Coils + plugsplugs

[Davyhoogy]

Just removed the spark plugs and coils.
Do these plugs looks ok? Quite a bit of oil on them. The oil looks like it's coming up out of the cylinder.

The coils are all very perished also, will this effect the starting much?

As the spark plugs go down through the centre of the rocker cover they have seals to keep the oil in. A leak from one of them seals would fill the spark plug hole

 

[Davyhoogy]

So a new valve cover possibly? That's beyond my mechanical knowledge

 

[Antm72]

Possibly the gasket is it a 6 cylinder ? Its only the rocker cover gasket its not too taxing if you can weild a spanner

 

[Davyhoogy]

Yeah 6 cylinder. I've had a look online it doesn't seem too hard.
I've changed thd plugs. Still stutters a few times before starting. So not sure on that issue

Could be cam sensor causing the stutter, worth reading codes.
And cracks in the air intake pipe work, seems to be a service item at this age.

The electrodes should be dry and a light brown.

Electrodes look good, was the plug in tight?

 

[Davyhoogy]

Yeah I think so. I've put new ones in anyway I'll check them after this tank of fuel
