Valve Lapping with Air Assist

[HeyLanny]

Thanks for the video. Great. Just wondering though how you are going to be finger printed now after holding those valves in? ;)

[UnderseaCaveman]

@EntomologyPurdue LOL.....yes...but, I do consider Newton's Laws and such!

[R1Kyle]

You could not pay me to hang a drill off a valve stem like that.... At least not on my own engine.

[tiletrader1]

Music was so cool i watched it twice---I'm a little out of my comfort zone when it comes to rebuiling heads but with "High Roller" rockin in the background I just might pull this off... Oh and thank you for sharing this video--i really appreciate it!

[CUBEoneVX]

Sounds like Robocop lol

[PGXI]

not sure if this is good for the valve guides ....a high twisting  rpm might create wear..nice job on the video though

[UnderseaCaveman]

@PGXI The head is still working fine....2 years later.

You make an insightful point, it's worth comtemplating (obviously someone could do the math and physics on it).

[petros172]

how do you check the valve and valve seat with the permanent marker?after lapping the valves i use compressed air and petrol to check for leackage

[UnderseaCaveman]

@petros172 actually not "permanent marker", but rather a dye (perma-blue).....but your method sounds good, I'll have to try next time. Mahalo for watching.

[antonyr123]

song reminds me of title screen music of a old game i played GTA 2

[UnderseaCaveman]

@antonyr123 "High Roller" by Crystal Method.... cool

[batboyboogie]

Actually it's no use to show the seating area on the valve right after lapping. It then always looks like it's touching all around because tiny gaps are filled with the grinding paste, so they are ground but will not touch when both valve and seat are thoroughly cleaned. I mark it afterwards with a permanent marker and then check in clean conditions. Then you now if contact is ok when all is clean.

[UnderseaCaveman]

@batboyboogie true, good comment, thanks

[batboyboogie]

@UnderseaCaveman haha ok I was not trying to be nosy or something like that...just like to think about things and then share it ;)

[chr1s88blue]

and doing this will give it a perfect seal?

[UnderseaCaveman]

@chr1s88blue YES

[donnienall626]

I use this method except with a battery  drill and lower RPM

[UnderseaCaveman]

@donnienall626 cool......the way to go.......happy valves

[mickeygovender]

Doesn't This Method Screwup the Valve Guides.To hold the Drill 100% accurately.Use a suction cup tool for the drill in the other side would be more effective.

Thanks for Your Sharing Experience with Us!!Helpful

[UnderseaCaveman]

@mickeygovender --No, the valve guides can take the minute stress ..

The reason I could not use the suction cup is because of small pits on the face of the valves (no suction, vacuum bleeds off...no seal with small pits).

The valve guides were new as well, so there was no play in the stem motion laterally. Aloha, UC

[mickeygovender]

@UnderseaCaveman Was wondering what do you use to clean carbon off your valves.

[UnderseaCaveman]

@mickeygovender I just used a wire wheel (or wire brush)

[mickeygovender]

@UnderseaCaveman I had loads of Carbon on my Valves&Stems.I put all of em into a plastic Container and used Lemon Juice and Battery Acid.The Carbon just fell off in the morning.I tried Engine Gunk,Wire Brush,Parafin and the ol Coke Method but they didn't work.Maybe this might help someone in the same predicament!!

[UnderseaCaveman]

@mickeygovender That's a great tip.....Mahalo!

[StreetLethalRacing]

@mickeygovender I wouldn't advise someone, especially the newbies who might be reading, to experiment with battery acid. If you want to remove the carbon from the intake valves, as well as the tops of the pistons and combustion chamber themselves, just run some methanol in your running engine. Those who run turbo chargers know exactly what I'm talking about, as a little alky injection (methanol) will make your engine parts looking brand spanking new....

[mickeygovender]

@StreetLethalRacing Theres a Difference Between Giving Advice&Sharing Your Experience m8.People Do Have a Choice.

Thanks For Sharing Your Experience.I will give that a shot.Do u think methanol will loosen stuck piston rings by any chance.Thanks

[StreetLethalRacing]

@mickeygovender Stuck piston rings? Just pull the spark plugs and squirt some WD40 into the cylinders, give it some time, then turn the engine over by hand. As for what I mentioned earlier, always remember that there are kids reading this, and that is why I wouldn't recommend using battery acid. I'm sure it works, but just be careful....

[ted850760]

@mickeygovender pore meth in a cylinder and let it set and I promise it will etch the cylinder wall...not a good thing

[kenzo5716]

@mickeygovender I use Easy-off oven cleaner. Ever try it?

[mickeygovender]

@kenzo5716 is it in uk

[kenzo5716]

@mickeygovender I do not know. I don't live in the UK.

[mickeygovender]

@kenzo5716 Everythings crap here.We have to import freakin most things

[kenzo5716]

@mickeygovender The powers that be are doing the same thing to the USA. Any country that gives away its manufacturing might is run by TRAITORS!!

[mickeygovender]

@mickeygovender I'm gonna try this!!Good Tip.Gotta use some compund though and a level surface.Got New Guides as well

[lesterclaypool1]

are you using a cutting compound ? and should the springs be replaced with larger ones or do you loose  enough metal to care about ?

