4.6 or 5.4
I have a 2002 f150 supercrew with a 4.6 i posted some head problems that I was having it will no longer hold pressure in the radiator and I have to add water every day to go to work and come home...the truck still runs great I cant find a leak anywhere . I cant afford a rebuilt so I will most likely resort to getting one out of a wreaking yard but some people say get a 5.4 .what would I need to do or change if I did get a 5.4.Would it be worth it I really do like the 4.6 even thou I'm having the problems I'm having. Thank you I really do appreciate the help and advice

Your wild thinking may cost you a lot more money and hassle.
Find the coolant leak first.
If your losing it at that fast a rate it has to be seen at some point.
Pressurize the cooling system to find the leak.
The coolant just does not disappear into the air without a trace.
You have the hoses, the radiator, the heater and hoses, the line that runs through the block valley to the rear, and water pump shaft seal..
If you had a head gasket leak into a cylinder the motor would not run so well.
If it is going into the crank case you should see that evidence on the dip stick.
The radiator has rubber seals around the side tanks. They can be temperature sensitive and either seal with heat or open a leak with heat.
Look under the area for signs of a leak. Anti Freeze usually leaves a trail.
Shame to replace a motor for some lesser outside coolant leak.
Good luck.

Do an exhaust gas check in the coolant to tell this story.
If you smell antifreeze there is a leak to the outside world for some reason..
Is it the heater core?
It may leak when hot and seal when doing a cold engine test. Things expand when heated and contract when cooled. This happens every time you use the truck.
You have to keep chasing until you pin it down.
Good luck.
