parish you are going to fill the cylinder with air then take a say 14mm deep socket and place it on the retainer then pop it a fiew times with a hammer. this will break the locks and retainer loose.
i would call the factory and ask when they rate them at .6xx lift what there settup tollerance is. in my case the springs were rated a .590 or .600 and running them so tight with .591 lift was killing them.
like slow said they normaly set them up at around 1.800-1.700. hell now that i whink about it i dont think mine were in the .700's i realy dont remember though it was too long ago. i did write it on the retainers though for next time.

if it is a setup issue then this will not be the last one.
good luck

 

by cap do you mean retainer? if there's nothing holding the retainer/keepers up on the valve then it should fall...unless there's something more fukt than meets the eye.

 

The retainer and valve lock can get stuck on the end of the valve. Its not uncommon to have to tap them to breal the locks loose.

 

yea and i have only had it happen when i broke a spring for some reason.

 

i am not sure what these parts are called, i guess it is the retainer and locks.

there is nothing holding them up, they are just stuck, not sure if there is something more messed up or not. rocker looks ok to me.

 

the only other thing to check is the valve stem seal. it depends how long it was ran like that. everything else should be ok since you said the valve still sealed.

and the big round thing that is shiny is a retianer and the things that hold it are locks if you were not being sarcastic.

tap it like i said and it will come off. i use a socket so you are not hitting the retainer on one side and messing it up.

 

Were the springs heat cycled? As in did you get the engine running to operating temp, then shut it off and, once it was cold, do it over?
Or did you go for some street kills right after installing the springs and cam?

 

ahh, i dont remember, it has been a few months, these things really should come with instructions if they want you to do stuff like that.

 

When you do get it off, are you going with all new springs? The comp 978s would be cheap insurance for all the $ your puting into the engine.

Tough break though, sorry to hear it.

 

this is a cheap motor, not the high $$ one. trying to save my pennys for a killer 409, probably just swap the one spring.
