6.4L Power Stroke Engine and DrivetrainDiscussion of the 6.4L Power Stroke diesel engine and drivetrain in the 2008 Super-Duty trucks. No gas engine discussion allowed except on transmissions and drivetrain that pertain to all models. Please confine discussion of topics in this forum to those items that are specific to the 6.4L Power Stroke engine.
just booked 6.4 lt dit in my shop to do headgaskets ,,goin to do it next week,,done hundreds of 6.0lt's.......only done one 6.4 before ......anny upgrades available other than head studs to stop further head problems as head design same as 6.0 .. ??
does the cab have to be removed? and if so what about just to put studs in the head and not remove it?
yes cab off to do gaskets,,,,made to remove cab as bolts up from botom,also i am doing studs and new gaskets as block surfacs are same as 6.0 and rust badly.........anyone know if any aftermarket head gaskets with a built in fire ring as stock does not have one ,,,they are almost identical as the 6.0 gaskets............have cab off of 2004 6.0 and compared gaskets from 6.4 kit and vertualy same.....hope this is not the start to a nother 6.0 fiasco!
possible to do head studs only but IMPOSSIBLE to do head gaskets without removing cab on 6.4,just finished ones on this one,way more labour than 6.0,way more money and time and parts as all high pressure lines and egr bolts and gaskets must be replaced,special torque sequences also on all egr coolers,brackets,pipes and band clamps,i useta ***** about the 6.0 head gaskets but these ones are out of this world.......first 2 cab bolt blind nuts broke and had to be welded ,what a start......hope this is the only one i have to do and all the rest hold together!!!!!!!!!!!!!!!!!p/s early build date job 1 trucks have 6.0 gaskets and not updated ones....enjoy
these head gaskets failed from his chip,he has a das dacq programer(think thats how to spell it)can get up to 350hp tunes,he told me he had it over 1600 deg exhaust temp once,#5 cyl had clean star patern on piston and blue upper cyl.no damage luckaly as these motors have a tendancy of melitng pistons from inj. probs.head was warped .07 had to be machined......i dont think head bolts are the prob as i had to use a 4 ft snipe on my snapon braker bar to loosen them,,impact would not even budg them......also some posibilities is the heads had tiger stripe machinin groves on them ,same problem that plagued 6.0,mls gaskets wont seal unless it has a extra smoth surfaces.......p/s this truck only has 55,000 km on it and ford flaged it as having power chip ,so no warrenty any more....i installed elite studs....new ford gaskets are coper in color,black sealer in between mls layers and 3 thin layers and one thick layer,different from 6.0 multi thin layers,they look like a better gasket but we all well know looks don't mean much

Well I am running a banks 6-gun on mine, but a low setting, maybe 50 hp and the thing about the banks is it maintains the factory safe limits. What do you think?

i think you should be fine,i dont know much about the banks chip but i would strongly suggest a pyrometer and run no more than 1400deg at manifold,this guys chip was on 210hp seting and has dpf deleted,i would be more worried about an injector failure as dealers have deen replacing engines for melted pistons from inj.failures

98% of the melted pistons are caused by over full crankcases. At a certain point oil gets sucked into the fresh air inlet tube via the crankcase breather tube, fills up the charge air cooler with oil/fuel, and will work it's way into the intake manifold. Usually takes out the left bank, cylinders 2 and 8 first. It's usually caused by an external fuel leak at the injector fittings or the high pressure fuel pump itself. I've had others where it's just a total lack of maintance and the truck runs 16 hours a day (1 hour equals 25 hours). The truck would have 12,000 miles on it but 880 hours, so thats 22,000 miles without an oil change. The crankcase would get overfull for the excessive idling and have the same effect.

Elite has a fire ring set available for the 6.4L I believe the adding of an upgraded intercooler and maybe a snow meth/inj system as well, would deffinetely help lower those EGT's, maybe an EGR delete from elite as well but seems to risky to have to weld on such a new vehicle.
we should not forget the fire from exhaust when job 1 trucks had bad inj. causein dpf fires,that was not caused by fuel in oil......good to see ford folowing on duramax footsteps

Wow thats reallly f***ing disappointing! I'd heard that people with failed gaskets noticed a difference when they went to put the new ones in... but had no clue that some of us got the old 6.0 gasket.
I'm surprised so much of an issue from running the 210. There are 3 levels above that with MUCH more power. It's funny... most guys have no problems on those levels, but I'm starting to suspect that the reason why some people can run the high levels and beat on them all day, while others run medium-high tunes and blow gaskets... just may be the gasket difference.
There was a thread on another forum where a guy started to notice a trend w/ the build dates and head gasket failures. Guess this explains it.
