    Hey guys picked up my cat on Friday. Drove it home following break in procedure. I have under 400kms and on start up it is blowing blue smoke from the exhaust. There have been a few other members who have mentioned there cat does the same thing. Trying to figure out if something is wrong or if this is normal for the hellcat engine. Thanks

    Mine did not when I first bought it, although I had a brand new Supercharged Jaguar in 2009 and it was very smokey on start up for a couple weeks the. It went away but always used a bit of oil, like 1 quart for every 5000 miles but other than that it ran great and put 198k miles on it before I traded it in.

    Mine does it too. I meant to ask that question on this site too and forgot about. I guess the grin it puts on my face every time I take off made me forget.

    My mechanic said it may be valve seals.

    Probably needs some time for the piston rings to break in, The blower puts a lot of stress on the pistons & rings.

    No smoke ever here with my 15 charger HC. I do see the black carbon crud and water but that's pretty normal. My GMC does it some and my wife's ecoboost does it really bad

    None here. 1/2 quart used by first oil change (1800 miles) but nothing since. All good!

    At first I thought since it has forged Pistons, maybe they needed time to warm up and expand to get a better seal. Usually forged Pistons have a looser tolerance to give room for expansion, at that point the pistons and rings seal to the cylinder walls giving maximum performance. Maybe that's just my old school way of thinking, but that's the way they use to be done.
