Blue smoke at the end of dyno pull At the end of my third and final consecutive dyno pull yesterday (club dyno day) I noticed some blue smoke start around 5.5K or so. Here's a vid, but youll need the latest quicktime:

What do you guys think? Could it just be the oil thinning out from three consecutive runs? Car runs fine and oil presure is great. The smoke was not present on the first two pulls, except for a little black smoke on decel. I just hope my rings arent done...
Thanks,

well maybe since you did the head swap not to long ago there are some fluids in some tight places and its just burning it off at that high RPM. did u spill anything when you did the swap??

On the inside of the motor? Not likely. I did however blow off my exhust the night before the dyno, and i had shimmed the band clamps using aluminum tape so theyd bite a little harder. It could have been some of the glue from the tape burning, but im fairly certain it was oil. Ill check the plugs next weekend. Might also be carbon from the headers blowing out. I dont do a lot of WOT blasts, so three dyno pulls in a row could have broken up the carbon a bit. I guess time will tell. Id probably be heading a cracked ringland if that were the case, no?
