puke on 275?

[Brayden_ryder]

okay so today i was getting all excited on ordering my spartan and running that 275! This was until i stumbled upon a thread on powerstroke nation, on people running the 275 and 310 who are puking coolant and blowing heads. now i was not familiar with this and i thought myself as pretty knowlegable towards tuning and 6.4's. i have a job 3 and if i am correct they have slightly different head bolts than the earlier ones. now i have extended warranty so i dont want to be doing any major noticeable mods ie. egr delete, bov, etc etc.

i would like to be reliable and i thought the 275 was completly fine in this category.....am i wrong?

I think it could have something to do with the colder weather aswell. I would also like to know what the diff is in head bolts from job 1 to job 3

It has to have something to do with the cold weather.....I've been reading on this forum since april and it's funny that the puking issue is just taking off the last month or so.

mine started puking in cold weather, a year ago christmas, this year christmas it got new headgaskets studs one head horizontal egr cooler, updated coolant hose and 4th radiator under warranty....

i run the 275 on 2 08 f-250s and the 310 on 1 08 f-250. i have never run anything else since new. i drive them normal in freezing cold temps and have never had one puke. get the spartan, drive it normal with a blast on occasion, and enjoy your truck.

I just had the head gaskets done on mine, they blew running the 275, I think it has a lot to do with high drive pressure more than cold weather from what ive read

[Brayden_ryder]

so i know its the high drive pressures that causes it, so any temp below freezing do not run the 275?
i really do not want to have reliabiltiy issues with my truck but will running the 275 just make things worse?

[Matt P]

I wouldnt run it on long trips on the highway, Id probably run a lower tune in the winter as well

[Brayden_ryder]

so daily driving around 60/40 city hwy driving would be fine?
i know you were the one on powerstrokenation who had the problems with your truck even though you babied it. Is yours a job 1?

[Matt P]

yeah mine is a Job 1. I was easy on it but I did about 4k miles of highway driving on the 275 before the gaskets blew, the month before it and I think that had something to do with it with the drive pressures during that
