Of those three vehicles, only one had been equipped with a NorthStar engine: The Oldsmobile Aurora. If a car is made longer by a longer wheelbase dimension, its proportional width results in more cabin space - another hallmark of a luxury car and there are many more hallmarks that no longer exist. Rear wheel drive applications have the starter mounted on the right side of the block when viewed from the flywheel and on the opposite side of the block than front wheel drive. Finally, the intake manifold is Nylon 66 thermoplastic, which its engineers explain that this helps cool intake air by conducting less heat from the engine. Early Northstar required premium grade gasoline to run safely. One of the hallmarks of a luxury car was its smooth ride. For the Buick V6 231 3.

My local mechanic was kidding me about it when I took it in for an oil change, telling me that the intake has to be removed on these engines to just replace the starter! It is a derivative of Buick's 215 cu in 3. In addition to the aforementioned problems, Northstars of all years have a nasty habit of blowing head gaskets. The Lucerne with the Northstar is a great car, albeit some mechanical problems have occured in owners' vehicles. In fact, I still have that car! It's even more economical in city driving than the Lucerne.

The relatively small offset did not require flying arms to be incorporated, however a 3 mm 0.

The Northstar V8 has been around since the Lucerne's introduction in the fall of 2005. It has to be something related to the failure and repairs made.

My first car at age 16 was a Buick, so you aren't alone! The cam covers are magnesium for light weight and sound damping. A typical oil change used 7.

But, when I think Buick, I think V8 power and luxury, with class and style, all in one package. And we also think you arrived here were looking for these details, are not You? Although the actual bore spacing between cylinders on the same bank remained unchanged at 4. The easiest way to spot the difference between the Gen2 and Gen3 is the smaller pulley and the ribs on the side of the Gen2 extend all the way down the sides, while the Gen3 ribs stay on only the top, they perform sightly differently and interchanging one without tuning may result in strange behavior of the engine. As far as performance with the engine I will point out that 0-30 is geared quite high and acceleration does suffer. The cost of building this engine was high, and it was not used in many vehicles.

The Northstar was on the list for 1995, 1996, and 1997. The compression ratio for the L37 is 10. Intake ports are mildy improved, 1. Far and away, most of the Northstar's issues have to do with oiling. The cleaner and dissolved crud is then vacuumed out of the cylinders through the spark plug holes, followed by an oil change. Please leave a feedback for us, we hope we are able to provide much more helpful information for future content. I have had this car for 5 months, upgraded from a 03 Rendezvous so I can't speak much to reliability.

Since the cylinders center-lines were no longer centralized over the crank pin bearing journals, the connecting rods were re-designed with the big-ends offset from the piston pin ends by 1. Up until 1999, the maximum oil change interval under ideal conditions was 7,500 miles. The crank pins associated with the opposing cylinders were offset from each other by 30°. I am satisfied with how the NorthStar engine performs, I think the problem is in the transmission, and I wish there were some performance upgrades for this engine. Btw, a Northstar V8 can easily out run a Civic 4 cylinder. The bore was enlarged to 3.
