It will pressurize the system if there is any bad parts hoses, radiator, water pump, intake,heater core, head gaskets
As it looses pressure you should see the coolant ( some times leaks are internal and you can see them but you will loose pressure )

I also bought one of the ebay snake cameras for 20 bucks I have used it to see head gasket leaking into the cylinders as well as bent valves just a thought

Its just a generic diagram showing the difference in head gasket leaks something I saw the other day doing some research granted ik that isn't the area its exactly gonna be at but it should help me in identifying. Oh and to Dave my oil I better drain her an save the oil cause it doesn't even have 10 miles on the oil

I had a head gasket go as in the diagram, 'compression leak to coolant', in my 4x4. Had me scratching my head until I asked the local radiator guy if he had any suggestions. Found it with a compression test, it had over pressurized the cooling system and blew it all out the reservoir overflow, several times.. No coolant found in the oil and the engine overheated at least once. Replaced the said gasket, coolant, oil and did a compression test on the motor. The vehicle is still running around 10 yrs later.
If that's indeed what you've done, I wouldn't worry too much. Have a beer and a sit down for a while.

Sounds like a plan.
I would also recommend that if it loses pressure, you listen very carefully to see if you can hear the leak, in the oil fill tube, by the water pump, and in each spark plug hole (through a tube or a hose).

If it were me, 1st test I would put 100psi compressed air into each cylinder (like a leakdown test) while rad cap was off. I will bet dollars to doughnuts that you will find 1 cylinder leaking into the cooling system.
Make sure valves are closed and engine wont turn before you plug the air hose in!

I don't have the tools to do that lol I'm gonna change the head gaskets this weekend it does appear that is my problem but whenever I change head gaskets I do both at the same time
#98
In the near future I would think about doing the timing chain as well

Changing the head gaskets is probably a good idea no matter what in your case. Years ago I, being an idiot, badly overheated my (aluminum head/cast iron block) engine. It ran well enough afterwards, but I suspected that I'd damaged the head gaskt and/or warped the head (eng had ~ 80K miles). Yet, it still had good compression and a leak-down proved OK. So... I let it be. However, the gasket did fail about a year later, and when it did it pumped coolant into the oiling system (I was lucky to catch this before it wiped the bearings and/or hydro locked on me).

REALLY white isn't good, but they may actually be okay.
I agree that it's good to pull the valves and check the guides and the seats while you've got the heads off, but they may be good to just put right back in

To elaborate: A cylinder (and valves) that is taking in water will look unusually clean (and deposits on valves may be white).
Very white exhaust valves can also indicate excessive heat, usually from a lean mixture.

Ok seals are replaced and heads are torqued down to 70 foot pounds got too dark so I couldn't finish it. Anyways leaving it sit over night and tomorrow morning gonna go out in the morning and finish torquing and installing everything else hopefully I have a runner tomorrow afternoon
