buzz test and Contribution test ran

the valve spring has a cap on top of it that the valve keepers slip into and it holds the valve into the spring.. if the cap broke like that it would have probably caused the keepers to fall out too and the valve would have fallen into the engine now if the cap only broke part way it might be still holding the valve just barely... which would be a dangerous situation in the future when it finally does go... (valve dropping into cylinder and hitting piston at speed).
If it is the valve spring cap then you could compress that cylinder with air and you could actually remove the keeper and cap and replace with a new one without taking the head off... but the cylinder needs to be pretty tight to hold the air cause if it doesn't hold the valve will drop and you will have to pull the head then...
This is all from a perspective of a gas engine repair... pretty sure it will work on a diesel as well...

yeah, could only get about 250 on the gauge but was doing it cold too. Everything else looked ok to me , but that it not saying too much considering I am no engine man by no means. I did a leak down test with the 4 cylinder up to top and wouldn't you hear air out the pipe or out the oil fill if the rings were leaking. I couldn't really hear air from any where except right where I was plugged up to the gp hole. Also no bubbles in the coolant. Man I am so damn upset that the valve seal wasn't the culprit......

yeah, I am too the point where I am just fet up with it and may just break down and take it to someone. Gonna have to drive it like it is for a bit though due to being poor for the time being and another lil one on the way. Just sucks cause it fired right up after sitting for like 3 days and runs really strong, but just puffs this damn blueish gray smoke on light acceleration and take offs.
