TUTORIAL How to Grind Valves and Valve Seats

I always use a serdi machine and it's got a vacume punmp to show that the vale and seat is sealing which works well. It's good to see that you are interested in this type of work

ah, yeah that works too, i was never good enough at it to be sure with blue, but i can see how it would work

I use bearing blue to show how the contact pattern.

Well race car engines only need to run properly for a day and can be pulled down and worked on. I like an engine to at least last it's waranty.

the shop i worked at always lapped the valves in, its personal choice really, i liked it cause it shows the contact pattern well.

you didnt cut them deep enough... unless you get rid of the wear ridge its pointless to grind the seats...

Word of advice. Vice in U.K.

nice job
i need 2 know the name of this tool
it`s fantastic

Word of advise: Vise.

I hope your are thousands of miles from me
a bad amateur!

shows a lot about your perents

Pretty sloppy and careless work.

very nice video man

i dont remember the brand. we just had to do this for school. we used their tools. i think they were called neway.

Don't worry, the video was just fine. Maybe miniman works only on lawn mowers. Racers have been lapping valves forever. What is the brand of the tool.

Sorry spelt it wrong,its called synchro seating. I've been doing valve services for over 20 years and still beleive its the most accurate way of doing it.Aso I have never lapped a valve in a seat in my life.What do you use to set the tappets after the job is done?

yeah i know, we did this as fast as we could. it was an end of the year project.
the barrel was in, you just cant see it.
and no i havent heard of that

that's the roughest way to cut the seat. you didn't even have the barrel in a vice so it wouldn't move. heard of sincro seating?
