Great video. Well put together.so much good info in 6 minutes. I wish i could get that training

great comment I also am a great believer in secondary ignition analysis. But with a lot of the new coil on plugs and in some cases inaccessible coil-on-plug I'm not getting the patterns I used to. In this case we're going to use this to measure the duration relative to each other each cam lobe in intake and exhaust and we're going to look at variation variation in CAM intake cam lobe is caused by slack timing chains so you great comment thanks its great talking to a real technician

Firing order is incorrect and also is the vacuum pulses identification however using the right firing order and the proper pulses identification it is the #2 the one with low vacuum . Note: correct firing order 1-5-3-6-2-4 And correct vacuum ID from sync on #4 firing event 3-6-2-4-1-5

Great video but you know if you know how to read a ignition scope you can see a worn camshaft just by looking the scope don't need to use the first look you just need a good scope like say the Pico scope

Do you have a video on how to read ignition scope

Good information but isn’t that actually cylinder 6 intake pull? cylinder you shift over 3 from tdc? 360 degrees to the right.

You are correct, it is our error

So if less air was being drawn into the cylinder because of that lobe would it also mean slightly lower compression? If so would a pressure transducer on that cylinder show less compression pressure than the others?

@willispeek3846 7 жыл бұрын

Low compression will reduce the amplitude, but this valve reaches the apex of the cam lobe too soon. Each valve should reach the apex of the cam every 120 degrees of crank rotation. This valve reaches the apex of the lobe and turns before the other cylinders as measured by crank degrees. A bad lifted would also have a lower amplitude but it would not change the timing of the cam lobe apex.

@willispeek3846 7 жыл бұрын

Yes, less air is entering, you need to measure 720 degrees to determine the apex is being reached too soon. In cylinder testing is for a single cylinder and it takes longer than looking at the intake and exhaust. It takes time to learn how to analyze the complex waveform. But I do engine running and cranking. Cranking shows me the pumping action without combustion when I disable fuel. I still have spark to identify cylinders.

@Aaronsmith467 7 жыл бұрын

Oh I see what you are saying. I guess the manifold vacuum test is also preferred because the engine is running with the fault occurring uninterrupted as opposed to removing the spark for the pressure transducer test. Efficiency is key. Thanks for the reply!

@willispeek3846 7 жыл бұрын

Yes, it will require developing the skill to understand the patterns, but it is quick, efficient and accurate. it also gives you the reference of all the cylinders. In cylinder testing is great for final pin pointing the exact cause of the problem because you know it is going to be productive.

i found same problem with a snap throttle compression test,but i like this method cause it shows lobe appex