[UnderseaCaveman]

@lesterclaypool1 Yes, I am using lapping compound. The metal loss is not great enough to warrant heavier springs.

[lesterclaypool1]

@UnderseaCaveman very cool

[ed563]

good choice of music for this vid

[wed3k]

if the valves have pits, they need to be remachined. there's really no way around that.

[bosnabob]

Pits on the face, so the suction tool wont stick all that well.

[UnderseaCaveman]

bosnabob,

Exactly, so I turned to "driving" the valve with an airtool from the other side.

[LLCoolPass]

i find it interesting how many mechanical [on their own time] people are also able and tend to understand world issues and the NWO and you know that stuff. it seems the hard work and deep thinking necessary for that translates into the other stuff

[UnderseaCaveman]

LL,

Agree, I think that Mechanical Thought requires a certain Logical Discipline ... or else "shit just don't work"... you either do everything "clean and correct" or shit blows up in your face (and I have had plenty of that happen to me...LOL). Like you said, that same logical discipline then translates into other observations like "Geez, I wonder why we have INFLATION...follow the money to its logical conclusion".

[LLCoolPass]

Right. You know, it's like this, you see immediately with any amount of studious effort in understanding something like the economics, and you ask yourself why are they doing htat, or say that is stupid or that doesnt make sense.... but after a while, you stop thinking you're smarter thanthe people running hte govt, you learn to say ''who benefits' because you treat it not as innocent mistakes but as purposeful scheming and criminal activity. btw, I recently changed the head gasket on 3vz-fe

[dstick1]

LMAO, I remember using the hand lapping as a kid, geee what an exciting arvo in the shed that was with Dad....:) I like your method when there is no child labour available LOL!!

[UnderseaCaveman]

LOL... yes, child labor is awesome... I did plenty of that (under Dad's Command).

[LLCoolPass]

yeah but how much high end torque you are going to use living on an island? lol :>

[UnderseaCaveman]

LOL....really short period, then car is amphious :D

[LLCoolPass]

yeah really. i mean, i would find a way to get off the island if the shit hits the fan. its just one big prison, really. a car that doubles as a boat is wonderful.

[UnderseaCaveman]

LL,

Funny, you should mention "if shit hits fan, just one big prison"... I was having that discussion with someone else on Island. I was advocating staying on Island, the people really do well here when shit hits the fan. When we had our Earth Quake a little while ago, and Island lost power for 24hr, nothing happened, no riots, no looting....everybody managed the 4-way intersections (traffic) politely and in good order. But having a boat to "get away to smaller island" is very good.

[LLCoolPass]

dude i know you just said that to lift your spirits in spite of the the deeply disturbing truth you know. i stand by assertion, and i think you know why I'm laughing at what you said. if not, if the case is that you're puzzled, well, i like you, we're internet friends, so of course i will explain if needed. but, i think you of all people know at least some of what i do about this.

[LLCoolPass]

but for anyone else,

after 6days of no electricity, things change

after 3 days of little food, things change

in a REAL [not the media pursued swine flu bs] pandemic, things change

in an insurrection/rebellion, things change

an island that is only run by having massive imports to keep it going is even scarier. a real test of darwin's sick theory that will be.

big place like the states along the gulf of mexico, things went really bad. type in Katrina in a search engine

[UnderseaCaveman]

LL,

Qui... I know (deeply disturbing possiblities).... in that kinda shit, I just want to get to Molokai...lots of hunting and fishing, and good island (ocean) people..

Agree, a Darwin Test ...and something I would like to pass (with at least a "C", if not better). Yeah, the answer would be "Escape to the Country" (the woods, the backwaters, etc.).

[LLCoolPass]

its not 1850 dude

you have no escape, the first thing the guard does is secure major travel pinch points, and they control the waters

there are a lot of people, people will even swim to the various islands that make up your state. you're all going to be competing for extremely limited resources. you have over a million people, and if I had to guess I would say HI makes it impossible to have guns, to carry them legally is probaly not allowed either...so... only the crooks and/or militar will

[LLCoolPass]

befriend someone permanently stationed there, in your age group, in the military or national guard, if you haven't already, might be a good thing until you actually decide to leave that death trap. HI on its own is agreat place to live, maybe 150 years ago when it was a kingdom and all that jazz, 1million people and huge military later, and de-arming of hte populace later.... if i were you, and i might be misguided about laws there, i would get weapons even if illegal, just be careful to hide

[UnderseaCaveman]

LL,

Concur....I have been thinking about the Plus 1 million on Oahu....and if "shit happens"....there will lots of STARVATION.. In Fact, OAHU represents the "most isolated plus million people in the world"... I have other escape plans as well, like outer Marshall Islands or Palau and the like....depending on the degree and weight of the "shit".

[sunny5rising]

Great video. I used an electric drill on mine. Either way sure beats the hand lapping tool.

-Sunny

[UnderseaCaveman]

Sunny,

yeah, the hand lapping is a bummer...with drill sooo much better.

Aloha, UC
