Re: 1 Cylinder misfire spark plug destroyed lpg

At the time, I removed the spark plug and disconnected the fuel injector to the bad cylinder to try to prevent more damage, and I drove it home on three cylinders. In this setup I heard the banging noise, but it didn't happen straight away. I thought the big ends would have been put under a lot of s...

Re: 1 Cylinder misfire spark plug destroyed lpg

Yes that is going to be my next step. I will get a helicoil kit to repair the broken thread, and do a compression test. I also remember hearing a thumping/banging noise that happened once every revolution. I think this is most likely to be caused by play/backlash in the big or little end bearings on...

Re: 1 Cylinder misfire spark plug destroyed lpg

By the way, watch my video of the inside of the cylinder, you can see it looks like the piston is pitted. I believe this suggested knocking. http://www.youtube.com/watch?v=yE3oejMPju0 This link explains the problems that can be caused by knocking/detonation: http://www.enginelogics.com/detonation.ht...

Re: 1 Cylinder misfire spark plug destroyed lpg

This is another forum I have posted on:

Their opinion is that LPG runs hotter and has worse cooling properties than petrol, combine this with the 3s-ge engine which runs quite hot anyway...

Re: 1 Cylinder misfire spark plug destroyed lpg

Thanks for the link volvobaggen, however that doesn't explain why both electrodes fell off. You can see in the images below that the centre electrode is also missing. Blobs of metal have also been melted to the ground electrode; this is not shown in the image by NGK. NGK show a clean spark plug wher...

Re: 1 Cylinder misfire spark plug destroyed lpg

Thanks for your replies.

This is disappointing, although I didn't use a torque wrench to install the plugs, I did follow the instructions that were given: "Turn the plug until you feel the thread bite, then do another quarter turn".

Can you explain why this would cause the electrodes to fall off?

Re: 1 Cylinder misfire spark plug destroyed lpg

I have used a boroscope to see inside the broken cylinder. A link to the video is below. Skip to 2.31min to see most of the damage to the cylinder wall.

1 Cylinder misfire spark plug destroyed lpg

I'm new to this site but would really appreciate some help in troubleshooting my engine problem on my Toyota Altezza RS200 running lpg. After driving the car on European motorways I noticed that one cylinder was not firing at all, because at idle, the car was vibrating quite badly. I removed all the...
