in that time. One timing belt change. Good oil and some care is all it takes.

    1 million mile engines: Older diesel Mercedes Benz motors, Lexus 1ufz series engines LS400/430, Honda motors, Toyota motors, older Chevy and Ford V8s. All great engines.

  • shonuffisthemaster

    good video although i have a correction to make, older engines (like early 1900's) sometimes did not have a seperate block and head / head gasket, all the assembly of the valve train was done from the crank case. granted, the design of the valve train was significantly different from modern engines.

    8:40 bandaids must be sterile. When they are not you can get an infection by trying to cover whatever wound you might have. Manufacturers put them in sealed packages to ensure that there isn't anything growing on it after they have sterilized it and sold it; its a guarantee that you won't get an infection if you put it on. As with all packages, they can begin to develop leaks and much like a food expiry date, that date is when the manuf. is like hey, there might be some nasties in there now, I wouldn't use it.

    What's inside a million mile engine? The same stuff that is inside all other engines apparently. A better title for this episode may have been something like, "What it takes for an engine to make it to a million miles." A lot of us really want to see what is really inside a million mile engine now.
