ok i changed my plugs today on my NA and whilst i was looking at the intake i noticed a trail of Oil (pic attached) whats this mean?

 

Also when i took throttle body and part of manifold off, the 2nd half of throttle body that joins the block, had a thick layer of Oil with loads of crap stuck to it, like a sludge, not pile of it just a light covering. And more then shown in the pic at the throttle body. We are talking a dark brown sludge cant see no metal through.

 

Also look at the spark plug that is out of cylinder number 6 what would of cause that?

yes an NA and the intake is Standard.

 

One thing i did find is there is bracket that holds top pipe off air box to body and the plastic arm to bolt to car had snapped off leaving a whole about the size of a box of matches, but being mostly covered as it was still sitting on the arm (if that makes sense)

 

fixed it now by attaching the arm and its mount back over the hole

 

Only thing i can think of is its come from that pipe you see....thats a cam cover breather i think?!?

Plug is a bit worrying James' date=' I would check the compression on that pot. If the plug came out like that, something has impacted it (heat won't deform it)[/quote']

 

How the hell i check the compression :D lol

 

I thought id also just add, that performance is still just perfect hence why im puzzled.

I have a compression tester you can borrow. Do it here if you want Monkeyman :)

 

seeing as i aint got a clue what id do with it, if you did give it to me....at yours sounds like a plan! :p

 

Just drop me a PM mate if ya know when u might be free and we can give it a test.

 

Cheers

James AKA the man who took 4 hours to change spark plugs :D
