N62 Engine....

[Wolfsbain]

Gents,

I just purchased a 2005 X5 4.4 since my 2003 X5 3.0 was written off as a loss after a collision. The lot dealer said that the head gaskets were changed and that was the only real problem with it. But, at start up, it makes a squealing noise for a minute before it stops and runs normal. As it's doing this, the engine sounds like it wants to stall like it's not breathing, then all of a sudden, it's like it catches it's breath and runs normal. Any clues?

Also, I have the Bently Repair manual for the E53, and I loved it when I had the 6 cylinder 3.0i. But I see it hardly references the 4.4i N62 Engine. I'm not happy about that. That book was my bible! But, I've been reading about the "improved" N62 engine from the M62 and all I read is some bad stuff. Now I'm seriously considering trying to trade with someone for a 3.0i. Does anyone have an N62 Engine that can tell me a little about it?

Thanks!
