I kept losing water, no leaks, started to un screw the cap on the coolant thingy to release pressure and it shot off and across the yard. I think the head gaskets are gone. Didn't know it was as easy to do in a 7.3 but figures if it can be broke, I can brake it. I took the thermostat out and its not broke, it moves freely.

Anyone know of a way I can check to be 100% sure its head gaskets? should I replace head studs too while its apart or is that not needed on 7.3?

2003 7.3 What do you guys think?

 

are you sure its head gaskets and not injector orings?? any oil in the coolent thingy lol..or water in the oil?? how does she run?? not sure if studs is going to help you much with the rods you got..but it wouldnt hurt....

 

Subscribing to hear the answer.

 

uhh. no im not sure it is a head gasket...runs good. Havent noticed a severe loss in power if any. no oil in coolant..not sure about coolant in oil....

 

Could be an injector cup, or head gasket. Seems like you'd see some seepage around the heads if it was a head gasket.

 

good lookin truck nevertheless

 

What mods do you have? Are you making alot of power? I cant recall the last time i heard of a 7.3lifting heads - but i do hear about bads injector cups/o rings all the time.

 

Stock injectors, no big mods other than a chip, he lives close. Im goin to take a look at it in a few days when i get a chance. I can't say for sure what it is without looking at it. Even then, i dont know if i could say for sure.

 

kris has said it. I hope we get the problem worked out. Ive been having a lot of troubles with it latley..thinking about a 6.0 or possibly even a new 6.4! but Im gonna miss it. I just wish I didn't have so many problems with it...and 140+ miles

 

Im not sure about others but problems with my truck seem to come in 3's or 4's. We run the crap out of my truck so i expect repairs but right now i just cant keep up. Its not the fuel but the expense of the parts everytime something goes bad. The though of selling it has come up more and more often - Switching to a Chevrolet Isuzu W series box van possibly. Larger payload in the truck, less towing. Parts are cheap as can be and repairs couldnt be any easier. Plus those 4 cylinder isuzus run forever.
