Valve cover sealant

[raycon_24]

kahit new gasket ang ilagay kung di tama ang pag torque sa mga bolts magkaka leak pa rin, gamit ko yung T handle using only my right hand to torque the VC bolts on my civic just last week... take note crack na yung VC gasket ko, nilinis ko lang maigi yung mating surface ng VC at cylinder head using lacquer thinner and rtv sealant pioneer brand para sa crack na ang VC gasket until now wala paring tagas....

I found the problem. Putol yung VC gasket na nilagay ng mekaniko. Malamang natanggal sa pagkalapat yung gasket nung binalik nya ng yung cover, kaya naputol once na hinigpitan yung bolts. As I need to use the car this morning, nilagyan ko na lang ng sealant yung groove ng VC na wala nang rubber gasket. Ang ginamit ko na sealant ay yung Pioneer RTV Silicone na pula.

Thanks for all your help guys.

Sir, dapat original half moon at gasket bilhin mo ah.

Original naman yung half moon at gasket na nabili ko. Ok pa yung half moon nung binaklas ko kagabi, nilinisan ko na lang. Yung VC gasket, putol. Stupid mechanic. Lasing pa ata.

Observe mo na lang kung may lumusot na oil sa tapat ng putol ng gasket.

Sa bolt tightening of cylinder valve cover, dapat hindi bigla, meaning, screw on by hand ang nuts, pag hindi na kaya higpit by fingers, use a box wrench, unti-unti paghigpit on all bolts, huwag tight agad para pantay ang pressure ng gasket sa contact surface, that way less incidence of leak. Same procedure when installing engine oil pan at AT oil pan, do not over tighten agad para hindi mapiga agad ang cork gasket or whatever sealant gasket you are using, retighten later pag may napansin oil stain sa edges.

The proper way of replacing the valve cover gasket starts by cleaning the mating surfaces of old RTV residues. When placing the RTV, just place enough amount to the mating surfaces then replace the valve cover to the cylinder head. install the valve cover bolts then wait for at least 5-10mins to allow the RTV to gel up (RTV - Room Temperature Vulcanization) to promote better sealing. Torque the valve cover gasket bolts according to specs starting always from the center going out
