Re: Sand in center cylinder

wha?

that's a great diagnosis.  did the tech not provide you with an
explanation as to a vector of entry?  that's the first question i'd get
asked if i told somebody that.

maybe i'm forgetting something.


through the plug hole....(?)

through the intake, which you cannot really see 'cause it's buried under
that ridiculous exhaust....

through the exhaust, did you flood the unit or something?

if a gasket was compromised eough to pass sand throught it, the sand
wouldn't get a chance 'cause the water would take care of business long
before...  i'd think...

do you have any pictures>>?????


through the exhaust because it lines up with center cylinder could be
remotely possible, but damn that's odd.

chances are if they rebuild without finding out EXACTLY what happened
you're looking at another hosed-ass cyl again.

the guy who works next to me basically says 'water ingestion' at any
type of piston failure, and it drives me nuts.  then the engine kills
itself again and he gets all pissed ( as does the customer)

make sure they do their homework.
