Hi,

If you have 0 compression, it sounds like the cam timing chain for that side has broken or jumped time. If it was driven that way, that would likely lead to interference between the pistons and valves leading to bent valves.

With the spark plugs removed, take a light and shine into the cylinder to see if there is any evidence of the tops of the pistons being hit.

Let me know.

No, the full story went through how this happened. I pulled out the coil packs and the engine started shaking which I think made the chain fall off because as soon as I pulled them out the car came to a stop and didn’t turn back on instantly literally pulled coil packs out and in 3 seconds or less it switched off.

I’ll buy a tool to look inside and let you know tomorrow what it looks like.

Hi,

I will look for your response. I'm hoping that isn't what happened, but if there is no compression, something has to be stuck open or a hole in the top of one of the pistons.

Regardless, I'll keep my fingers crossed for you.

Take care,

Joe
