RT Smoke at startup...

[IWN2RYD]

:helpsmilie:pps:

Sooooo... I try not to worry about the small stuff. Weird things happen of and on. But this has become a more consistent "Thing".

We "Broke in" our RT-S SE5 by not going over 6000 RPM's (99% of the time) and babied her until about 670 iles on the odometer. Then we drove it as we normally would.

Ours seems to looooove 6200 RPMs and goes hard/strong through 8500RPMs when shifting or hard steep hills.

But what I have noticed (ours has it's own garage) is after say a 100 mile trip the day before... We get a blue ish puff of smoke out of the exhaust when I fire it up and pull it out. Not consistently mind you.

But a puff maybe every other time. Like a sign we used to get when we changed over from Leaded gas to Unleaded and failed to add the additive enough times to wear out our valve guides.

Thoughts? Do I need to worry or is this normal for this engine? Thanks! :thumbup:

Probably a little oil in your airbox and over night it seeps down toward the throttle bodies. My RS did thay till I put the evoluzione filter on it and my Expedition still does with the K&N oiled filter setup.

Ah!! Well duuuuh. No idea why that slipped my mind. I will look at that this weekend :2thumbs:

i thought the RTs didn't suffer from that problem like the RS.

i would guess a little blow by oil from the seals gets burned off when you first start it.

here is some reading on breaking in the engine (some agree some dont)

I broke in my 103 cu in Harley engine the 2nd link on a Dyno way and it works great...

bottom line don't think you can do much if its probably a super tiny minute amount of left over oil burning off in the pistons when you start it up...

And... blue smoke is oil, white is coolant. Black is a rich fuel condition.
