I have changed liana's gaskit 2-3 times and also got the head faced last time but it has started reducing water again..
My mechanic suggested me to change the head assembly with a kabli one...
Currently its m13a pak assembled but i want to inquire that is it possible to change only assembly with m16a or i have to change with m13a only?
Moreover is it reliable to get the assembly changed or not? Means it worth it or not?
Approximate cost ?
And lastly any experienced liana mechanic in isb or rwp?
