think the headgaskets are gone agian.

i fire the truck up and after about 20 seconds if it running i have about 10psi of pressure in the rad bottle, i was goin up a hill the other night and i could smell coolant, i pulled over and seen alittle bit on the bottle, i was alittle bit pissed off about it cuz i kinda new it was probley headgaskets so i ran it alittle hard on the way home, fired it up the next morning and it basicly pukes sittin there idiling. did the headgaskets about 10000k ago, has studs egr delete new oil cooler ect...... i did use those black onyx gaskets then after i herd people have been having problems with them. just want some reashurance that its probley the head gaskets.

Sounds like it to me, especially if the egr has been deleted and I doubt the oil cooler would plug that quickly. By the way when you did the head stud install, did you use ford gold coolant or something else and did you put a coolant filter on?

[whiteboy_77_77]

did not put a coolant filter on ,i used prestone diesel coolant, i think it was red. even if the cooler was pluged it wouldnt puke without the egr cooler would it??

[windrunner408]

No it wouldn't. It would only come from the cylinder pressure at this point since your egr cooler is gone.

i guess i know what im doin this weekend haha. thanks for the help man.

[windrunner408]

Well I'm truely sorry to hear that. I dont know if you did this or not when you did this last time but if not I would recommend not only using oem head gaskets this time, which I'm sure you will, but also replace/update the dummy plugs, stand pipes, and all of the injector orings and seals just to be safe with the HPO system.

When the studs were put in, did you have the heads sent out to a reputable machine shop to be checked for flatness, cracks, and pressure tested?

[jensenrcng]

i feel your pain whiteboy... im doing the same thing with my truck right now. black onyx gaskets and studs last time also...

[whiteboy_77_77]

just after i put them in i noticed alot of people sayin they went for a **** soon after they were put in haha, but ohh well **** happens. atleast i actually like working on these trucks and it isnt all to hard of a job just alittle time consuming. and yes i had the heads shiped out , pressure tested and alll that junk. they plained them .003 to get them true, I thought it was kinda wierd how quickly they went south. I drove from vancouver island to saskatchewan and back , like 7000kms total with out a problem put maybe 3000km around town here and coule barly smell it goin up a hill then was alittle hard on it for about an hour and now i cant keep water in it. and it will sit all pressered up all night and when i start it in the morning it flashes up , no misses no smoke no nuthing. just thought it it was coming out the bottle at an idle it would be just as easy goin back into the cylinder? i know they have 450psi+ of compression to aid with pushin gasses out of the gaskets.... but still sitting all night at about 12psi all night you would think a few drops would seap back in ??? am i wrong?
