      I've bought old falcon sixes for $500 before. Let's do the maths. It normally costs say $100 per oil change (I do them myself) every 5000kms. So over 50000kms, that's $1000. If one $500 intech last 50000kms on one oil change, that's a lot cheaper.

In my time i have seen some vehicles do 500000 thousand ks and some others with 800000 all because of oil changer on time and not abusing the engine in general Thumb up bud keep up the good work

      Toyotas are the most dull boring cars & I don't personally like them. My nephew had a 90's camry (>250K miles). He only did the brakes the first time a few years ago, changed out plugs wire & belts the first time at the same time. The parts he pulled off it were factory parts. Absolutely solid car. No rust, decent paint, good interior, everything still worked. I was impressed.

    Years ago, I was waiting for a phone call to start a new job. It came suddenly one afternoon. I started the next day as a mechanic with a hire boat company. A private boat had stopped the day before with a minor engine problem. The company boss had gone to take a look, had started the engine, a 4 cylinder diesel, had revved it up and 5 seconds later the oil pressure dropped to zero. I went on board and started the engine which ran smoothly but with still no oil pressure. I looked around the engine and discovered cracks on the right side of the block. When I took off the rocker cover, the rear two sets of tappets were completely loose. After taking the engine to bits, I discovered the camshaft had broken into 3 parts and a conrod had broken and shattered the block. All due to revving up a cold engine. Ended up fitting a new engine in the boat.

    Well explained John. As a keep ‘em till they die guy my tips are; pick a vehicle with a long production run drive train, preferably with an enthusiast community. Bonus points if you can go post CAD but pre Finite Element Analysis.
    Change your oil at least every 10000 km, half that if it’s all short trips. Go up a grade in oil viscosity, i.e instead of 5w30 go 10w40.

    There is an effect that used to be called acceptable quality. The idea is you only produce a quality that people will accept whether it be manufacturing service industry and even journalism the problem being is as the acceptable quality becomes the norm people will then start to accept a slightly lower quality and it ends up in a downward spiral of quality until you get to where we are now. Hopefully we are at or near the dregs of the barrel and people will start demanding better quality but the climb back up will be slower than the slide down

Recently I quit smoking and had some car trouble so I thought I'd have a go at it to keep me busy. Quick self research found out I'll fucking die if use the supplied jack. Back to research and figured I could spend $300 on not dying and another $100 on making things easier, but it's capital expenditure so should be wife safe. Since then I've fixed a vacuum leak, changed various hoses, ignition coils and cables, sparks (and learned how to check gap), break pads, speed sensor (that was a c) and am about to do the cooling system.

    Your comments about knock are pretty good really. Maximum cylinder pressure doesn't happen at TDC, it's more like 14-18 ATDC, I figured it would be 90 ATDC because of the lever arm, but that would mean that the piston would need to be directly above the crank throw. But the crank/rod angle wouldn't be right for maximum torque since the rod will be at it's maximum angle instead of straight up. So 14-18 ATDC is the target for maximum cylinder pressure.
    The ignition timing for maximum power is after the point of knock, but it will also destroy the piston, so the OPTIMAL timing is bouncing off knock sensor as you describe. Maximum power is temporary, optimal power is optimal.

    using what you said earlier in the video, roughly the ignition is advanced to a set amount to generate maximum power, if that's correct, preignition, knocking, detonation, whatever, won't generate maximum power aka lose performance, even in an old carby distributor engine.

      Detonation is when the combustion flame front exceeds the speed of sound. Instead of a burn that heats the combustion chamber evenly, it literally explodes and sends a shock wave to the top of the piston. It doesn’t matter where the piston is. It will bash everything to death if it happens often.
      Preignition is when the ignition happens so that peak pressure occurs before top dead centre and tries to make the engine run backwards. That would be a different kind of wrong

      Only really an issue if you have a car with a GPF (gasoline particulate filter). They require low sulphur fuel, which is only guaranteed with 95 and 98 RON fuels in Australia. 91 and E10 can be up to 150ppm sulphur which can severely reduce the life of the GPF.

    To be a tad pedantic.
    99% of detonation events happen after combustion is initiated by the spark.
    Pre-ignition is combustion starting before the spark.
    They are usually two separate mechanisms.
    Both are symptoms of other underlaying issues.

    • @jimarcher3711
      @jimarcher3711 หลายเดือนก่อน

      To add more tech bollocks;
      Detonation does not cause overheating, the overheating causes the detonation.
      This can be seen by EGTs dropping when detonation occurs. The energy that would normally progressively heat and expand the gases is instead converted into noise and mechanical violence, any expansion occuring too quickly, and at the wrong crank angle, to be harnessed.
      That said, best power requires low level detonation to be occuring, else combustion is not making the most of the available energy.

      Some quick math here: E10 is 10% (1 out of 10) ethanol, so if ethanol had a heat energy content of 0 btu it would reduce power by 10%, requiring you to add fuel to compensate -- ergo lower milage (assuming the load doesn't change). The problem with your concern is that ethanol does indeed contain somewhat more than 0 btu when it amounts to 10% of the mixture and it is added mostly for other reasons (not gonna argue over whether those reasons are worthwhile, but i'll note that I run E15 in my direct injection engine in an attempt to keep the intake valve clean when I don't run "Top Tier" fuel with that additive mix of cleaners).

      Dwell was the amount of time the points were closed for. Smaller points gap meant a greater dwell angle which enabled the coil to charge for longer in order to produce a stronger spark.
      Widening the points gap reduces dwell but it does advance ignition timing due to the points being open a fraction sooner. That's more a side effect than a timing adjustment.

A piston cannot decide it will move back up at a slower rate because its power stroke has been spent. Which is what our dude seems to say.

    The storage tanks were demolished and the steel was incinerated to remove all traces, highly toxic.
