keeping the valves seated, replacing valve springs, seats, ect...
Okay guys, so i have my motor on the engine stand, oil pan is off, the valve springs are off, now just the valve valve seat/seal, and the bottom retainer, I have a leak down test, could i use this to fill the chambers one by one, so i can change these springs seats, seals, and bottom retainer? also i ordered the part number: 12555884 - GM Z-28/LT1 High Volume Oil Pump - Use with .620' diameter, but the driveshaft to the drive gear is like really little compared to the old one and it has no pick up tube, can i use the old one?

I would use a pump like the Melling 10554 instead (3/4 inlet).

Okay so I've done 3 valves now, no issues, pull the seal up take the bottom retainer off and push the seal back on, now that I pulled the seals off with pliers, i can pull them off by hand, and these bottom retainers look the exact same! size and everything, could i just leave the old retainers and seals on and just replace the top retainer, and locks? this would make my life so much easier!

due to timing, and not having any, I kind of need to get this done and out of my garage by next week, so I was wondering if I could just use whats already there?, replacing the seals later will only take an hour or two so can i just use the old seats and seals? literally at this point i am running out of rides to work and school, and my bank account is on E...

I changed my springs and seals with the engine in the car and it only took me a couple of hours. I don't see what the time problem is. Once the spring is off, it takes about a minute to change a seal.
