Is 350 Break In?

[blackfiddy]

i recently purchased a black IS 350 i was wondering if you guys have an tips on breaking the car in. also when u guys turn your car off do you hear any sounds from the engine. like popcorns being made under the hood somewhere.

Break it in per the owners manual. Don't make hard stops for 100 miles and drive at varying speeds for the first 600 or so miles.

Haven't heard of anyone with the popcorn sound. You should have that checked at the dealer.

lol!!! i think the popcorn sound is from the engine cooling down after using it. every car does that. I dont think he means like while hes turning off the car, but as he exits the car, you will definately hear something if the car has been on for 5 minutes or more. Its more like a ticking sound than popcorn really. :P Also, for hte first 5,000 miles, do not accel too fast, do not brake too fast, do not do anything stupid at all. lol. i think that sums it up

Well, the heat shields on the cats may go tink tink tink, but I never heard them go poppity pop pop.
