to start the story
for the past few years the dip stick was coming out when the motor was running, so I tided it down so that it was not popping out.
it uses about a 1/2 cup of out after about 4 hours of use. not bad.
so today I check the oil down the 1/2 cup of oil so I fulled it up.
oh this is the GT I use for my FEL
I was work on turning out my compost plie - 7 pick-up loads of sheep manure
got done in around a 1/2 hour and putting it back in the garage and I notice oil on the floor
checked the oil and down over the 1/2 cup oil and oil all over the front of the motor
had to mow the yard and it had to wait to work on it
got the FEL off and moved into my work shop
cleaned the motor off and started it up to see where the oil is coming from
it was coming from the gasket area for the oil pan
the bolts looked a little loose.
will it is time to see what is wrong
pulled the motor out and checked the oil pan bolts - all 4 bolt were loose.
so I wanted to know way I was having so much blow by.
removed the oil pan - all looked good inside
removed the head and the piston
checked the rings on the piston and the oil rings were all aligned up
checked the side gap on the rings and all are less then 0.005 ( good)
remove the top ring to check the cylinder wear
used the ring to check the gap in the cylinder and around 0.045 checked the rest of the cylinder .
checked 3 different spots in the cylinder and all were around the 0.045 gap
so I was going to just hone the cylinder and put it back together
good plans allow go bad
while putting the top ring back on the piston it broke ( oh sh**)
now I guess new rings, I just as well do it right and do a good overhaul
that way it will last almost another 40 years
my question is why and how did the oil rings align up?
and why after 40 years did the oil pan bolt get loose?
