Default Valve spring replacement.

I will be replacing my valve springs soon. I am going to hook up my compressor with 150 psi, to the spark plug hole. Has anybody ever had a valve drop into the cylinder using that much pressure?

Thank you. Did you keep the piston at, top dead center?

I did not because it depends on what type of "keeper" release tool you are using. I used a spring compressor that does not place any load on the retainer or the valve , I did not spin the crank at all using this type as I was confident that the air would hold up the valve and it was much easier because I did not have to bring each piston up to TDC , See below

But some of the others are like a lever that push down on the top of retainer to release the keepers , if you are using one of those I would spin the crank if you are worried about dropping a valve

I have 20,000 on my new engine so i am probably going to be doing the same soon

Good Luck ,
Dave
