    Anyone have experience with theses engines? Once you replace the head gasket and head bolts how well does this engine run and is it reliable after these fixes? Also i have the egr eliminator ...Thanks for any tips

    I have an 06 6.0. I love my truck. New headgaskets egr delete and arp headstuds have been put in and it is a great running truck. Not the most fuel efficient but ive been able to squeeze out a few more mpg's with some tuning and other aftermarket items. They can be reliable and then some are not soo reliable. Really depends on maintenance and driving style/ conditions. Some have had really bad experiences with them and others have had decent luck.

    I have arp headstuds, the egr delete, also custom tuned with an sct by innovative diesel and other stuff. Its my second 6.0 (first one was totaled) both had similar modifications. The first one was bought new and had 125k when it was wrecked. The current one I bought used with 108k on it and now has 151k. Both trucks ran/run VERY strong, towed daily and occasionally were taken to the race track. I drive my trucks very hard. No transmission problems either, the custom tunes take care of the transmission programming too.

    I love the 6.0 engine and I'd buy another one even if it had over 100k again.

    Ok. I just bought an 03 6.0 last night with 109,00 miles on it for 8,000 bucks. I drove it home which was about 150 miles away i park it in my driveway, and i smell antifreeze, the reservoir builds a ton of pressure which then cause the puking and spitting of the antifreeze. i did my research very notable on these trucks. I talked to the guy i bought it from, as he is a diesel mechanic and claimed that he didn't think it was a bad gasket, so long story short, is bad gasket/ and studs and i got an estimate of $2500 range, the guy is gonna send me a check for a grand which leaves me with a rough bill of $9500 total invested. Lesson learned: Do my ******* homework before any big purchase.

    So my question is just fix the gasket and stud and the egr delete ( which my truck already has on it) and i should be back in the rodeo with it? This is my first diesel and i don't know crap about them, but i will start learning now.. Thanks guys..

    Typically the earlier years of the Powerstroke 6.0 were more problematic than the later years.

    One of the ambulances that I worked on during the summer is an '06 with the 6.0 Powerstroke in it. The engine (and I think transmission) was just replaced in the spring or early summer. It had around 200k on it when everything was replaced. I know its had its fair share of problems too in the past. But it is driven HARD, more so than any other truck I know of. Hard acceleration, hard braking, high speeds and the occasional curb hopping...not exactly "babied".

    The price you paid sounds like a good price. Even with a total investment of $10k into the truck and repairs it won't be a bad deal.

    As i said in your earlier post!!! That has been a problem but yes gaskets, arp studs! No substitute for arp's! An egr delete which you say it has and also drop 150 roughly on a coolant filter from somewhere like diesel site or sinister diesel etc... With these out of the way you should be well on your way to a good truck to last you a good while. I would also look into a mild tune for mpg purposes as these motors arent the best in that regard. 10k is not a bad investment for that truck with problem areas out of the way!!

    That also says alot for the guy you bought it from going to send you a grand to help fix the problem. Most wouldnt do that and you should be thankful you got it from a good seller!

    I have an 05 and 06 with the 6.0. The 05 which I bought used with 28K on it, unloaded on me at 90K miles and needed egr cooler, egr valve and FICM. It was 3 months out of warranty on time, but they covered all but $1000.00 on the repair. It now has 105K miles and runs great. The 06 I bought with 40K on it and now has about 66K and has run perfect so far. Both tow everyday and do a great job. I like the power compared to the 7.3 I have. I get about 14mpg with them towing, 16 without trailer. The 7.3 is a little better on mpg's.
    I have thought about the egr delete kits but haven't acted on it yet.

    I also have a one ton stakebody with the 6.4. It only has 20K miles, no problems yet except it sucks on mpg's with 10.5 average.

    From all the bad experiences my close friends have had with the 6.0 and all the bad things I've heard about the 6.4 even from dealers and sales guys I'll be sticking with a 7.3 until used 6.7s are at a reasonable price.

    Friend of mine I've known for many years told me the only way he'll buy another 6.0 is if some one gives it to him.
    Then hes gonna get rid of it while it still runs.
    Hes got two and hates them. Very unreliable engines for him.

    I'm with you;

    got a F350 7.3 harvester with 287,000 and still running like a beast.

    Also a D3500 5.9 Cummings with 198,000 also running like a beast.

    Probably keepers till 1,000,000 or until the body rusts out which ever comes first.

    If I have to replace any of the trucks, I'd look at the Dodge with a 6.7 in line 6 Cummings. The F 6.7 v8's are having some minor problems still, like the block splitting after a couple of thousand miles. That's what happens when you reverse engineer a gasoline engine; GM did the same thing in the late 70's early 80's on their passenger vehicles, they sucked then too.
