By the way, any engine is prone to leaks, so its unfair to single out the Northstar as a leaker. It is expensive...look what kinda cars it goes into...
yeah, really. The 3800 is prone to oil leaks too!... or has everyone forgotton about the leaking valve covers, etc.

I have a stupid question for you guys...

Is the water pump belt driven or timming chain driven?

I know on the older models tha PS pump and Water pump were driven on the passenger side of the engine.....

On another note, I didn't say all N* were bad... I have seen more than a few that had problems... And it would keep me from buying one...

I have seen a 3800C, 3800L, 3800K( 2 of these, Thrown rods on both ) all go to crapp before 200,000 miles...

Also I'm guessing that the 3.5 is going to be a 90* V6 as well as its designed comes from the 4.6...

No matter what we say the choice is his... If he wants a V8, thats ok... If he wants the V6 econmy, well thats ok too...

The only problems that you MIGHT have with a heavily used N* is the head gasket...On the newer ones, i would recomend in a new york minute.


Three great modern engines from GM
3800 V6
Ls1/Ls2/ Ls6/Ls7 Small-block V8

I say look into the SSEi'* also....because they're very reliable engine....Previous owner treated my SSEi like **** when he had it, wrong octane, barely changed the oil, blew the trans.....Well I'm at 206K miles and still running great....Kinda a goofy idle.....but all things considered by the club members that have seen it....She'* a pretty mean machine.

I have owned a 3.8... a SSEI 3.8... and a GXP. The standard 3.8 was by far the best one I had. It is still in use by the lady I sold it to. The SSEI was bought used and I think it may have been a repo as it turned out to be a POS. The GXP is being bought back by GM. You can read about it in another thread I started on it. As far as the oil leaks in the NStar, the mechanic I deal with told me the earlier versions had a sealing problem that was fixed by changing sealers. There are many people that are happy with all versions of these cars and it seems to me that it all comes down to how much luck you have the day you pick it out. Then again that could be said for any line out there. Good luck to you.

my 97 aurora just hit 100,000 and leaks a little oil from the rear crank seal, but only about a half quart per 3000 miles, all my leaking is coming from the radiator... and spewing dexcool evertywhere and making a mess... that reminds me... i should fix that some day....

my 2000 bonnie has 88,000 and runs like a top, and doesnt leak a drop of anything
