Oil in spark plug wells jtd 20v multijet

I have a 156 jtd 20v mj she has oil in the wells were the spark plugs are (know very little about cars) have drawn out the oil with a syringe and will monitor to try and identify we're it's coming from. Im a plumbing and heating engineer so have a fairly practical mind lol. Any ideas ? Thanks chaps have pic but not sure how to post (newbie).

Can you post some pictures? Your car doesn't have spark plugs or wells. Do you mean the injectors? (5 big things on top of engine where spark plugs would be on a petrol)

Are you sure its oil? It can be blow-by deposits (carbon-gunk) if your injector seals have had it.

Diesels have glow plugs, not spark plugs, .. could this be where the oil is collecting?

Glow plugs are down the back, the injectors are those 5 things stuck right into the top of your engine, connected to pipework..

Injector seals are pennies, but it can be a mission to get the injectors out of the cylinder heads sometimes, due to corrosion.

1.9 jtd 8v engine is not very fussy. Just make sure you change the oil regularly, I do mine every 6000 miles (2.4 10v - same engine just 1 more cylinder). I use Valvoline Maxlife 10W40, same as what we use in Twinsparks. Selenia 20K will be fine as long as its 10W40.

Four posts, all asking the same question...!!
So, same answer again:
Selenia 20K is not suitable for a JTD engine.

Why don't you just use the correct spec oil.
It doesn't have to be Selenia/Petronas, it just needs to meet the required spec.

Have you looked at the specs for "20K" ?

You say it has never worked better, but what were you using before...?

The Valvoline Maxlife 10W40 that Pud refers to above has ACEA B4 approval, which makes it suitable for a JTD. 20K doesn't.
