I bought a new cap I'll definitely be trying this with my old cap thanks for the idea

 

Since all this has started with changing thermostat I bought a oem motorcraft one gonna install it and try it today hopefully it makes a difference but we will see thanks for ur guys help if u got any other suggestions let me know thanks for the help

 

Well it's definitely a blown headgasket or cracked head or block or something along those line I completely drained radiator and left upper hose lose installed motorcraft thermostat and started filling it with coolant when it started coming out top of radiator I reconnected top hose finished topping off coolant and started truck drove it for a bit all was well had head again no leaks then parked truck and let idle for while sitting in truck next thing I know I lose heat and temp guage still shows cool get out no leaking water pop hood and the degas bottle is completely full to top so I start loosening cap while truck is running start spewing antifreeze lots of bubbles but it's only luke warm in definitely sure I'm getting compression into water jacket well guess it's time to put my spare motor in thank you guys for all your guys help

 

Can you do a compression test? Then a leak down test at TDC?

If you pass the first the second may tell you if it is heads or cylinder walls.

 

Well for time sake and kickness my brothers gonna let me use his engine for his single cab obs in mine just gotta put my injectors and turbo on it and put it in it's completely re sealed and ready to go also gonna put my brand new valve cover harness on it and install it and after he gets enough money saved we will reseal my spare motor and put it in his truck he's put that truck on the back burner since he bought his 99 crew cab 7.3 but should hopefully get it in this weekend if all goes well here's a few pics of it

 

Well here's how far I've gotten so far

 

Good progress, wish I can start on my POS lol...

 

Well got the motor and tranny out here's some pics gotta pull my new turbo and injectors and put them in other motor and I'll be good to go

 

Well here's motor with new clutch on it ready to go onjust gotta get my injectors in and turbo on it should be ready to put in tomorrow if all goes well can't wait to have my truck back also gonna throw some new headlights in to excited to have it back

 

Also going to 175 cc injectors to while it's down and getting a manual chip and computer no more lopping on start up

 

Well got quick question should I run headstuds with 175s and the turbo I have I'm also installing a 6.0 intercooler while truck is down

 

Because I honestly am tapped out now so headstuds will half to wait but wondering what u guys would suggest

 

Something crazy is that in the room the last picture was taken in there is 6 7.3s in and outside there is another 4

 

The turbo PSI is what determines if you will need head studs, but not just studs you will also need stiffer valve springs and chromoly push rods or else you will get valve float and damage your valves.

 

At the time being I was just planning on running it detuned so I don't damage anything and soon as funds are available I plan on studing it and install valve springs and all the nessesary upgraded I already have guages exhaust and efuel and turbo just wanting to make sure I'm not gonna turn around and blow my new motor up with these
