    After inserting anything threaded, I like to start by turning it counterclockwise to feel it find the start of the thread, then turn it clockwise. That way you won’t cross-thread it while tightening.

    I would have to use my inch lb torque wrench my foot lb torque wrench only goes down to 25 ft lbs and that would be 11 ft lbs and i use a short piece of rubber hose to install spark plugs in any engine ,thank you for such a comprehensive explanation of this service, i hope people listen and follow your instructions and they too will be able to install spark plugs properly.

    The turn past snug plus a certain number of degrees only applies to new crush washers. If for some reason you need to remove and reinstall a plug use the torque spec. The term crush is a bit of a misnomer as the washer isn't totally crushed. This allows it to act as a spring seal and lock washer for the differing temperatures and metal expansion rares of the steel plug and aluminum head.

      Good to hear you must change your oil before the recommended/specified intervals. In my opinion going 6000 miles between oil changes is very destructive pretty small working engines. I try to not go more than 3,000 miles and I've been wrenching for 50+ years ..and I think there's a big difference putting in an extra 1-2000 miles additional contaminated oil. Of course nowdays unreputable car manufacturers have engines w bad Blow- by right out of the factory. I wish the mechanic would talk about the history of being various engines that, even new areoil burner /Bad blow by problems

    I am not sure if Peter said it but rule number one is to install/uninstall spark plugs on a cold engine, or maybe slightly warm, but never hot, that's because the head this days is made of aluminum and aluminum is a material that with increased temperature gets gummy so it's a high risk of stripping the head threads when torquing the plugs on a hot engine.

  • @MarianA-vu8tb
    @MarianA-vu8tb 17 дней назад

    Regarding whether to use anti-seize or not: most spark plugs these days will come pre-coated with zinc (acts as anti-seize), the tell-tell sign is looking at the color if they are shinny silvery color then they are coated, if they are any other darker color than it's safe to assume u need to put anti-seize, u should follow the plug manufacturer recommendation, if u so happen to have the not coated type it will say on the plug's website/spec sheet/box to use anti-seize.
    Also the zinc coating is supposed to last for the 1st installation only, should u take them out later on u might wanna put anti-seize if u're gonna re-install them.
    Never ever use regular copper anti-seize on spark plug threads, because of the high temperature u should use either a paste that's specifically made for spark plugs or use ceramic anti-seize paste, same thing u would also use for other high temp applications such as oxygen sensor threads, glow plug threads etc., regular anti-seize paste in high temp applications will cook and transform into seize paste 😂

    14:02 Make sure to pull the torque wrench from the exact middle of the grip area. That's where it's calibrated from. See tests by John Cadogan.

    • @Paul.V.24
      @Paul.V.24 Год назад +1

      If it's click type yes. If it's digital, and the transducer that would be measures the torque is in the head, or the wrench doesn't use a ratio of torques to give a reading, the it doesn't matter where you hold it. John also states this, I think.

  • @billsimpson604
    @billsimpson604 Год назад +3

    When using a click type torque wrench, and even with one of very expensive digital ones like Peter is using, many people make the mistake of tightening too fast, so that they exceed the set torque by quite a bit. Some people keep pulling on the wrench after it clicks or beeps. You want to avoid that. Peter is doing it correctly by using slow, even pressure until it beeps. Fortunately, on cars and trucks being in a hurry tightening seldom causes problems. The rather wide torque range they specify proves that. Head bolts are the ones you need to do exactly as the manufacturer specifies. Also the main bearing bolts, and the connecting rod cap bolts. Even in lawnmowers, you want those to be right, so they don't unscrew after a few hours. Not only do you have vibration to consider, but they get hot and cold repeatedly.
    Torque wrenches make good Christmas presents for DIY folks who don't have any. I bought a cheap set on Amazon. That is good enough, since I'm not working on airliners or rocket engines. After the SpaceX Starship had to be blown up in Texas a few months ago, the FAA told them that some bolts needed to be tightened more, or made larger, to prevent leaks.

