Took out the plugs out of the 6, about 30000km (18750 miles) since last plug change. The plugs are NGK Iridium (BKR6EIX).

Took some picture of the plugs, found oil on the thread (as highlighted on 1st pic).

Pic 2 and 3 shows the condition of the sparky bit. Not too sure is it good or bad, looks like it all burnt up. Any comments? Thanks.

Don't look too bad to me.

Is it not running very well?

Smile Not problem with the engine, always run smoothly.

I know from the last plug change, the older plugs (Beru) all have some oil on the thread, just thought I take these out and have a look and found the same.

Juat wonder if there is anything wrong?

Looks fine, it's if the plastic shrowd around the base there isn't a sort of light beige colour that you might have an issue.

There is a lot of black crap on there though, is it fuelling properly?

Not too sure about fuel problem, always filled up shell vpower or sometimes BP ultimate. 98 octane only.

I notice the black intake barrel is bit rusty and oil/grease all over it. Also I always found the inside of intake hose connecting the barrel to throttle body, is always oily. always give that area a good clean up every couple of months. Could it be running to rich?

It's a ceramic insulator, I don't think anything plastic would last long on a spark plug Laugh

But the plugs look fine, as long as the build-up on them is dry and not oily.

Yeah, it's a combustion chamber so it's not going to be nice and shiney after all this time. LOL
