How to Clean and Refinish Valves
We going to show you how to restore a valve that you have for your engine and make it look brand new again, so I'm in the middle of working on my cylinder head and I'm almost done the porting and polishing procedure now I do have a video coming out for that and it's taken quite a long time because it's a lot of work and a lot of man-hours that are being put into that but I wanted to give you guys a video in the meantime and let you guys know what I'm up to.
So in today's video I'm gonna show you how to go from a valve that looks like this that's disgusting corroded and covered in old oil and carbon and I'm gonna show you how to make it look like this where it basically looks brand-new so the process is quite simple you don't need a lot of tools for it and the results speak for themselves.
Now in this video I mean working on the valves from my Mini Cooper motor but you can apply this exact same thing to any kind of valves that you're working with so it doesn't matter if you're working on intake valves or exhaust valves this concept is the exact same thing so I'm gonna first show you the difference between the two and I'm going to show you how to get that done so.
These here are two intake valves so this guy right here is the one that's covered in carbon and it looks disgusting so this does have a lot of kilometers on it it has to be more specific and this one here is the exact same valve as this guy but cleaned up and polished and you can see it looks great so it doesn't matter which way you look at it it looks better from every direction so this valve right here is what's happened after a direct injection engine has gotten to it and it's done it's damage for kilometers.
Now beforehand I cleaned up this entire valve and remove the large pieces of carbon that were found on here and you can see that there's a good amount of stuff that's found around the outside perimeter of the valve and that right there is what's actually making my engine have an improper seal there are gonna be two different ways that you can make the valves usable again.
There's gonna be a quick way and then a more professional way I'm going to show you how to do both of those should you want to choose between the two so I have right here a tray that has all the components to my cylinder head now if you look on this line right here this is all my intake valves and this line of valves right here is all for my exhaust you can see that the first four look great and the back four don't quite look so good I'm gonna show you how to make these ones here look like this so to begin I'll be using my Dewalt drill and installing each one of these valves into the Chuck of the drill now the reason.
Why I'm doing this is because I can make the entire valve spin on an axis and then all that I'll have to do after that is grab either the sandpaper or the scotch-brite and just hold it on the valve so you can see how easy it is to actually remove all the dirt to build up in the imperfections on each one of the valves now depending on how dirty it is and how complex it is you might have to just clean up the vows first with a little bit of degreaser but if it's just a light amount of dirt or a light amount of buildup you can remove all of it just like this so doing it .
This way will get you by and this is what most shops will do when you're just gonna have to get the cylinder head refinished a little bit they're not gonna go to a crazy extent to go ahead and polish the valves all that they're going to do is this process right here now this is good this did remove most of it but we can make this a little bit better now if you do care about your engine this is the prime time to get this done so at this point you can see that it does look pretty good all the carbons removed but we can still make this.
Look a little bit better you can see by comparing it next to an older valve you can see how much crap we've removed from the valve itself so if there's any more carbon that's on there all you're gonna have to do is turn your drill on hold it a little piece of scotch right there and it will do its thing you're not gonna want to do the work itself you're gonna want to let the drill do its thing so just hold the piece of scotch brite wherever it needs to be and all the carbon will come off .
The valve that I have here on the left is after I've polished it and after I've made it look good the valve on the right is only after I've used the scotch brite now it does look pretty good but we still can make this look a little bit better so for the next step I'm gonna be grabbing a bowl and putting a little bit of water in it and you'll see why the reason why I'm going to be doing this is because for the next parts what we're gonna be doing is when you wet sanding the valve I'm first gonna begin with an grit piece of sandpaper and we're gonna do the same kind of process as we did with a scotch brite but,
Instead of the scotch brite it's sandpaper so this is gonna be removing the heavier imperfections and the scratch marks that we embedded while we were using this scotch brite so with the valve inside the drill just turn it on and let the sandpaper do its thing if you can keep the valve along with the sandpaper completely submerged in the water we're not going to have any dust that's going to come off of the valve and we're not gonna have any dirt or whatever that's going to be airborne .
When you do it like this the sandpaper also lasts a little bit longer so be sure to get the stem be sure to get the bottom and be sure to just get every single part of it so that everything gets sanded and is nice and uniform after what sending our valve with our good sandpaper we can see that we've got a nice finish and it looks like this if it doesn't look like this you're gonna want to go back and keep using the grit until looks .
Really nice and really smooth so at this point we've got a much better finish than just the scotch brite but if we want we can make this look even better now to do that we're gonna be going to a higher grit sandpaper and we're gonna wet sand it again I'm gonna be using grit and then we're gonna keep working our way up until we get to our polish so just like before....
