Lapping Valves the Easy Way

[danielberto]

Been using this method for over 27 years

[craigtimmons]

So what happens when the lapping compound is burnt out of the pits in the valve face?

[joeljarg]

Eso es un trabajo que se hace manual para que quede perfecto, no con taladros

[agungdecaprio]

Already I do.in myplace we call "skurr 👍

Ленивые любители шуруповерта. Вращать нужно руками, в разные стороны с отрывом от седла. С контролем результата.

This is total bs. Let me tell you people never ever ever use mustard on valve stems. It has no place in the shop environment.

[СергейКривенко-ьх]

🤦‍♂️👎 Фаски на седлах надо поправлять!!!!

[thastinger]

Probably charged for "a 5 angle performance valve job with valve back cut"

I still have my red wooden dual suction cup tool.
They were opposed to using valve stems to lap.

[waynetalhonda]

Thats not a good way to do it scoring valves and seats easily plus it can make the cut concave

[heavymetalmechanicX]

Step 1: Spread mustard on valve stem.
Step 2: Procede to ruin valve and seat.

Éso se hace desde tiempos anteriores cuando el rectificador se evitaba porque el cliente llegaba al taller diciendo:...
"Quiero que le hagan una descarbonizada a mí coche" y lo hacíamos manualmente como en el video, pero ahora se ahorra tiempo al llevar la cabeza (culata) al rectificador en lo que hace uno otros trabajos... 😅

I used additional valves ground at 30 and 60 degrees to allow me to narrow the seat or move them in or out till i got a sioux valve seat grinder kit

[andrewandrejcisk]

Thats a really good way to get grooves in your valve seats....

[Nikolay_Kopytin]

Пятно контакта слишком широкое надо седло подрезать

[jesusyeshuaelelyonelshadai]

This does work u need to lube valve stem good and use a good silicone hose with drill

[BenVanAmburg]

I miss hand lapping valves when I was back in school

[EVO_IX]

Stupid question? How you know when to stop?

[foxisthebest]

just ruined a good valve job. if they were cut right in the first place
