Hi there,

First, I actaully just got the car yesterday. This is what I have receipts for:

The engine came from Malloy Hyundai-Mazda-Kia located in Woodbridge, Virginia in October It's part # F008-99-008R-48 REMAN, ENG. The engine was installed by John's Automotive in Aberdeen, Maryland on 11/6/04.

Yes, there is a 1 year or 10,000 mi warranty on the engine. That is in effect until next October I'm guessing.

Second, I really don't think that the apex seals are blown. Not only because this motor is fresh but because the car runs good, it doesn't idle way erratic or stall, it starts and runs, just idles higher than I think it should. I think she should be down around 750-800 rpm but she idles at around 1250. The motor doesn't exhibit the death shake, it actually revs very smooth and has excellant power and pick up until you give it alot of throttle.

The main problems are that the car idles high, it emits a lite white smoke from the tail pipes and loses power when you gun the motor during accelleration. I'm thinking either an EGI issue such as pressure sensor or leaky intake line or possibly a bad collant seal in the turbo.

I didn't persoanlly check the level of gear oil, I will do that though. I'm thinking the best thing to do would be maybe rebuild it again. I am not aware of exactly what was done to it during the last rebuild. I was told that it had the "pinion gears" replaced. How hard is is to rebuild a rear? I got the service manual so I think I'm gonna be doing some reading.

Please let me know what you guys are thinking. Anyone ever had similar problems with idle, smoking and loss of power during hard accelleartion??
