night rod blow head gasket twice
hello to all . my night rod special and this has turned to a nightmare ! need some tech help.
had low coolant ,mechanic filled up.
head gasket blew 2 miles later and compression was being heard from the front head.
had a new one installed. all fluids done again.
50 miles later, noticed that i was losing coolant again thrrough the side of the water pump cover where there is a little opening .
we changed all the gaskets for the water pump.
the leaking stoped there and there was coolant coming out of the side bolt covers...
then again, the head gasket blew and again losing compression and collant through the gasket and exhaust !
any ideas why collant comes out from the casing bolts under the water pump ? why it blows head gaskets ? the fan works fine. it never overheated on the gage...

Surfaces not flat?
Torqued incorrectly?

hello to all . my night rod special and this has turned to a nightmare ! need some tech help.
had low coolant ,mechanic filled up.
low coolant why? was the coolant system pressure tested? plugs bleach white? oil have water it? milky color oil or under dipstick cap?
head gasket blew 2 miles later and compression was being heard from the front head.
did gasket blow/torch? head lift? fasteners torque to yeild?
had a new one installed. all fluids done again.
50 miles later, noticed that i was losing coolant again thrrough the side of the water pump cover where there is a little opening .
we changed all the gaskets for the water pump.
right.. weep hole for the waterpump shaft/gasket
the leaking stoped there and there was coolant coming out of the side bolt covers...
not sure here.. bolts penetrate water jacket? thread sealant used?
then again, the head gasket blew and again losing compression and collant through the gasket and exhaust !
and exhaust?? is it smoking blue/grey out exaust?
