I have a 87 iroc 350 tpi when i start the car a puff of smoke comes out of the tail pipes, someone said this was my seals on the valves that were leaking...they gave me a diagram on what to do and how to do it....i would appreciate it if someone would put that diagram back on, the file i saved it to was erased and i wanted to get this done before i bring it out of storage, thanks for your time....

 

Valve stem seals. common occurance on SBC engines with over 50K on them.

 

can anyone else send out a diagram of the work that has to be done....thanks there was a nice pic on here about 2-3 months again

 

heres a not too detailed list of what needs to be done:

-remove valve cover/(s)
-remove rocker arms
-buy the fitting that screws into the spark plug hole to inject compressed air into the CC to keep the valves from falling down.
-inject CC's w/ ain
-use valve spring compressor to remove the spring and retainers
-pull off the old valve seal...install a new one
-put valve spring back on/install retainers.
-after your finished you must adjust the rocker arms

you can only do one cylinder at a time,which means,2 springs at a time.

ive done this before,its not very hard if your mechanically inclinded,but its just time consuming.

 

Thanks for the help....what are you looking at time wise to do this? and i am mechanically inclinded, but i have never done anything with heads, how do you adjust the rockers? thanks again

 

Whats Shot Is The Valve Stem O Ring On Top????right?????

 

whats shot is the round seal thats about 1/2 inch to 3/4 of an inch tall,wraps around valve stem right where it comes through the valve guide on the cylinder head.
