installing vinci dual springs, hardened pushrods and yella terra 1.85 rockers
started last night. removed the strut tower brace and engine cover
next up remove the coil packs
the rear bolt for the passenger side i used a 10mm gear wrench
to make the passenger side easier, i removed this 10mm nut holding the line that is over the coil pack
next up is removing the valve covers, rockers and pushrods. 8mm bolts hold the cover and rockers to the head. after that, remove the spark plug wires and plugs. 5/8" socket for the plugs.
take a brass type hammer and tap on the spring retainers to break the oil seal on the valve locks.
now install the vinci dual valve spring tool and cylinder air hose. the compressed air will hold the valves up while swapping the springs.
close up of the spring tool on the head
compress the springs until they are lower than the valve locks. i use a magnet to help remove them
once all four locks are removed, decompress the springs and remove the bar. remove the sprigs and retainers. now to pry up and pull the valve stem seal/spring seat combo off. i used a flat blade screwdriver and wedged on the seal and spring tool.
here is the oem valve seal
here are the replacements
with the spring kit, it comes with spring seats and valve stem seals install the seats and press the seals on until they bottom out. do this lightly. i used a 13mm socket and hammer to seat the seals
now put the springs and retainers on. use spring tool to compress the springs low enough to install the new locks. once done, slowly decompress the springs, ensuring the locks fit into the groove on the valve, until completely off the spring.
now 7 more to go
