the only way to fix a blown head gasket is to replace it. since your asking this im gona suggest either let the warranty take care of it or have someone else do it. should only take an experienced mechanic a couple of hours to fix this. if your not under warranty, i would check to see if theres any small engine mechanics nearby since you'll probably get a better labor rate.
Thanks for the replies. It is out of warranty & the manufacturer has not been any help. I have seen on line that after they have been fixed the head gasket blows out again in about 30 hrs,thats why I was wondering if anyone has heard of a fix for this (eg. bad head, bad bolts ect,ect) seems to be just the right side.
Thanks for any help.

i guess its possible that any one of those could be bad. its very important that the bolts be tourqued in sequence and that the surfaces be very close to flat. this can be checked by a machinest with a straight edge and fixed. the only other possibility is that the gasket is defective. maybe its a specific brand or something. it really isnt very hard to change a head gasket, but you have to make sure that you get everything right. the only special tool you'll need is a tourque wrench. a novice could probably do it in an afternoon, but make sure you have very detailed instructions. i dont know how much these gaskets run, but i cant see them being more than 50$ at the max. if you can get your hands on a tourque wrench, id give it a try. i've replaced head gaskets on single cylinder briggs motors in 10 minutes. o, you'll also need a feeler gage to make sure the pushrods are lashed to spec. if you need anymore specifics, your going to have to consult a book or a repair manual for specific bolt sizes and tourque specs and tourquing sequence. if you can turn a wrench, you can do this if you can follow directions. i would bet i could do this in under an hour, especially if there are no shrouds to come off the engine.
A few yrs back, Kohler did have prob with Command engines blowing head gaskets aand had a kit for such including different head bolts.

make sure you also replace the head bolts if only replacing the gasket or it will reblow the gasket within a few hours

I don't think he's asking for specific advise on replacing the gasket. I think he's asking if there is something different he could do to prevent it from happening again other than just replacing the gasket. Like a service bulletin from Kohler or something similar.

The main reason for blowing head gaskets on command engines is due to improper cooling like clogged cooling fins or restrictions due to covers on the mower. the excess heat warps the head blowing the gasket. the max warpage is .003 inch measured around the mounting surface when placed on a pane of glass or other flat surface. can be milled out with fine sandpaper in you want to spend the time and make sure to replace the head bolts and torque to spec. kohler had problems with the ch25 head gasket but that was corrected years back. if you order parts for your engine from any kohler dealer they will be the latest upgrade available. the main thing is to keep the cooling fins clean and do not use oil treatments such as stp or motor honey.
