Great video. Happy to see someone using high quality Mitutoyo measuring tools. Too many people out there using interior measuring tools thinking its good enough.
Hope your machine guy does you a good job. It's nice to have a narrow seat as it does seal a little better but as long as it's all concentric I would not take a chance with machine shops. Concentricity means everything over .010 or .020 over ideal width. With turbo and nitrous exhaust should be a little on the loose side to keep from hanging a valve anyway
The contact pattern on the valves should be at the top, next to the valve front. Your pattern was at the bottom. Which indicates the valve seats need a recut.
@@HTMR Thanks. I haven't used one before so this makes more sense now. I was oiling the valves before inserting them back in the guides but noticed the play would only show when I had wiped the oil off the stem. Can you confirm if you should be checking them "dry" or not lubed? I guess not lubed would simulate an operating engine better because the oil seal would wipe off most of the oil.
The taking a measurement from the edge of the valve head using your Dial gauge doesn't seem very satisfactory to me. You started to hit on the reason, but maybe be best to avoid that technique altogether, methinks. I like your vid, much appreciated.

Marker only your seat then spin the valve.
Not both

Why do you use the bore gauge on a bit of an angle rather than parallel with the valve guide? Does it make it easier to remove?
You insert on angle, lock it down, then go parallel to have it conform to bore diameter.

well explained thx man
Hello mate, is it ok to use water as a medium for testing valve leaks?
What would you recommend the best way to test valve leaks, thanks
i usually put petrol and flip the head to see if the petrol is leaking from the valve seats
HI COULD TEL ME HOW TO AJUST VALVES ON 8N FORD TRACTOR
8 thousandths /2 = 4 thou clearance??? That not how geometry works...
Dial indicator with magnetic base - amzn.to/3iWOLph
0-1" mic - amzn.to/3kGujJL
Snap gauges - amzn.to/33Qrm2B
Calipers - amzn.to/2RTdDTc
Looks like a Ford head, LOL Wait the LS is Ford designed.
