Rough vibration and exhaust sound

Hey guys, just after a little technical help;
I'll try to be as detailed as possible in the hope that someone out there can easily identify the issue.
The car has now picked up a pretty heavy vibration and very rough sounding idle. As per the video posted on facebook (https://www.facebook.com/matthew.mo...f_t=video_processed&notif_id=1471574495523951), the car starts normally and idles at the right RPM but a rough gurgling sound and a vibration that shakes the car quite vigorously now occurs. From the engine bay side of things nothing really sounds much different, just really noticeable from the exhaust end.
I have pretty limited knowledge of engine-related issues but would this be a missfire or just a cylinder dropped..?
The car drove fine earlier this morning, gave the car a wash then I noticed this problem on starting up again. I slowly attempted driving it hoping it would shortly come good (I didn't notice any major loss in power) but the car felt like it would vibrate itself to bits so i returned it home after a couple 100m.
Fiddling wires around the PTU and plugs made no difference.
Any help is appreciated.

 

Probably dropped a cylinder. Check your injector and coilpack connectors. Unplug each as the car runs and you should hear a change in note. If you don't that's your cylinder that has dropped out.

Clean your connectors and see how you go.

Spot on Chrispy, the top right cylinder (closest to battery) wasnt firing. I removed coilpack to find a shit load of oil and that the end of the coilpack was still stuck in there. My plan from here is to try remove the rubber boot stuck in there, put a working coilpack in and hope that all 6 cylinders will fire long enough to get the car up to Rob260 where i'll let him work his magic - seems likely to be a rocker cover leak. I did notice a little oil in another spark plug chamber and the plenum also.
