Recently replaced pcv valves with genuine OEM parts and changed spark plugs the other day which I noticed were quite oily.

The car still smokes, but not under boost or at idle all the time just very randomly like if I go for a drive them stop at some traffic lights I'll get a smelly plume of oily smoke bellow out for a second then stop.

 

I'm thinking of changing the valve cover gasket and the one below which is just sealant I believe?

If so would blue hylomar be a good choice?

At the same time I'm doing some water deletes and a fuel pump change, thinking I may aswell do the injectors too.

Would brand new OEM injectors be worth buying or any alternatives?

Might be valve stem oil seals, if you are getting oily plugs.

 

I used liguid gasket on my exh rockers, intake covers have a rubber gasket already, but check to make sure they are still supple enough and making a seal. A slither of sealant wont hurt on the intake covers.

 

As long as the injectors are in range 10-15 ohm then you could look at getting them sonically cleaned, cheaper than new, but if you want a longer term peace of mind then a few hundred quid will get some new ones.

Check for a price with MJP alternatively you could try the US routes.

I hope it's not valve stem oil seals they look like a complete pain in the arse and this is a low milage engine from zedworld a few years back.

Will try and source some injectors though, thanks.
