Re: Decarbed and compression went down!
I just remembered something. When I got my motor checked out a month ago they told me that one cylinder didn't pass the leak test. Could this be because of a bad head gasket? How would I find out what is causing the cylinder to fail the leak test?
hello,
do u mean a "leak-down" test? it is a rather involved process relative to compression test, and not a normal test to do or have done.
or do u mean why is the one cyl leaking more than others?
if later and u tested with other plugs in,
personally, if it was my engine... i would not worry about it at this time and i would go and enjoy the summer water.
an engine in good tune, will usually run fine even if one cyl reads a bit low. things to consider are does it run smooth in all rpms, does it run cool as it should. is throttle response good. it may not be as peppy as a new one, but it can still run with some sense of authority.
a weak engine can be kept in tip top shape for its condition with stepped up tunes and maint. such as change plugs sooner. dont abuse it. warm it up well when cold. avoid WOT throttle runs.
standing or otherwise. use dielectric grease to seal out moisture on electrics and plug ends. keep or make connections BRIGHT!
i learned about a leaking head gasket on my early evinrude only because i
had to pull it. so i got to inspect it. it was serviceable but only one thing can be said about carbon graying showing up past the cyl's compression o-ring on headgasket... she is a leaking... maybe not lots, but some blow by is happening.
