always run in my Chevy Duromax since it was new and have 300,000
miles on it and never done anything to it.

<div dir="auto">Hi everyone, got my 1st
non antique non red tractor this summer.
Kubota 62 horse 4wd. Nice shape overall
and a good price. However it makes a
noise that seller said dealer told him
it was a lifter adjustment, but it turns
out not so. We have had this engine
apart several times and cant find
anything wrong, bearings are all good,
no broken rings, out of spec bores,
pistons all good.
<div dir="auto">At odds trying to figure
this out, and dont want to destroy
this engine by running it too much.
Just yesterday, replaced all the
injectors and cups with new as the
sound is like a bad injector, but to
no avail, noise is still there. The
engine is an F2803 5 cylinder which
seems to be not as common as most. </div>
<div dir="auto">Does anyone know of any</div>
<div dir="auto">Reputable dealers for
used engines?</div>
<div dir="auto"> I have attached a
link to video where you can hear the
noise. Any and all suggestions and
comments welcome.</div>
