Changed out the valve springs

The job took about 7 hours with specking the lifters and doing compression checks on each cylinder, glads that over. With the neat air pressure tool my friend had, we're were able to change out the back of springs all at once without having to worry about the valves dropping in the cylinder.

Even though the engine was rebuilt. I had let it set too long with turning it over to work the springs, so some of them were under full compression and thats not too good for them.

It might be, the mechanic I barrowed it from uses it all the time at the dealership, it has two sizes of threads (I guess the most common sizes). It seems to be based on the same principle of the single hose model. Seems simple to make, all that is requires is machining and tapping a block. Picture on left is from the 'net, the one on the right with the 4 black hoses is the tool he let me use.
