Ok, all you shade-tree mechanics, what is "your" break-in period and when can I try out the red-zone???

I broke mine in the same as my Cobra R. Drive it to the track, check all the fluids, heat up the tires, and Drop the Hammer. Currently got 19000 miles and not one problem. Fixed an intermintent clutch release bearing squeal myself by winning the burnout contest at a local Ford show. Noise hasn't returned since that day. Tire wear seems to be my only issue. Been looking at all this worry about engine noise. I don't have it. When the noise causes the slippery stuff to run out the side its time to worry.

I was told to do the same thing...drive it
hard from the start to seat the piston rings
properly. All it states in the owner's manual
is to vary speed. Well, racing is pretty
good for doing that!

Yeah, there is no babying these beasts. Drive it like you stole it right outta the dealer. The main thing is to vary the engine speed (rpm's) throughout the whole band...that includes up to the redline.

One thing is make sure you let the oil warm up. It takes longer than you think usually a couple high miles. I wish they would have out an temp gauge in this thing.

I have been told about the oil warm up
too. Good thing that by the time I get
to the local drag strip about 45 minutes
has passed.

hmmmm, interesting, how do you seat rings when the cylinder walls have a cross hatch scored in the wall and the ring is a smooth ring? the ring cannot grove into a cross hatch pattern.
if i buy a new car and drive it off the lot, it sure better not be smoking out the tailpipe indicating rings not seating.

Hey Bobistheoilguy,
That's interesting. I am not a mech. Maybe
the mech I asked didn't know about the
cross hatching when I asked him about break
in period. Are all cylinders cross hatched?
So what you are saying is they are already
seated? Curious. Thanks for the info!
Another thing my mech friend told me was that
motors today have much closer tolerances as
far as parts fitting together than say 20
to 30 years ago.
