did a timing belt, head gasket,... replaced every gasket and seal aside from the rear man seal about a year and a half ago, to solve an oil leak, just ask ill go into that one later, but back to my question. white smoke out the tail pipe signifies water, from either a head gasket or a cracked block or head, but crompression pressures are within specification just more of a spread than i want to see. what do you think the problem is. #4 , i think i made an error in my initial reading, but it is too late now.
#1 158 psi dry, 168 wet
#2 172 psi , 180
#3 170psi, 170
#4 185, 172
i am curious to hear what you think, i get to pull it apart and find out.

a blown valve seal would produce a bluish smoke and i would loose oil. the radiator slowly drops.

believe you me, i did EVERYTHING everything by the book aside from magnafluxing the block. any block sealer is only a temporary fix. i did this truck as a class project for a speed development class. started out as a leak. come to find out that the last gut that replaced the timing belt screwed up, when he pushed the timing chain cover he cought the front edge of the head gasket. i had to tear the engine just about all the way down. as i said befor i replaced everything but the rear main seal and piston rings. i did not service the head but i did measure for warpage and replace the valve stem seals.
this was all done about a year and a half ago. the truck belonmgs to both my father and my grandfather. my father currently lives in oklahoma, so he does not drive it. my grandfather uses it for project stuff around the house,junkyard trips and things of that nature. the frustrating thing is this, my uncle and my cousin, both borrowed the truch for a while, thenm this problem happended.

first off, white smoke represents water in the combustion chamber, blue smoke means oil, and black means excessive fuel. the compression test some what supports this. later on today, i am going to pull it apart slowly and see if i can not find the breach

It is possible the head gasket didn't seal correctly. Also when you did replace the gasket, did you measure the head with a straight edge to check and see if it was warped? What about the block? One way you can check for coolant getting into the cylinders is pull all the spark plugs and put a pressure tester on the cooling system and see if coolant gets in any of the cylinders. You may need to let it sit for a while and keep checking, but it's something you can try before you start tearing things down without knowing for sure. Good luck and I hope this helps. Just for the record, blue smoke is oil, black is fuel, and white is coolant.

Intake manifold water jacket seal leaks and sucks water into the intake when the cooling system pressurizes.
Pull each spark plug and see which plug is funny looking.
They make cooling system sealant that may work great.
"Bars Leak" is my favorite. Bottle is beter than tablets.
Stay away from "alumaseal" it sucks.

the valve stem's rubber seal. is broken.
my wild guess, the number one cylinder.if You don't replace that seal soon, it will burn the valve seat .
white smoke is oil.
bluish smoke is water.
