    Hindi na dapat lagyan ng anumang pandikit ang head gasket bagkus ay pinapahiran ng oil ito para maganda ang lapat ng gasket sa magkabilang sides(cyl head to block).

    Hindi dapat lagyan ng pandikit pag naglalagay ng cyl head sa engine block. Ito pa nga ang maaaring pagsimulan ng singaw dahil sa init (magiging tutong ung sealant at magkakaroon ng crack na pagdadaanan ng singaw).

    Correct! Big no no ang paglagay ng RTV pag cylinder head gasket na ang pinag uusapan. Grabe kasi ang init and pressure na iniinda ng cylinder head gasket. Any RTV or gasket sealant na ilagay ay siguradong lulutong pag tumagal, and yun ang pwede maging tagasan ng oil papasok ng cylinders (galing sa oil valleys).


    What I can recommend for DIY'ers is a very thin and even layer of oil na ipahid both sides. any excess will seep out naman once you bolt your cylinder head using a torque wrench.


    ang shellac na gasket sealant, mare-recommend ko sa crank case gasket, same with the valve cover gasket. Had a bad history when it comes to silicone gaskets, maski hi-temp pa siya.

    Depende sa conditon ng head, kung bagong refaced ung head hindi na kailangan lagyan, langis o grasa lang para gumanda ang lapat nito. Kung medyo alanganin ka sa gasket areas lagyan mo ng shellac kalimitan sa mga mekaniko ang gumagamit nito pag hindi nareface at overheat ang problema ng makina disadvantage lang nito pag kinalas uli mahirap alisin at linisin.
    Never for RTV sa head gasket.
    Straight edge at feeler gauge naman ang pagcheck ng cylinder head for warpage in several locations.
