    Frustrated? no just pissed that this has happened with mowing season just around the corner. Only the top lifter refuses to pump up and only on the #1 side,no# 2 has no issues. Some how has you said,there's an airlock, as this engine ran fine before and after for twenty minutes and next day oil problems.
    If I am able to get this all sorted out,a mechanical( Solid) cam will be replacing this hydraulic cam this coming winter.

    If oil pressure is good,I'll attempt to prime that #1 bank and thanks for the tip on the MELLING lifters

    I see a few things wrong with this thread, This was asked early on;

    And still no numbers posted, READ the sticky above this section people and others can respond with better info !!!

    Next..... The engine was "rebuilt" and now it is a replacement "shortblock"......

    Engines can be just like tires, Aired up then flat seconds later.....Maybe coincident it started making noise after the oil change..... Who knows ???

    If this was a new shortblock install, Does anyone know if adding the breather kit to the new updated block is causing a issue ? I've never been "boneheaded" enough to install one of these kits in the new style block......

    Hey Piston Slapper I have two kholers that I'm thinking on rebuilding. Parts I'm looking at around $550 the problem is I never get no more than around 1000 hours on the rebuild. But I was thinking you said your rebuilts can go from 3 to 4. Thousand hours.if I drop the engine at your shop how much you charge for your services.:waving:

    What do you want to be when you grow up? If you answered, "mechanic," you're in the minority. But that could be a good thing for your chances of getting a job. As USA Today points out, a shortage of mechanics and an increase in the complexity of today's lawn mowers means there's big demand for wrenchers.:waving:

    I don't care who ya are...... That right there is [​IMG]

    That couldn't be further from the truth, Anyone with a set of harbor freight wrenches and stanley screwdrivers can be a wanna be parts changing "mechanic"...... The shortage is in "Service Technicians"...... That's right, The ones that have to go behind "mechanics" and sort their mess out.....

    Regarding the new short block I purchased, I bought it from a gentleman who had it built years ago to keep in stock and I bought at a decent price but disassembled the SB to assure myself that indeed it was built using genuine kohler parts and all was good. So yes, this bonehead did in fact install a up dated kit to resolve the air locking issues #24-755-135S on this particular block and it worked out till now. The HP rating was posted earlier, highly doubtful Kohler produced it in a single or the K-block which would leave only the V-twin but I can see where there might be some confusion ,my bad.
    The oil pressure readings at idle where 40 lbs and 45 lbs F/T,so'I'll be purchasing some lifters and go from there and will never return to this section of the forum for assistance.

    RestroRob...you know me as good as anyone on this site...
    I don't get along with people as well as I do with engines..and I'm Ok with that..
    That character flaw has enabled me to become one of the best in what I do...
    Trust Me...if I don't like or respect a prospective customer...it ain't gonna get fixed..:waving:
    It took years of hard work and more than my share of eating crow...to earn this respective position...
    If you want to talk tech....you've come to the right place..
    If you want to trash techs...Bring Your A Game...:walking:

    The key with rebuiding engines comes from knowledge not just blind parts changing. Top builders refer to this as balancing and blueprinting. Removing all the minute flaws that come mass production. Smoothing and improving oil flow. Tightening tolerances to their closest range. Using improved materials where you can. Ovekill? Only in some peoples books. I take personal pride in assembling the finest product available. Anybody can swap factory or mass repops. Not my gig. I do all my own work and even a little for guys that know me. Doesn't matter if its old auto iron or a defunct specialty engine. Mechanics is my therapy these days.
