Hello and welcome to Just Answer

If there's oil around the injectors, its well worth checking that this is not in fact fuel.

as if you have a leaking injector or a cracked feed pipe then this will result in the injector pressure being lowered ( = misfire) and also leaving fuel over the top of the engine

If the EGR valve is stuck open then this too can effect starting so try disconnecting it to see if this helps or changes anything
Could also be an injector leaking fuel back through the overspill pipe, so not getting enough fuel pressure to tell ECU to fire the injectors, this is trickier to find and you’ll need the garage to do a ‘run back’ test to identify which one is the issue
you can also do a reasonable run-back test yourself by disconnecting the electrical plug on the injectors and the downstream pipe of the leak off, crank the engine over and if you see a noticable difference if the flow in the leak off then that the likely problem injector.
Lastly it’s also worth considering fitting a new fuel filter as if only slightly blocked this can lower fuel supply pressure and choke the main pump, the pump will be more sensitive to this when its cold as diesel thickens considerably with low temperatures.
It may have developed an air leak on the fuel supply

Thank you for your response but it’s definitely engine oil around the injectors and head thanks again Andy

Hello Andy

OK in that case the most likely source of an oil leak on the cam cover is from around the injectors where they pass through the cover and from the cam cover gasket to the head

so its best to remove the cover and clean it thoroughly and use some silicone sealent to bond the new gasket to the cover before re-fitting

also check the seal on the turbo oil feed pipe

Hi Matt A leak to first gasket you mentioned wouldn’t cause a misfire would it but would a problem with the oil feed to the turbo make it stop running or fire on one two at most
