Hi guys, just a update so I changed the spark plugs over and all good (or so I thought) misfire gone ran the car for ten mins and seemed fine, took the x for a spin round the block and no issues at all, so drive to work the next morning and half hour into the journey the judder/missfire is back!

So today while taking the rocker cover off i can see the rocker cover has been leaking in serveal places where the cover has dried u, when removing the cover in places I had to chip it off where it had dried up and gone hard.

Also noticed a lot of yellow mayo on the underside of the rocker cover above what would be the engine chain leading to the crankcase hose, inclipped the hose and it full of this yellow mayo stuff.

This crankcase hose is also split on the join, and came away while inspecting it. It full of this yellow mayo so wondering if something blocked, or maybe it been blocked because of the knackard rocker cover.

Where does this hose go, is it easy to change? How important is it, does it make much difference or cause any issues with it being split/having that split in it.

Thanks again Jon
