Note that the BMW M3 has a V8. Roger Smith is long gone so you can forget airy thought at the top leading to things like the 368 cid V8-6-4 or a 4.1 liter engine in a 5,000 pound car. I agree that Northstar has another generation in it to cover where the High Value V8 would have taken over. Some of the thinking that I was seeing in the High Value V8 was modular thinking, like the Ford Modular V6-V8 family where the same factory builds engines...

QUOTE (Jan Olsson @ Nov 7 2009, 03:46 PM) Many testers feel that the Cadillac V6 isn't as smooth as the competitors V6 engines, then they test the Northstar engine (IMG: style_emoticons/default/tongue.gif ) Personally I feel that a 90° V8 that can be fully counter balanced with respect to the 1:st AND 2:nd order of vibrations always will be superior to a V6 who in many cases need to be counter-balanced for a smooth run....

How about the standard tip: checking for codes? Sure, it is possible to get better gas mileage if you skip emission control systems (like the cat), but then you also have to program the PCM accordingly. Unless you have reprogrammed the PCM (few people would pull that off, I think), it is still programmed for having a cat, which means that it will try to maintain the stoichiometric ratio of gas to air (meaning that there is just the right...

yesterday on the highway it went up and down. for awhile it was at 10.8 and did not waver. oh oh, i thought. that can't be good. than it went up to 13.5 and we know how much of a pain it is to remove. seems to me the a/c compressor is in the way if you take it out thru the wheelwell. i had the a/c compressor off this summer. not real hard. i think if you take out the cooling fans, it can be reached if you reach down far enough.

QUOTE (Julio @ Nov 7 2009, 12:43 PM) still looking for a fix on this, getting brake light on traction control lamp on and abs light on also message service stability control sys. All data has little to offer in isolation though it says all these codes are controlled by the ebcm, I have good grounds pins f & g on the EBCM connector. Would the Steering position sensor cause the brake, abs and traction control lights to...

And also take a peek on Amazon.com for the parts... I've been finding LOTS of parts that are being sold from closed/liquidated dealers at total give-away prices (even cheaper than RockAuto, who I love!) Just type the part number right into Amazon... it's sort of surprising what you'll find!

QUOTE (growe3 @ Nov 7 2009, 11:28 AM) Assuming the temperature gauge to be correct (the temps are well within normal) , the water pump belt may be slipping slightly. As the engine speeds up from the lower gear ratio, it will move a little more coolant through the system. 1. Check your water pump belt for wear, and cracking. It should be flexible, and without cracks on the inside of the belt. A hard belt will tend to slip, a...

Another reason to prefer a V8 (or more) in a luxury car is the smoothness, both a lack of vibration and a soften the pulses of the exhaust noise. Back in the days of the V16, lots of makes had a V12, because they were easier to balance. Everything is built to a price and purpose, and the Northstar had many objectives when it debuted, and the primary one was to steal Lexus' thunder. The LS400 debuted in 1990 with a 250hp 4.0l DOHC V8 when...

there are lots of things you can do. you make sure the oxygen sensors, engine emissions system, and evaporative emissions control systems are in good shape and well conditioned. always plan your trip and lighten your load.
