good video....just an fyi for those doing this at home  1. a flat piece of 2x4 on top of valve cover and a tap with mallet is much better than using a screwdriver to pry!  2.  do NOT use so much gasket sealant when reinstalling valve cover, 1/16" bead is proper

Thank you. Damn, that sounded like a new engine when it started up!

Mu favorite channel on YT. I don’t even work on stuff. Just satisfying to watch. Thanks for the content.

I’ve always had good luck with Kohler engines!

Oh thanks mine is bad smells up the whole yard when I run it. This will probably end up being a lifesaver honestly haha😂😅

I will be tackling this project before spring.

i think this is the last of your old videos i have watched as yet...now ive watched them all...we need more lol

When you first pulled off the cooling tins I expected to see a mouse nest under the tins, then as the video ran along and you said the fins were filled with grass clippings it all made sense to me, that inadequate cooling was the culprit, just that it had already been cleaned. I drove up a very steep road with my pentastar and it finally overheated and I immediately stopped and came home before any damage occurred. I had replaced the thermostat last spring but it was an aftermarket job and cracked while installing it. Must get another.

Good instructional video on this head gasket replacement, you made it very easy for the average DIYr to follow along.  I have this exact engine on my Snapper ZT18440kh mower and noticed fumes coming out of the oil dipstick tube recently so may be doing this procedure myself.  Looks pretty straight forward from your video; glad you took all the “re-torque” guess work out of the procedure, one less thing to look up online:-)  This is the first small engine I have come across in a long time that has self adjusting valves.

You should run a tap into those exhaust manifold threads.
Before re-installing, put a bit of ANTISIEZE on the bolts.

Wouldn't you want to check your oul level before starting the engine after the repair?
Excellent video, naarative, and mechanics work!
Thank you for sharing!

If the only problem you had is a blown gasket,  you got lucky.  
I was working on a Briggs and stratton,  it had some serious problems.  The intake valve guide moved towards the valve head and held the valve open.  I thought it just needed a valve job. WRONG , I took it to a machine shop,  he removed the guide,  knurled the guide,  and replaced the guide.  Heated the head with a propane torch to remove and replace.  Then ground the valves, and seats.  It was in pretty bad shape.  I doubt it could have been lapped in, the seats were in really bad shape.  It runs great now.

One thing I might have done differently,  is I used 150 grit sandpaper on a flat smooth surface and resurfaced the head,  and the block to have a good flat mounting head and block.  I did that with the Briggs.  I don't know If it helps or not but in my mind a flat service will help.

Very helpful video, especially torque values. I also encourage others to check cooling fins. My  CV15S ran hot one spring and I discovered a family of mice had set up housekeeping. They also chewed the coil wire, I guess I was lucky not to have had a fire. I keep my mower in an outside shed.

Some of the lawn tractors I get free from our town's transfer station cost a lot of money but had zero maintenance done like the JD 105 I'm currently bringing back. The deck mounts had broken off from the vibration caused by loose blades. It only has 198 hours on it.

Great Video, I have an LT155 and having the same problem. This video make it easy to work on!! Thanks.

Thanks for posting this, nice having torque settings, good pace, and clear video. Just did the same job with your help. Excellent!

Great video man! I'm having the similair issues with my old mower, thank you!!

Great video, thank you.Answered a lot of my questions!

just found this video very impressive thanks

Saved me two installations of the pump by watching this video before I stumbled through it myself.
