I think your biggest thing should be looking into new tires, 79k is pretty high mileage for a set.
 
Other than that, my 2002 just hit 109k. Never had belts changed, after I asked the mechanic to look at them, he said not to bother, all the other stuff you mentioned i did for the first time at 100k, except for air filter.
 
been such a low maintanence vehicle.
 
the only issues were redoing the brakes around 70k, got screwed by midas on that.
had two rear shocks replaced at 100k for cheap.
 
of course my fan clutch is LOUD, but the mechanic said it would prob cost $400-$500 and even then he couldn't guarantee the new one wouldn't do teh same thing.

Is there a specific range of RPM's that it continually knocks at? Try reving the engine in park and seeing where on the tach the knock occurs. Also, once it occurs, listen to see if it's get worse briefly after you let off on the accelerator.

It starts at around 1500 to 2000 rpm's and knocks continually. Yes it does get worse briefly when I let off the accelerator...thanks for the quick response.

It could be a loose rod bearing. The classic way to check for loose bearings is to remove the plug wires, one at a time, and rev the engine through the rpm's where the knocking occurs. When the cylinder with the loose bearing is dead, i.e. the plug is disconnected, the knocking will go away or be greatly diminished.
Before you do that though, is the knock a loud metal to metal sound, or is it more like a click? And is it worse when the engine is cold or when it's warmed up?

it sounds like metal to metal to me not a click more of a "klunk" sounds the same cold or warmed up....I was reving it earlier to let someone else hear the klunk and the check engine light came on as well...very frustrating!!!

GM V8 Engine Oil Problem by drewmich
Aug 08, 2009 (11:20 am)

My wife and I both have Buick Rainer -V8s - 2006 & 2007.
 
My wife's 2006 which has 50K mikes on it - is burning way too much oil - about a quart every 1500 miles. There are no leaks or drips on our garage floor and I don't see any blue smoke coming from the exhaust. We regularly get the oil changed every 6,000 miles
 
My 2007 Rainer (35,000 miles) - uses a bit less - a quart every 2000 miles.
 
Is there a known problem with these V8 GM engines used in the Rainers? Any possible warranty claims?
 
What solutions do any of you techs have to stop the oil usage?
