So the plot thickens.....
These are the same plugs that were a little oily the other day...cleaned them up and put them back in.
Pulled them out again today...
looks a lot like rust to me
compare these to one from the Soarer
The orange plugs are BRK6EP's
cyl 1 on the left and 6 on the right
the plug from the soarer is a BKR6E
found my little high power torch so had a look down the plug holes, piston crowns are dry, and also have a slight brown/orange tinge, No sign of any oil in #5, they all match evenly.
So I am thinking that Duncan is correct in saying that it is a turbo seal, Causing my smokey exhaust
Doesnt explain the lack of comp in #5, but I may have muffed the test, there was a bit of crap around the #5 plug hole that may have caused the tester to leak
The car doesnt seem to use any water, but I havent owned it long enough to say for sure, the oil is about 400ks old and looks brand new, so I think that if it was rings the oil would be a lot darker
????
Any more ideas
