    Hey Peter, you are the only person i know on youtube that goes such in depth on Toyota engines, especially the legendary 4afe/7afe. Keep up the good work and i am looking forward to more videos!

    Hello I was watching your video and very interesting my problem is my vehicle has no check engine light I burn oil through the exhaust but nobody can tell me where the leak is coming from I need to get a leap down test done it doesn't blow smoke out the exhaust all the time mainly when I stop at a light or a stop sign and take off otherwise it runs great what should I do should I swap the engine do the compression leak down test and the compression test and then go from

      A recommendation for you. I do a compression test and if any cylinder has low pressure. That's how he fixes the cylinder.

    Dear Peter,
    Thanks you for your videos! They are really helping me understand my Matrix 1.8L
    I have a problem with a crank, no start after I replaced the intake vvt gear due to the rattle on cold start. I may have had the timing off, but when I was checking by hand/ratchet. I hit the valves with the piston. I then re-checked the timing using your other video and double checked TDC and orange chain links to make sure. I re-assembled and have crank, no start.
    I will do a compression check next to find them problem. Any advice? Could I have done that much damage by hand to the valve? The other thing is I do not hear the fuel pump priming when the key is turned to ignition, but the car will not start with starting fluid and there is spark, so it must be compression. Thanks!

      Hello and thanks for the comments.
      Measure piston and cylinder compression.
      Pressure must be more than 10 Bar in all cylinders. Watch my video.
      If the pressure is low, you need new piston rings.
      And video on compression test:

    Hey Peter. Maybe you can give me some ideas. I have a 2006 Pontiac Vibe , which has a 1.8-liter Toyota engine, that will crank but not start. The problem is cylinders 1, 2, and 3 have zero compression. What could be some of the causes. I am thinking maybe a blown head gasket. I bought the car in this condition. I notice it has a leaking water pump and is low on water. I also notice small amount of coolant in the oil. I think the previous owner ran it hot and warped the head.

    • @PeterFinnTheCarDoctor
      @PeterFinnTheCarDoctor  2 года назад

      You have a really, really bad bug now. You have to disassemble the machine and first check if the pistons are OK. Then check the valves. And the cover gasket. It already sounds like a complete piece of junk for a machine...Sorry, mate!

    How is it possible that broken valve in cylinder 3 was a reason for not having compression in cylinder 4 that was clearly on the side of the engine?

    • @PeterFinnTheCarDoctor
      @PeterFinnTheCarDoctor  7 лет назад

      The broken valve was in the same cylinder where was low compression. Sorry for wrong info.

      @@PeterFinnTheCarDoctor, That's not true, you demonstrated no compression in cylinder 1 and cylinder 2 had the hole.

      Yep I noticed that. The zero compression cylinder was furthest from the timing belt (so would usually be called cylinder 4), but the one with the damage was the second from the timing belt.

      The head needs a valve job. The valves are dirty, so they cannot close completely. This job requires a removal of the head and new head gasket when putting the head back to the engine.

  • @dopiaza2006
    @dopiaza2006 4 года назад

    You could have also done a cylinder leak test to see where the issue was before removing the head.
