Your right your suppost to either change the valve or use a tube of some shit like sand paste lol forgot the name and grind the valve on the seat for about 15 min straight left and right , Then it will reseat the valve we did it on a single cam neon engine. But the exhaust and intake have to be the same just not same order aslong as you use the sand paste thing (ill get the name of it tommorow) to reseat

Horrible news, I didnt keep track of what valve from what section. So what.. just need new valve seals and not a whole set of new valves as well?

dont use a paste and try to regrind valve seats by hand. very bad juju. have a machine shop do it. it might not be in bad shape. but heres the trick. always etch the valve face with a number straight up and down so you know which guide and seat it went in and which way it was oriented. and were not talkin about valve seals. you probably shouldve had those replaced too while you had it apart along with the guides. this is why head work can get a bit tricky, along with any internal work if you havent done it before. if you are really going to build this motor, i would take it to a reputable machine shop that is very good with honda heads. have them put in new seats, guides, liners, seals, valves, and maybe work in a bit of a 3 angle or 5 angle valve job, and a p&p. if youre going n/a youre going to need all the help you can get moving air through the head and those things will help. the head work without the valve job and p&p should run around 300 bucks. the p&p and valve job will vary depending on the method the shop uses. cnc p&p jobs are about the only way to go if you want accuracy. they hand do one port and a cnc machine copies it to the rest. valves arent that expensive if you stick with a stock valve. ive seen nitride valves for the d17 but theyre way overpriced. i would find stainless if you can, just in case you ever want to spray nitrous or anything, but stock valves are fine.

yyou can use the paste and grind method dealers use it so why not? the only thing u should change are all the seals thats a must. andlike that guy said take it to a shop but i recommend getting the arp studs i belive and working on the head ugh i gotta pull out my engines workbook to see what measurments and procedures i did on that neon engine. ill get back to u ASAP

[_unclejuice]

not being an ass but this isnt a neon engine. all engines are different. i rebuild atleast 2 engines a week. if you dont know what youre doing, take it to a shop. dont think you can get a book and know it all. you shouldnt just change the seal unless you want to half ass it and then be posting in a few months because your engine is fucked. arp studs wont be of any use to him if hes staying n/a. and again, dont try to regrind old valves by hand. get new valves and take the head with the new valves to a machine shop. tell them you want them to install the new valves with new seat, guides, and seals. they will do the rest and mill the surface flat. if you half ass this, youll be doing it all over again shortly and it always costs more the 2nd time after something has fucked up. trust me.

ahhhh damn you had all that shit in baggies and lables but not the valves....I remember when I was like 16 my mothers boyfriend and I did a rebuild on his jaguar v8 and we used a box for all the rods/studs/valves/whatever the fuck was in that thing lol. We numbered everything and it made it basically like putting a puzzle back together with the picture to look at. Now 9 years later and I don't even feel comfortable taking that shit out of my car. Then again, mine is a daily driver.

"paste and grind method"???

Ha!

It's called valve lapping, boys. And it's an effective way of fine tuning the seal between your valve and seats. I've used this method on engines long before UncleJuice started his weekly engine building blitzes and I've found it to be effective on Honda heads that were in decent condition. You can test how well your valves seal simply by pouring some liquid in the combustion chamber with the valves installed after you've lapped them.

Head building tip #453.

When reinstalling your valves do it in a small room and put a old bed sheet on the floor so when your keepers go flying across the room you can find it in a few seconds.

Thanks Triz for the DIY. Good luck with the reassembly.

I wouldn't say it's not recommended but possible not necessary if a machine shop precision cuts the seats and you are installing new valves. Otherwise if you are doing your own rebuild on a head that's in good condition, it really helps in reforming a good seal.

Allright, so I never heard of any of this paste and grind method, or lapping as its been called.

SO I still have the head apart, been busy, aka lazy, and havent got around to this.

Head is still apart. I got my gasket pack and valve seals today. Need to consult the bible for the trick to getting them out- a set of pliers seems very wrong. So I get the valve seals out (the things with the spring around it) and this is where I have a question. Do I need to get valve guides as well, and anything else? How much do these guys run.

Also I am thinking about pushing the install date back as well and picking up new valves as well. Comments on .5mm and 1mm oversized valves? Comments on the stainless/ vs coated

I'm looking for aprox. prices on what it will cost in parts for whatever else I need aside from the valve seals I already have, and the valves I will be getting. What else will be needed like valve angleing or anything that I shouldnt be able to do myself? Also whats this on the 3 or 5 degree angleing job? Prices on having the machine shop hook up the head to run the oversized valves as well would be helpful.

I am def keeping this in my favs. When my second source of income comes in I will get another head and rebuild it, then drop it in the car. For now I will be doing nitrous so I dont look like an ass trying to pass ANY car on the highway. Living on your own in NY FTL!

PS You should do another video of you completing the job and dropping it in for those that have never done a ....head job, before. I know its pretty straight foward putting it back together but trust me, for people that normally don't do these things, they will feel ALOT better seeing it done first

Just my 2 cents.

Triz you might like to take a look at this.
