Oops, just reread the post. Smoke changed from white to blue.

Well, now that you mention it, lol... It's gonna be kinda really rare to see a pair of blown head gaskets on a new motor, assuming the builder used the right gaskets to begin with.

Who knows... Maybe it is.

Welcome back guys! The smoke changed from white to blue on the first page of this thread. :lol: :lol: :lol:

OBGMC:

No synthetic oil on break-in w/ moly ring's.... good to know, did not know that.

I was told that break-in on Moly Ring's should be gentle for seating purpose's.... is that not true??? Just go out & run the crap out of it??

I break mine in at the water box at about 6-7k. :shock: :lol:

Smoke
 

Years ago , the rings were not as good and it took time to break them in.
With the newer moly rings, I break it in like its going to be run. The rings seat quickly and the rest of the engine doesn't need any breakin if you run a roller cam. Flat tappets need a breakin by keeping the rpms up to prevent flattening a lobe. (Unless that has changed).

If the smoke does not clear up, and its not black smoke,, you should probly tear the motor down and check it, because something might not be right with the clearances and could cause some high dollar damage.. i hope it clears up, good luck...

If the smoke dont go away, Get MR. Machine Shop that built it to pay for it Or FIXXX it!!!