    I noticed you didn't put anything on the threads. In your experience is it important to install the spark plugs dry? I thought you would want to add a bit of anti seize to the threads.

    • @slalomking
      @slalomking Год назад

      No anti seize on plugs. The threads are lubricated by a coating. I used anti seize a couple of times and it was very hard to get the plugs out. I left then in 120k miles as per the manual. Now I have done them at 120, 240 on two Toyotas with no anti seize after the 120k interval. They came out great at 240k.

    A tip is not to use any sort of wobble extension or connection. It can change the torque applied.

    • @MarianA-vu8tb
      @MarianA-vu8tb 17 дней назад +1

      Nope, it doesn't. What u said it only applies to impact guns, be they electric or pneumatic.
      When torquing manually like Peter does in this video using wobbly joints will not affect the torque number.
      The reason why it happens is because when impacting having wobbly joints will absorb some of the impact energy (will behave like a torsional spring) whereas when torquing manually you are keeping constant pressure so even if it flexes it will not change the torque number.
      When using impact gun the maximum torque you will get by using only the socket, any additions such as extensions, wobbly joints etc will reduce the output torque, and for max torque try using impact sockets, they are heavier than regular sockets, all those jolts are like hammer blows, the heavier the hammer the better the results.

    • @TheStpeteboy
      @TheStpeteboy 17 дней назад

      @MarianA-vu8tb Nope your still wrong! Even manually torquing a spark plug,the most accurate way to apply torque is with a socket or wrench with the least amount of extension. A wobbly extension could cause an odd angle so inadvertently you could over or under torque a bolt especially in a newbie. There's a reason why pro techs do not use wobble extension or wobbly sockets to torque down for example a head bolt.

    • @MarianA-vu8tb
      @MarianA-vu8tb 17 дней назад

      @@TheStpeteboy generally speaking yes u are right about the angle aspect potentially changing the torque number, but going back to this particular instance it should not matter, the wobbly joint is inside the spark plug tube so due to tight space it cannot create any significant angle, should the wobbly joint be on the other side of the extension between the ratchet and extension then yes you could easily make significant angles and mess up your numbers, but yes in my previous comment I omitted altogether the angle aspect.

      @TheStpeteboy 17 дней назад

      @@MarianA-vu8tb Thanks this was from personal experience many years ago. I actually cracked a spark plug using a wobble in a V6 Nissan engine because of the angle aspect. The " feel" of how tight a bolt should be comes from experience. Just making a point for newbies to minimize using wobblies if possible because it could cause an easy job to become a bad one. In this case, its a 4 cylinder straight shot no wobbly extension or socket needed.

    I'm having confusion torquing the soft gaskets that use inch-pounds. I've done the valve cover on my 97 Tacoma and transmission filter for a 2014 Scion xB, and same issue. As you go around all the bolts, the torque reading keeps changing back down to below specs. I became worried that if I keep going around and tighten to specs I'll destroy the soft gasket. There must be some proper procedure for this I'm not aware of?

    I alway blow out the sp plug hole -Before- i unscrew the plug. I also take a small strip of terry cloth rag and wrap it around the tip of some long tweezers. I carefully the conical shaped terry cloth into the spark plug thread area and turn gingerly this cleans a fair amount of carbon out of the threads. That way I make sure there's no debris or other things to goof up the torque. All you mechanics out there you know how one little grain of sand can cause a lot of problems with fine threads. Anyone out there have any experience with using a Crush Washer twice. I like to read my plugs about every 25,000 MI. I've heard that once you unload the Crush Washer that is just a seat properly when reinstalling the spark plugs.. something about the crush play not being able to properly 're- conform' to the conical shape of the spark plug seat. I don't know where that would screw up ability to get a proper torque. After many many spark plug changes I don't think I've noticed a fouling issue after doing this occasional inspection and re-install'. I heard and if you do this you should have a spare set of crush washers frankly i hv never replace the washers alone. Frankly I doubt my local napa carry such a part anymore... with all the modern inventory reductions, Not like the good old days when they had a lot of those small parts...... any opinions?
