I was doing some reading last night and happened to come across kevin landers webpage again. I found some useful info under the tech section on breaking in new motors. It turns out that a rough idle is gonna occur during the first 1000 miles of ythe motor's life, also that I had to change teh oil at 500 mi and then again at 2000 mi. Well we kinda drove past teh 500 mi mark on the way home from maryland with the car. So first thing this morning I went and bought some oil and a filter for it.

I changed the oil and noted that the old oil was still pretty new looking. Anyways, I starte dit up and let it idle for a maybe an hour. It stared up with finishing the warm up and then started to settle down to around 1000. It turns out the idle is supposed to be set high to help break in the motor, also the motor at this point has a kinda floating compression, that is that it changes with every hour the car runs or every mile the car drives.

So I'm no longer concerned with my idle, It runs great, sounds good, doesn't bounce around or anything.

The smoke hasn't been since that one time and again that could very well just be the motor breaking in, I guess it's common for there to be some assembly lube left over which gets burnt off and what not. The engine is sorting itself out and it seems to be running the best it has. i wa stold that the engine will start to run smooth and have a steadier idle as it breaks in.

The lack of power I think might be the old BOV which defifnitly needs to be replaced( my new Blitz SS is on it's way from Tokyo).

All in all I'm not nearly as worried as I was, i think I'm just overly concerned as it is a new motor and I don't want anything to happen to it.

Take care. Now I'm looking into my rear diff squealing and my stiff ass stearing.
