- Measuring PTV, Tool Suggestions, Pics? -
I have a ported 14 head that needs installed on something, lol. I would like to be able to measure PTV clearance after assembly. Jim told me to use a magnetic base dial indicator, and I was wondering if you guys might have some pics of your setups?
I did a search, but it is hard to find the exact details I am looking for.
Also, suggestions for a quality indicator and mount would be great. I only want to buy the tools once, if possible. 
Thanks!
Shane

I searched your posts, and Tim Chins....without any luck...maybe I will have more time next week....but the search engine leaves a lot to be desired.

Shane any basic dial indicator and base will work. Buy something cheap. Then you will most likely have to make a plate for it to sit on. There was an old thread on here a while back using a ZX12 engine with pictures.

I love quality tools, so I would like to get something nice that would last until...well, until I don't need such tools anymore. Still can't find those pics...

I think Karl posted some pics in here(about half way down the first page). I can't see the pictures at work. Take a look and let me know if they are the right ones.

Nice:
quote:
OK time to do PTV
i now have 2 patented TimChim Valve Spring compressors AND a new McM-C jointed dial inticator base:
a close up:
the useful Garage Barbie shit-canning my old magnetic base. The new jointed arm one KICKS ASS!
i could only get to exh CL 104.6 @ .056" PTV
(CAUTION do NOT set yrs this tight unless you are REAL sure of set up ..., I'm told that exh PTV @ .080" is much safer.)
I'll send this experimental head back to Y2K for another 15 thou off the head and sink the valves a bit more. I want my CR back to 16+:1 but i want to also be able to get 102/102 CL's. It'll be close...
the song that never ends 
But this gives me wood (although I don't see how you measure the ptv in this pic??)
quote:
Just for the record, the valve spring compressor tool, of which Karl is sporting two, does not require modification of the cam tower or camshaft for proper operation.
Of course, if the ZX-12 had properly-designed cam towers, Karl could use something like this and experience excruciating symmetry during his engine builds:
The only thing missing is part #'s...and do you guys check on each cylinder?? Because it doesn't look possible with these setups??

Shane you will have to take these pictures and custom make something for the 14. These are not store bought items and the 14 head is a lot different from the 12.

Yeah, I think the only things I can use are the indicator and base...all else will have to be custom. I have a slightly damaged head that I can use as a base to mock everything up and test it.

that jointed mag base is the tits, McM-C sells a cheaper jointed model which also works well. I had both and even at $100? vs $20, i'd buy the expensive one again.
tonight i'll set quench on my busa motor, tomorrow determine CR, this weekend set lash, and cam CL's, measure PTV.

ok the easy setup is sillyputty on the piston turn it over with head gasket on but just tight not torqued and compressed. after two turns for both valves going into it take the head off and slice the putty at the valve dent and there is the real clearence.
i am also aware of dan from action maching putting a .060 extra shim holding the valve down that much and turning over easy and slow to see if it hits>(you can use anything size wise that makes you feel safe) we used .060 at the time.

The problem with the clay and the thick shim methods is that they only allow one timing setting per test, and each test requires removal of the head and cams. If you're looking to sneak up on the timing, and you want to do it quickly, then you need something like Karl has shown in his pics. One alternative is to use a light spring under the bucket and use a screwdriver (rounded) to depress the bucket. Note that you will still be required to take off the cams and head to remove the light spring, though...

yes we had my cam at a 108 centerline and with the rod ratio it would not benifit being at a smaller number with a good rod ratio and a long dwell time at tdc. we were just looking for clearence and what kind of lift it would take.

I have the TC PTV tool, it works great, even with 65lb Carpenter springs. Tim even sent me a jointed arm which i promptly broke all excited and what not  the premade probes work awesome though.
i can check PTV at various cam settings and get measurements without pulling the head, checking clay, dealing with light springs ect ect. too easy, once CLs are set, you put on the valve cover and fire it up...

On a new set up with new pistons, ALWAYS use clay to assure lateral valve clearance in the valve pockets, ALWAYS. RBAIN found out the hard way, as have others...

the side of the valve to the side of the cut out in the piston. you may have lots up and down, but not sideways
this issue was do to excessive skirt clearance... but you get the idea

yes, larger valves may require some material removed from the piston
