springs and rockers installation

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

finished up today. overall about 6 hours.

picture of the valve stem seals and spring seats installed



springs on





rockers and pushrods on. make sure to add some thick lube to the ends of the pushrods to prevent any galling on startup.





the rocker kit comes with thicker valve cover gaskets and spacer nuts to add to the valve cover bolts





valve covers on





coil packs back on





crank it up and make sure all is well. no valve cover leaks and major noises not there. if all is well, install cover and strut tower brace and be done.

Nice. You’ll have to let us know how it performs. Always curious about adding different rockers.

i've done this on previous cars of mine. my 99 and 00 formulas, i've installed dual springs and crane 1.8 quick lift rockers. gained about 17 rwhp throughout the rpm range each time.
