well me and my buddy were changing valve springs to put on some 1.6RR, we did 3 springs without any problems went very smooth, i was using the screw type compressor and putting compressed air into the cylinder. but here is the problem i believe i was using an air brush compressor. it only puts out like 30psi...lol..when i was puttin the seal on the 4th spring....it went down into the cylinder i was like holy spit!
well since i have to pull the heads anyway. i am going to send them to lloyd for full porting and bigger valve. and better springs and throw in a XE224/230 cam, a little sooner than i planned on doing heads/cam but i refuse to take the heads off for no good reason! but now i get to have 350+rwhp from my "little" lol accident...
for everyone out there do not use a small air compressor to change springs unless you are ready to pull the heads...
actually it only took 2 of us about 8 hours wasnt that bad, but we havent pulled the cam yet, had to go back to work

how come you didnt have the cylinder at TDC?

 

'Cause he was using compressed air instead of the TDC method.

 

yeah i thought i didnt have to worry about the valve dropping, i guess it was a good learning experience.
