i dont have step by step pictures, but i doo have some
i followed the chilton book and took out the rad/condencer as well , what a big effing wasit. oh well
heres what i got
air intake ducting, fans and all hoses undone. rad drained out, belt off
close up of water pump,, crank pully off, rad/condeser out
coil and smog pump removed *found that a shallow 9/16's and an extention worked really well to get at the bolt behind/beside the a/c, worked soo well the socket is still on the bolt as u can see
*
water pump off, dirty failed opti exposed
opti off *mines a 94 and it has the splined drive. if u look close u can see a yellow mark where the flat spot on the spline is. made it a lot easier when i put the new msd unit it. had an idea of where it should be and it just slid right into place. no force or love taps*
all ive got for now

If You Guys Are Using Original Gm Or Aftermarket Optis, Take A Look At The Connector Housing On The Non Vented Versions. You See A Small Bead Of Sealant That Seals The Gaps In The Opti. This Small Amount Of Sealant Will
Fall Apart In Very Short Time. And Allow Them To Fail If Coolant And Oil Gets Inside. Its Always A Good Idea To Add More Sealant To Them In That Area Before You Install Them. And If You Are Doing The Vented Conversion
Dont Forget To Seal The Holes At The Bottom Of The Of The Opti Case. If Not
You Will Be Sucking In Water And Dirt If It Gets Around That Spot Since You Have To Hook Up Vacume Lines To The Cap.

also i recomend (especially for us non vented guys) that a step be put in, that step consists of after attaching the opti plug in all wires and connections and start the car and rev it a few times to make sure that the opti is installed correctly. (just not for too long, you dont want to overheat)
