I need one too

Would you double up on the gaskets to increase compression? Also, I’ve heard to make both the head and block rough so they “bite” down 🤷🏼‍♂️😂

Thanks!

This is not the way to do it. The head will look very pretty but will not be flat. If you want a flat beautiful cylinder head mating surface, use a glass plate, or a marble or granite tile, as a reference. With an orbital sander you are not accomplishing anything other than polishing peaks and valleys

You put the dye on first. Your supposed to clean(clear stuff), then spray dye red stuff,then developer(white stuff) developer pulls dye through cracks for leak testing. To just amplify already visual cracks you could probably just use dye. If you had a crack in combustion chamber you could spray dye then put developer in water jackets and itll pull red through crack so its all white except a red line. Thats why you wait so the dye seeps into cracks.

I can get mine to spin in my driveway ( only cuz its gravel😃 )

Now this is an awesome video. I will be sure to share this on my Zuckerberg Matrix page and make the same.

Those rulers are nowhere close to accurate. Best to use the proper tool for the job.

I appreciate you bro, sick of people using full scare tactics that stop anyone from givin stuff a go, cheers

My brother had a set up that used a treadmill base,motor, variable speed controller for an AC 240 volt. Just a big belt sander! Cheers from Australia 👍

I just recently realized people shift from low gear to drive on pulls automatic but haven’t seen much on it. At least in the liberty, is it bad on the transmission? And what rpm do you shift from first, second, and drive?

What paint did you spray with on block

Thanks for the tips. I've always heard that you should take down the valve seats by the same amount, but I can't see how that's possible at home?

My 2003 liberty has survived 2 t bone accidents, driving in ditches, and careless lack of maintenance from my cousin. Now that it’s mine I’m surprised it even runs. They are TOUGH

If you try this. You have to go sideways between them the cylinders. I learned that the hard way had to take a Mitsubishi apart twice.

Thousandth isn't that much more to say.

I’ve never done a head gasket, but it may be in my future. I’m really glad I stumbled upon your video. Thank you sir.

My 4x4 '04 Dakota has the 3.7 Magnum dogsuk motor, at 15mpg. (With 3.9 gearing) I would watch the videos if you'll ever post them.

Where you getting 50 dollar heads at

as long as you don't want it flat

Imagine if Mercedes did this to your cyclinder head. 😂

You need to watch “Project Farm” video on air filters . K&N are HORRIBLE on Jeeps or offroad vehicles . They will dust and ruin your engine.. it is a Jeep not a corvette . And yea dont go in the water with that jeep no more either unless ya wanna hydro lock the engine.. the stock air box allows the engine to breath dry air in extremely wet conditions where K&N is just straight water to the engine .. But hey not my Jeep go for it ..

Good job, and I'm sure the machine shop boys will feel uncomfortable with the idea of sanding a head down flat, but ot works if you're dedicated and careful. It also means you're only removing the bare minimum of material by this method.

Is the head still assembled? Is it possible to surface the head without taking that all apart?

What finishing grit sand paper did you use?

Dude! Awesome! Thank you for the captions! Now I know what to use on the feeler gauge! Please keep making vids like this

Amico, una dima di precisione dovrebbe essere impiegata. Il righello in acciaio che usi non è rettificato e non è adatto per questo impiego

first time watcher, very intelligent and elaborate explanations thank you, that outro caught me off guard lol I did something similar to this for my 2014 SRT8 392 hemi (6.4L) cylinder head but now have a huge oil leak. I googled, and read that it has a Fire Ring or Fire Deck built into the cylinder head -- I used a straight edge file and it took off a little bit more around the cylinder bore than the rest of the head, I read filing down this Fire Ring can actually compromise and scrap the head. Do you know anything about these Fire Rings?

Try to get flat as possible, shop around for a thick head gasket, and use copper spray.

That's an ok technique. I guess. I prefer to use a cinder block. I just knock off the loose gravel and go to town. Works great. I'll throw some crisco on there every once in a while to keep it lubed. Head gasket seals fine. Just like yours will !! Keep on sanding.

Hello brother i wanted change my air box 2 to some applies to yours the problem is that sensors...show me how to transform it?

Just turn off traction control 🤦🏽‍♂️you get the same outcome

Vacuum leak

LOL lets take the airbox out that gets fresh air from outside and put in a system that gets hot air from under the hood... yup makes since.

There's not enough surface on the sander to keep the head flat not a good idea this guy doesn't know what he's talking about

Its not a liberty but it is a Nitro 3.7 4x4 and i definitely want more HP

why

Great video and tips. I am working on similar heads for my ford 4.0 SOHC. Lapping the new valves right now and holding onto the old valves to do some porting and polishing before fully reassembling things. Look forward to your upcoming video on the port and polish. This is my first go with SOHC heads, most of my experience is porting and polishing old V8 ford heads.

Yeah a head skim is very cheap if the heads actually known to have overheated id get it skimmed but if youre just building a motor up then id use emery paper over the whole head face but not a machine

How did you deck the block?

Update

Lies my will bark the fuck outta the tires stock

Nice for low budget guys like me...😂

What was the outcome

That is some Burt Monroe shit, awesome video. This is what a poor person like me has to do

Yeah I have an old Farmall Super A with a C123 engine. Need to fix a Crack on top surface, a new block cost $400 +$250 shipping. So it's not like I can make it broker. Worth a shot, gonna try lock n stitch cold sewing for Crack. If the set isn't to expensive.

My hand doesn’t even spend that much time on my KJ’s shifter, and I’ve got the NSG370 in mine.

I approve of this message however i disapprove your sanding table! I would have used a glass flat piece of glass as my sanding bench 🤷🏼‍♂️

Instead of using your workbench .buy a rem piece of granite . would get flatter surface for sure

Nah bruh my liberty does fat burnouts.
