General Discussion / One of these studs is not like the other!
« Last post by Joshua on Today at 06:46:38 PM »On my 76' V1000 motor i have had a small but annoying head gasket leak.
So, in my effort to stop said persistent head gasket leak I have re-torqued the head. This lessened the leak some, probably to a tolerable amount, but me being me I could not be satisfied with that.
So off comes the head, gasket seized to cylinder mating face around the 10 o'clock cylinder stud. All the four o rings on the studs were hard and brittle when taking them off. Then off comes the cylinder which has the base gasket glued to the face of it with what looks like blue Permatex / liquid gasket.
All cleaned up and ready to install, base gasket down, o rings on studs at 12 and 6, cylinder down over piston, head gasket down, then comes the head.
All looks good to this point.
When I go to install the 4 remaining o rings on the cylinder studs I start with the 2, then the 4, then the 8. When I get to the 10 o'clock position where the previous head gasket was stuck on and there is no smooth stud showing? All I see are threads!!!
Off come the o rings and head and too my surprise, one of the head studs has a longer threaded portion, almost 1/4 of an inch? Also to my eye it may be a narrower stud overall?
This is my first guzzi motor, and first time breaking it down to any level outside of a valve adjustment.
Is this normal?? To have a different head stud?
I can't believe it would be good to have threads located where an o ring is supposed to seal oil from getting past??
Picture included, opinions on what to do are appreciated.
Is it very hard to set in a new head stud, are they available?
Many thanks,
Joshua

Way too many years of industrial noise, flying and motorcycling without hearing protection.. shooting guns..outrageously loud rock music.. Of course, I could read the information that hearing damage was cumulative.. but I chose to ignore it. Duh.
