I'm going to plug this into my cnc mill at home after I finish the engraved oil catch can.. may as well sell em to those who want one (after i've made and tested)
the degree marks are the cam degrees - not crank
so the 13 degree retard people like to do is 6.5 cam degrees
this is really just a preliminary design till I get some more measurements I'll be redesigning it to allow adjusting screws to apply force to the cams to adjust them with the crank sitting at TDC.

redesigned - there is now a 3/4" hex to put a wrench on to adjust the cam timing its currently adjustable up to 12 degrees advance or retard.. (24 crank degrees each direction)

I was checking these out and i would have to say go with the second designs cam timing referance marks versus the first design. The first design might cause people to inadvertantly change the lobe separation angle by adjusting the cams in differant directions to get them to line up to the same marks on the middle scale .

alright I got the measurements off the engine today and modeled it up -
this is now the latest design - its been priced for production and can be ready in 1 month I may start a pre-buy to get these done asap if I can get people interested at 75$ with free shipping
I will be milling the prototype next week for a test fitting before ordering a production run.

i'd be in too. response to what you said at the top. yep, cams move at 1/2 speed of the crank. 1 suggestion, since the 6.5 will be the most popular use of your tool, put a 6.5 specific mark on it.

no payments yet - not accepting money for pre-orders till i have tested the function of the prototype.. I'll update this thread with all the info as it goes along - sittign here watching the mill run as i type so I may be testing this weekend..
any tips for getting the cam pulley bolt lose? I'm still waiting on my aircrompressor from harbor freight so i can use an impact gun on it - bolts are tight turning them is turning over the engine

I made the cam holding tool, stil turned. I nthe end I used the impact gun. 30 seconds and they were off versus 2 days of messing around with the 'correct' tools.
maybe im just unfamiliar with the 3.4 but how does this tool work?
the cam pulleys on the 3.4 TDC are not keyed.. they are essentially just held on by a bolt.. so to time the cams you have to set the crank at top dead center and use a tool that holds a flatspot on the cams in place then tighten the bolts again.. this tool allows you to set degrees of advance or retard before tightening that bolt.
just a little update with something prettier after engraving and painting (the production version would be anodized not painted) I'm currently figuring out how to flow a bright pigment into the engraved degree markes..

Unless i get around to it sonner it will be getting tested next weekend, and pending any revisions would be available for sale a month after (after a successful testing i'll be accepting pre-buy orders, but not untill I know for sure the design doesn't need changes)

Alright guys - I decided to relocate the timing marks to the top to make it easier to see while installed the production run has been ordered and they are up for pre-buy sale at www.viscoustech.com
estimated shipping date is the first weekend of march
