Ian123 all of my trucks with powerstrokes were broke in pulling heavy loads. When i buy one i hook it up to my gooseneck and dont unhook it for two weeks. All of my trucks never give me any mechanical problems with turbos or injectors or any part that is not a common problem. My 97 psd was still running strong with 300000 miles when it was wrecked. My 99 psd is still running strong with 275000. My 06 psd has 145000 miles and it too is running strong. None of these trucks have been to the ford place except when they were new. I beat the hell out of them and they just treat me better. The one truck i have that i am expecting to give me problems is the 09 duramax i bought. I will never buy another one again. It will be traded for 2011 powerstroke next year. Gm quality has really gone down hill. To me it is like driving a dodge. Everything just seems cheap on it in the cab plus the under carriage is no way built like the ford. I can see why so many people have problems with the frames on these trucks.

 

i own a 6.0 myself and it's been a great truck. i see a lot of young hotbloods talking about rolling coal into the car next to them, i'm afraid thats going to backfire on us someday.so be careful of them tree huggers.they do have pull in washington

 

The 6.0 got a bad rep because number 1 international was rushed into production. 2 your white collar workers started driving them to and from work 5 miles not letting the truck function properly. 3 people started tuning them outside the engines capabilty. 4 the diesel techs were unfamilar with the new emissions equipment that there was alot of miss diag. I will bet for every 1 bad engine you can find 10 good ones

 

Some of that is true. But the one I bought, the prior owner put 93k on it in almost exactly 3 years and it still had an egr/ oil cooler issue. Was fixed under warranty, but Chevy's with roughly same system don't have that problem.

Though if you read this site, you get the feeling that 90% of all 6.0s have ongoing issues.

 

Majority of the ones with problems are running tuners. Horsepower on a diesel engine should be 60% of the torque. Torque is what does your pulling not horsepower. You can have 1000 horsepower but if you only have 1 ft lb of torque you will not go anywhere far. Thats like straight piping a diesel raises horsepower but drops torque. Look at all the heavy hauling semis. They dont run straight pipes like the smaller haulers. Now that being said i still like the sound of a straight pipe. Nothing sounds better that a truck loping with a straight pipe.

 

I think that time has already come. It's so obvious, my 9-year old son can see it, yet the locals around here cannot. Just the other day my son and I were at a stoplight and three cars up was some jack-hole with a modded Dodge diesel. When the light turned green he hammered it, turning the whole stoplight black for 100yds back, I could hear that rattling thing over my stereo, which wasn't exactly at a whisper. My son asked me what was wrong with his truck and I told him the biggest problem was in the driver's seat and that guy would be the first to wonder why he gets a ticket and the first to whine about tightening diesel laws, as would some guys here...

 

California is already setting up smog stations for diesels. There is talk about a program to turn in "smoking" diesels. That is one of the many reasons I am leaving this "fine" state.LOL

I am not in agreement with smoking out an intersection, but not a fan of being "TOLD" on either.LOL


I am FORD through and through. I would stay away from the 6.0 and early V-10 for sure. I don't need anymore problems than I already have.LOL JMHO!

 

I see nothing wrong with a puff before the turbo spools, fogging the road is different.

What is wrong with the early( 97-99) V10?

The only thing I don't like about Mine is the non PI heads.

 

Bill, aren't those the ones that spit plugs?

What are PI heads?

 

Mine has never spit a plug, I have never seen one that did.

Performance improved heads, ford started using them on the V10 in 2000.

The 97 to 99 V10 had 265-275 HP, the PI heads give them 305-310. Ford went to 3V heads with 362HP on the pick ups in 05, but the Excursion and E series vans never got them and kept the PI 2V heads.

 

Were the combustion chambers smaller or are the valves larger on the PI heads? What makes them a performance improved head?

 

Once again, we are in agreement. I love this state, but hate this state's politics and regulations. I've been on the prowl for machinist jobs on the Oregon coast, but thus far have come up empty. If money were no object, there would be nothing but a vapor trail left where my family and I high-tailed it north.
As far as the regs concerning (pretty much anything), I've been around long enough to know that quite often it's abuse that brings on the posse of lawmakers. I remember when I bought my first sportbike back in '86. There were very few in my area and we kinda snuck in under the radar. Never got nabbed or harrassed by the law, despite clandestine triple digit speed runs and late-night street racing in deserted areas. Stupid, yes, but I was very young at the time and made very sure I was never seen by John Q. Public. Then came the wave of popularity and all that comes with it, loud pipes, wheelies in town, riding fast in town, cutting off cars, passing on blind turns. Next thing you know, my favorite road was also favored by the law. Just riding a sportbike was cause for alarm by the CHP, and lots of guys were getting tickets for a myriad of minor violations designed to calm the public. I quit riding with freinds and eventually sold the bike. Same with dirt bikes, hot rods, ATV's or skateboards, it's all good as long as everyone behaves. But people don't behave for long and the next thing you know the "hey check this out!" mentality surfaces, and it's all huge, loud pipes followed by PO'ed citizens. Followed by overzealous lawmakers. Make noise. Get noticed. Get outlawed. Or enjoy your present rights and do all you can to preserve them by acting considerately of others. Stealth wins wars.

 

X2. Great post Sand_man!

Tried to rep ya, but gotta spread it around.

 

Like Chrismas presents, it's the thought that counts! Anyway, speaking of goofy California regs, do you know that there's a movement to outlaw woodburning stoves? I kid you not, the communists..err..environmentalists are requiring catalytic converters on wood stoves, and in some California cities, they are illegal altogether. Is there anything more primal than man being warmed by burning wood? It started in cro-magnon times, and now is being blamed for the destruction of civilization! Know where 99.9% of all insane California laws come from? The SF Bay area. This is the same city where for shockingly little money, you can see any perversion you like and get a beer to go with it. Wanna marry another man? No problem. Wanna parade in the streets in support of your drug of choice? Okie-dokie. Wanna see a live sex act that would make most people sick? Right this way. But hey, if your gonna cut down innocent trees and use their carcass to warm your home, you're in the wrong town! I truly hate this state's politicians. Sorry for the long OT rant, but it's been raining and I'm suffering from cabin fever...

 

The exhaust valve is slightly larger,the combustion chamber different, and the intake port is a different shape (pistons dish cc's changed to keep compression equivalent). The camshafts have more lift (.466 in/ex on the NPI, and .510 in/.530 ex on the PI), along with a slightly different intake manifold. The gains are really only from the intake manifold, camshafts and the tuning. The cylinder heads themselves do literally nothing for power gains-the PI and NPI both flow almost identical amounts of air on the flowbench,and the NPI actually has a better intake port.
