QG16DE Oil Leak

[brainmafia_310]

^^^ sorry sir TS ganyan na ganyan nangyari sa akin oil seal muna ng sparkplug bumigay. Kaya ung langis nasa ibabaw ng sparkplug. Pero nun binuksan sangkaterbang sludge na nasa cylinder kaya medyo may blowby na din ung sentra ko dati, in fact di nababasa ng oil ung sparkplug ko. Pero ayun pagkalinis nakita depekto at full overhaul na nangyari.

better look na lang kahit replacement brand wag lang 2nd hand (rubber material yan), sa mga auto supply wag na sa casa. gasket lang yun and not the valve cover mismo.

Sabi kasi ng mekaniko yung assembly ng tube seal nasa loob ng valve cover mismo. So is there a way ba para mapalitan yung seal na nasa valve cover?

which part of the sparking plug is wet with oil?
if it is the porcelain end, then it's probably due to oil dripping from a defective valve cover oil seal above.. this can be fixed by replacing the gasket with a new (never used!) seal.
but if the business end (sparking end) is oil-fouled, then it's probably worn oil scraper ("piston ring"), valve seal, head gasket, or (gulp!) cracked engine block.. ka-ching!!!

Tingin ko dun lang nag leak sa may spark plug tube. Hindi ko naman napapansin na nag babawas ng oil.

Ang problem kasi is mahirap sya i start kapag mainit na yung makina. Kapag sa umaga or matagal di nagamit isang start lang okay na. Kapag tinakbo na sya tapos nasa operating temp na then pinatay ang makina ayun ang hirap na i start. Kaya ginagawa ko tinatapakan ko gas habang i start yung makina.

sabi ng mekaniko basa daw kasi yung spark plug kaya mahirap sstart. But im not yet convinced kung yun ba talaga yung reason. kasi nasa spark plug tube lang yung may oil leak.
