    how to rebuild a 2002 7.3

    hell no i wouldnt have them do it anyother way. they measured it to see what the smallest oversize bore will be. then i ordered .030 over pistons and they miked the new pistons and bored it out according to the measurments of the new pistons. wouldnt have it done any other way.

    how to do ebpv gutting and aih deletein

    this is what i was refering to as far as the pedestal modification to me the way it is explaining it if you remove the piston it would starve the turbo baring for oil? mabey im just not reading it right..... If you simply plug the hole and leave the sensor plugged in, you may cause yourself...

    results of my compression test readings, please interpet

    opened it up there is one cylinder that has been gouged by a broke piston ring. It wore a nasty groove in the cylinder wall, hopefully it can be machined out with less than .030 over other wise i might be lookin for a short block. the rest of the bores were ok other than some slight ware i...

    rebuild dont know of any mods to do, i think the bottom end of the engine should be plent stout enough in stock form for what i am gonna do with it. I would like to gut the ebpv whle the turbo is off and take that air intake heater off, but other than that it will be done stock i think.

    no just stock injectors, they are brandnew ones thoug i just replaced them about 4 or 500 miles ago. I borrowed a freinds gauge that goes up to a thousand psi, stil the same readings on the lower compression cylinders and the ones that i was guessing 300 are realy anywhere from 275 to 350psi...

    Cold start

    low compression according to the ford tech he said after you have exausted all the possible causes to check the compression, a deisel fires off of compression so if the rings are worn out then it wont have enough compression to fire it off. have ford check that and see, the rings shrink when...

    how to rebuild a 2002 7.3

    what would you guys say to this i warmed the truck up and then got the tempeture gun out and read each individual tempature at the exaust port. two of the temps where a lot lower than the others so that leads me to beleive those 2 cyclinders are not fireing, any ideas what could be cousing this?

    how to rebuild a 2002 7.3

    ? when i put in the new injectors i did replace the glow plugs also but i did not replace the UVC harness or the valve cover gasket. The only thing i can think of is that the wireing harness that plugs into the valve gover gasket on the outside of the valvecover is majorly dry rotted and i can...

    how to rebuild a 2002 7.3

    yeah i havent had the truck long only about the last 1000 miles. The reason i thought it might be compression related is because the truck is very hard to start when its below 60 degrees outside but this could be a lot of things, i checked the glow plug system and everything is fine there, i...

    how to rebuild a 2002 7.3

    not that i can tell, i changed the oil in it 400 miles ago and the oil level is still the same from what i can tell. but 400 miles might not be enough to tell yet. the blow by out of the oil fill tube is not that bad i dont think, when it is idleing i can put the cap ontop of the oil fill tube...
