    adjusting the valve clearance.

    Hey tone. i hope this message gets to you. I currently live in san diego
    california. I recently took my vx to an Isuzu dealership servicing center
    to have some scheduled maintainance done via ownersmanual says every
    60,000 miles adjust valve clearance. I don't know how to do the work myself and i can't find a hayes, or chiltons manual. But, anyway their trying to tell me that it's a deep engine knock,and their also trying to say i need a new engine that will run me 7300.00 sum dollars. I think it may be the lifter. the chattering is coming from the upper left. what do you think it may be, and do you know any place i can go to get this fixed, and fixed right.

    Valves should be adjusted at 60K but I have never done it and the Workshop CD does not describe it. A deep engine knock is bad and may indeed indicate a failing engine (spun rod bearing is most often the cause) and should run more like $5K. If it is indeed upper engine, any certified shop should be able to diagnose and repair properly.

    I will be in LA Mar 2-5th if you would like me to take a look at it.

    BTW, my email address is visible if anyone ever wants to contact me directly...

    There's a couple different places that the valve clearance adjustment procedure might be found. I'll take a looksee through the full tech library tomorrow if I get a chance.

    How much should a valve adjustment job cost? I have 106K miles, I doubt they were ever adjusted, my millage performance is lower than spec but the engine runs strong, it's a mean Vehicross, and I love it. The gasket kit with gromets and spark plugs seals are about $70 online, about half factory or autozone type pricing; how much should labor cost for this job? How much does Isuzu dealer charge? Anybody know? THANKS!! Erik

    This is an Isuzu tech video on adjusting the valves on our engine. It's small and a bit rough, but you'll get the idea.

    Mark, I don't know where you come up with these vids (is that you in the starring role? ), but they are of tremendous value to this community & I would just like to say Thank You!
    Also, I'd like to ask Moncha to include this one in the "how to" section along with the timing belt trilogy.

    The link to that video doesn't work anymore. Where'd it go? I need it.
