Kohler CH18 Head Gasket Replacement 

nice to see John so polite and with manners.. very rare now a days. hes a good kid.

Gotta love the sound of a twin engine. 👍😄💗

Great video with you and your son. Took a calculated risk and it turned out well. Great job

Good Job on saving that engine. John is a great son and you are great Dad!!

Kohler really screwed us with that new air filter cover with the screw in the center. That's where the water gets in. Old commands had a cover that clipped on in the sides.

We have a 23 HP version of that motor in our Berco snowblower, and my Grandpa's got the 25 HP version in his GT5000. Both great, strong, and powerful motors. The one in the GT5000 is on its last leg, but that's because the tractor is a late 90's-early 2000's model, and it was never really maintained to great extents. It will be rebuilt soon, and will probably survive another lifetime. The one in the snowblower throws snow as far as the eye can see. Great motors.

I applaud you for turning shit to sugar.great job.

I had a Briggs 14hp opposed twin that I got out of a junkyard, it was packed full of water and surprisingly it runs great. All it needed was fresh oil and an ignition coil.

Hey Neil and John!! Great informative video. Thanks for sharing!! I put Marvel Mystery oil in the motor of the yamaha trimoto 200 that I found and I eventually got it to move. When I let it sit for a week it was locked up again. I turned it over a bunch of times and hopefully it will stay unsiezed this time.

Let the boy hold the motor down next time. That's how a boy learns, right? Good video. I'm working on the same thing in my JD317 w/18hp v-2 motor like yours, thanks.

Those Kohler command pro twin engines are wonderful engines if you take care of them slightly underpowered but work well almost had one explode today because it ran away like a 2 stroke detroit diesel due to the governor coming loose be careful when working on any engine. Big or Small Diesel or Gas.

My Kohler command pro 18 has 800 hrs and looks really nice, like new when I changed the head gasket. LOL I mainly came to see you torque the head down.

Good Video, I decided to look at some I had missed.

So very common in the Kohler CH series to have leaking head gaskets. All head gaskets on my Toro 520xi CH20s and 522xi CH22s have been replaced. One of them I could hear the leak at idle which was sometimes rough. Kohler sells improved head gaskets for them.

thanks, I learn a lot from your channel., Is there a channel for briggs and straton ? I got a 97 mtd garden tractor with a 18.5 hp. it has a oil leak on one of the cylnder. . you have in ibspured me to try and fix it. I use often for thibgs around the house, just have to keep filling it with oil. thanks

Cool video man. I was rooting for it to run. Super cool

It will run just fine no problem 👍

Great video! Awesome workshop! interesting project motor. how about putting the motor in a mud mower! :) :)

How do you get a kohl engine unlocked , it ran out of oil , 25 horsepower

Great Reading Material for that "RAINY DAY"!

fire it up, fire it up, fire it up, considering these engines now cost every bit of at least $2k they are well worthwhile repairing

Did you do compression test? If it has blowby it will choke engine out and have no power

I just picked up a welder with a CH20 and a few minutes in and I’m in the same situation but less water in the engine.

easy victory boys, Good job!

This would be the engine that I would put in John's "Bulldozer/Tank" Build!

Been watching your channel for awhile, always loved the GT6000 videos, and it got me thinking that basically the only thing they're missing that some other garden tractors of a similar level have is powersteering or hydraulic deck lift stuff like that, I was wondering if you could try and add hydraulics to a GT

Any advice on repairing my kohler ch20 I remover head got new style gasket said it would work on ch20 multiple models any ideas I’m pretty sure I can get it done just don’t know how to adjust the rockers or whatever first time doing this doing one side first then other side next help please ??

That moment at 11:28 is what the cylinder in my K321 probably looks like right about now after hosing it down with a punch of PB blaster, whatever was left of a can of WD40, and for good measure, a squirt of dry lube teflon in attempt to unsieze the previous owner's cook job it took. I could tell that for a '77 214, I was definitely the first one to ever open her up. Still had the factory air cleaner filter and a few pounds of dust between the filter housing and the carb... 🤦‍♂ One difference between northern and southern engines, instead of mice/rat nests, you find a prolific amount of field grass, snake skins and most often, pecan shells.

💯😎

Great camera work john nice to see father and son working as a team love your videos keep on keeping on the both of you cheers from the uk

Got to love the kholer engine's I myself prefer them.

Thanks for the video.

Hey! Where's the link for the Manuel?

thats sadness incarnate, i have a kohler cv22s its runs well though. its the same engine but more power, i needed new coils from a nest but i got then for free from the shop i work at and there wasnt water in it but gas from the fuel pump dying. thank god there was no water in the crank case.

Yea great build!!

Really fun video. I always look forward to your output. Did you leave a link for the universal hammer? LOL.

Good content, but common mann, with all that pitting you should have just honed the walls and got some new rings, it would have ran soo much better.

@redneckcomputergeek you think putting coke a cola in the parts cleaner will help eat rust and corrosion off of parts?

i think it'll be aright. you should see the flatheads mortske repair gets running.

Carburetor problem I know The feeling.. question can some one rebuild a mover but put muffler and carburetor on opposite sides the it begin with

you would be better off to glue sandpaper sheets various grits on to a flat work top slab, then rub the flat head surface on the flat sandpaper to get even flat mating surface of the head.

Heads should of been milled. They all warp and leak exhaust side ALL OF THEM.

30:55

It is still save it

He builds garden tractor puller

send that motor to me... I'll put it on a bycycle

It's not that bad😂☠️

Love that you’re teaching your son mechanics…… not to stir trouble but when you said ghetto mechanic all I could hear is far left screaming RACIST!!!!!! Just sayin. 🥴

Why would you goto all that trouble of slight teardown and putting money into carb and gasket set without tearing down all the way and atleast honing cylinders and new rings? Seems like a total waste of time and money. That engine isnt going to last very long with the cylinders in that condition and you know those rings had to of been stuck.

Your not supposed to just twist it anyways. Your supposed to let it soak with atf or penatrating oils.

hy if all falls on you I have a good core but need parts so I would love to pay you money if this engine dont work out for you

Not going to lie.. i thought it was not going to run without a top end rebuild.
