Upgraded to a 04 4.4i - question!
 

I had a 2002 3.0i before and decided to move up to a 4.4i. I pretty much know all about what I should expect with the 3.0 (M54) in terms of repair/maintenance.

Can those with experience with the 04 4.4i (N62), give some advice on what I should look to take care of now before it goes? WP/pully/CCV etc..etc.
It has 115K miles on it?

Thanks

Valve cover gaskets, CCV (its really easy), Probably waterpump, My alternator also had to be replaced. Oil leaks..

The N62 engine is notorious for the weep hole coolant leak. If it hasnt happened, then it will very soon.

Do a search and have at least $1500 ready for the repair.

Ive never heard of that.. I never had one come into the shop either

Its very common on the 7 series. There is plenty of reports of it happening on the 5 and 6 aswell.

My 04 N62 X5 is currently in the shop getting the repair done and the mechanic told me hes had two 7's in the last month with the same issue.

Do a quick google search, its pretty worrying.

Timing chain guide rail.
Preventative maintenance is pretty much the same on both model.

Thanks for the reply guys. I had the dealer do some work before I bought it. Boots, some leaks, trany sleeve leak. It has a strange vibration when standing still in drive but fine when driving no wheel shake. Someone told me it could be the motor monts - they have seen this before with my model. Will have to look into that and take care of the WP/belts/CCV when this weather in GA realize that it should be spring.

I could be wrong, but I think the timing chain guide rail issue is more prone with the M62TU V8s (2000-03) moreso than the N62 (2004-06)...I'll let the professional wrenches chime in about this. :)

The N62 suffers more with the violent shaking upon cold start-up from the valvetronic intermediate levers vs the timing chain guides on the M62TU.

LOL...not sure I should be worried or happy after reading that attachment...

Thanks Qsilver7 for the correction.
